ATC Launches Statement EL50 Anniversary Loudspeaker

The EL50 Anniversary active 3-way tower is the latest evolution of ATC’s winning design blueprint.

ATC is delighted to introduce the EL50 Anniversary to audiophiles and music lovers seeking long-lasting high performance, design and engineering quality. It’s the latest evolution of the legendary ATC 50 loudspeaker design, featuring discrete active tri-amp technology first deployed by the SCM70 in the 1990s and refined through the SCM50 Anniversary speaker in 2004 and the SE Series in 2014. Its industrial design draws from the EL150, released in 2006, the first ATC loudspeaker to employ an elliptical enclosure and designed by Billy Woodman. Leather detailing on the front face and beautiful hand-selected veneers further elevate the design.

New Discrete Active Amp-Pack

This advanced new model incorporates a new, proprietary 3-channel active ‘Amp-Pack’ featuring balanced input, user controls, active crossovers and three power amp channels, delivering 200W, 100W and 50W continuous power to the bass, mid and high-frequency channels, respectively. Within the first line level stages, new discrete gain blocks have been developed and implemented within a balanced instrumentation input and the fourth-order active crossovers to achieve a lower noise floor and reduce distortion. In addition, the power supply has been comprehensively re-designed and upgraded with individual toroidal transformers for each power amplifier channel, plus a separate transformer serving the low voltage supply. This topology improves headroom under demanding use and reduces intermodulation distortion between the channels to deliver greater clarity to the listener.

Cabinetry and Finishing

Building on previous development work, the EL50 Anniversary cabinet construction has been improved and updated via advanced in-house manufacturing technology to increase stiffness and internal damping, reducing cabinet-borne colouration in the upper-bass and mid-range. The bass driver is mounted into a precision turned aluminium ring which is bolted into the cabinet face, further increasing cabinet integrity. A curved cabinet face and edges create a smooth transition from the driver output into the room, reducing edge diffraction and producing a more uniform on and off-axis frequency response for reduced linear distortion. Hand-selected and matched European walnut veneers cover the curved elements of the cabinet complemented by ebony inlays on the rear panel and finished with a high-gloss polyester lacquer. Upholstered napa leather panels around the mid and high-frequency drivers and the lower front section add a contrasting texture while integrating cleanly with the cabinet’s overall form.

Drive Units

The drive unit complement is built entirely in-house with a focus on low distortion and consistent performance at all playback levels with any source material. The SH25-76S ‘S-Spec’ tweeter uses a compact but exceptionally powerful neodymium motor, a dual-suspension system to precisely control the coil motion, and a coated fabric dome for smooth, uniform on and off-axis response. The critical mid-band is reproduced by ATC’s SM75-150S ‘Superdome’ mid-range driver, covering 380Hz to 3.5kHz. Its combination of high-power magnet drive system and large voice coil mated to a dome diaphragm results in a driver system that can resolve the smallest musical details while effortlessly handling the largest dynamic peaks found in complex recordings. Completing the system, the SB75-234SL bass driver features ATC’s Super Linear motor system for reduced 3rd harmonic distortion in the upper-bass/lower-midrange resulting in improved clarity and integration with the mid-range driver. At the lowest octaves, an optimised spider-roll-surround pairing allows large linear excursion for controlled low frequency output.

The EL50 Anniversary launches as an exclusive run of 50 pairs, each supplied with a hardbound owner’s handbook. The book celebrates ATC’s journey from its origin as a drive unit specialist in 1974 to its status as one of the world’s most highly respected loudspeaker manufacturers, revered by music lovers and audiophiles, and trusted by hundreds of international recording and mastering studios.

The new EL50 Anniversary will make its global debut at The Bristol Hi Fi Show, Friday 20th – Sunday 22nd February 2026.

ATC Announces New SSM Series Wall/Ceiling-Mount Monitors and R4-150 Pro Quad-Mono Power Amplifier

Stroud, Gloucestershire, UK – ATC is expanding its professional loudspeaker portfolio with the introduction of the SSM Series, a new generation of shallow, wall and ceiling-mount passive studio monitors designed for modern control rooms, surround and immersive audio environments. The range launches with two models – the SSM12i Pro and SSM25i Pro – alongside the new R4-150 Pro, a four-channel power amplifier that makes an ideal partner to the new loudspeaker series.

Designed for Space-Critical Installations

Both SSM models feature very shallow enclosures – 147 mm / 5 13/16” for the two-way SSM12i Pro and 198 mm / 7 13/16” for the three-way SSM25i Pro – including mounting hardware. This enables integration into control rooms where room width, depth and ceiling height are critical constraints.

The cabinets can be mounted in either portrait or landscape orientation and use a robust mounting system that attaches flat to a wall or ceiling. A pivoting mechanism allows precise aiming toward the mix position, enabling improved imaging, and in-room response.

Both enclosures incorporate internal steel reinforcement and a safety-tether point to meet the practical requirements of secure professional installation, particularly for overhead mounting.

SSM12i Pro – 2-way

The SSM12i Pro is a passive two-way loudspeaker engineered around ATC’s proprietary drive-unit technology and housed within a sealed cabinet optimised for on-wall/ceiling installation.

Low and mid-range is handled by the SB45-150CLD 150 mm driver, whose Constrained Layer Damping (CLD) cone minimises breakup modes while maintaining linear behaviour across the operating band. Above the 2.2 kHz crossover point, ATC’s SH25-76 25 mm dual-suspension soft-dome tweeter provides low distortion and excellent high-frequency resolution.

Together with a newly developed crossover network – modelled and fine-tuned specifically for on-wall operation – the SSM12i Pro delivers high resolution, controlled dispersion, and accurate translation with compact control & mix rooms.

SSM25i Pro – 3-way

For medium to large control rooms, including those used for mixing Dolby Atmos and other immersive audio formats, the SSM25i Pro offers improved bandwidth and output via a three-way sealed design and three ATC proprietary drive units.

Low frequencies are handled by the SB50-164SC 164 mm/6.5” driver featuring a short-coil/long-gap motor and paper/carbon-fibre composite cone. Mid-range duties are performed by ATC’s renowned SM75-150 75 mm/3” soft-dome – known for its exceptional clarity and minimal coloration – while high frequencies are managed by the SH25-76S tweeter, featuring a high-flux motor to deliver an extended high-frequency response and very low distortion.

The crossover network has again been engineered specifically for boundary mounting, ensuring the speaker delivers ATC’s signature neutrality and transient accuracy even when installed close to surfaces and perfect integration with ATC’s range of active loudspeakers and subwoofers.

Physical Specifications (Selected)

SSM12i Pro (flat portrait orientation inc. hardware):

• 517 × 315 x 147mm / 20 3/8 x 12 3/8 x 5 13/16 ” (H x W x D).
• 14.8 kg / 32.6lbs.

SSM25i Pro (flat portrait orientation inc. hardware):

• 767 × 380 x 198mm / 30 3/16 x 14 15/16 x 7 13/16” (H x W x D).
• 28.2 kg / 62.2lbs.

Due to weight and overhead mounting considerations, SSM Series products must be installed
by qualified professionals. Both models ship with mounting hardware drilling templates.

R4-150 Pro — Quad-Mono Amplification for Professional Multi-Channel Systems

To complement the SSM Series, ATC introduces the R4-150 Pro, a new 5U rack-mount, quad-mono power amplifier built around four independent power supplies and class A/B MOSFET output stages.

Each channel delivers 150 W continuous, making the R4-150 Pro ideally suited for the dynamic demands of immersive audio and multi-channel playback or bi-amping passive nearfield monitors. Balanced inputs are provided via four XLR connectors with very high common-mode rejection, while outputs use Neutrik NL4 sockets for a secure and reliable connection.

With convection cooling for silent operation and built-in thermal and DC-offset protection, the R4-150 Pro is designed for reliable long-term use in the most demanding professional studio installations. A remote power-on/off trigger further simplifies integration into larger control systems.

ATC Unveils High-Output SCS140iW Pro 2×12” and SCS240iW Pro 2×15” In-Wall Subwoofers.

Stroud, Gloucestershire, UK: ATC is proud to introduce its SCS140iW and SCS240iW Pro subwoofers, new dual-driver in-wall models evolved from the established 12” SCS70iW Pro and 15” SCS120iW Pro designs. Representing ATC’s most powerful in-wall subwoofer systems to date, these models deliver significantly increased output and performance for modern stereo, surround and immersive monitoring environments.

The larger SCS240iW Pro has been engineered for the largest control rooms, stereo and immersive formats and for seamless integration with ATC’s SCM300AiW main monitors. The SCS140iW Pro, meanwhile, is ideally suited to partner the SCM200AiW main monitors and performs equally effectively as a dedicated LFE solution for surround and immersive formats such as Dolby Atmos. Both subwoofers provide extended low-frequency capability and exceptional headroom, enabling accurate monitoring in demanding professional environments.

SCS140iW Pro

The SCS140iW Pro is a new 2×12” design that builds upon the strengths of the proven SCS70iW Pro by utilising a pair of 12”/300 mm drivers and dual remote amplifiers. This upgrade delivers a 6 dB increase in output, achieving a continuous SPL capability of 116 dB and a peak of 121 dB at 1 m. Despite this performance, the cabinet remains compact, with a width that matches the SCM200AiW in-wall main monitor for a cohesive visual and acoustic pairing. The SCS140iW Pro can also partner smaller ATC models or complement any system requiring extended bass performance with high SPL and headroom.

SCS240iW Pro

Designed for the largest control rooms, the SCS240iW Pro is the most powerful and linear subwoofer manufactured by ATC. Evolved from the SCS120iW Pro, this new 2×15” design doubles both the driver and amplifier complement, resulting in a 6 dB increase in output over its predecessor. It delivers 119 dB continuous and 126 dB peak SPL at 1 m.

The cabinet width matches the SCM300AiW main monitor, creating an impressive full-range in-wall system when installed together. The SCS240iW Pro may also be used alongside ATC’s larger mid-field monitors — including the SCM150A Pro — or integrated into any system demanding a low cut-off frequency with high dynamic range.

Drive Unit Technology

The 12”/300 mm and 15”/375 mm drivers used in the SCS140iW Pro and SCS240iW Pro are built entirely in-house by ATC, reflecting the company’s commitment to designing and manufacturing products from component level without compromise. Both drivers feature a 30 mm magnetic gap, which is 50% longer than previous generation bass drivers. This extended gap reduces motor-generated distortion while enabling the high excursion required for accurate, dynamic low-frequency reproduction. Every element of the driver — from the motor to the suspension — has been meticulously optimised using advanced analysis tools to deliver deep, controlled bass from 120 Hz down to below 20 Hz, all with minimal distortion and maximum impact.

Amplifier Technology

Power for the new subwoofers is provided by dual R1-300 Pro remote-mounted 7U/19” amplifiers, each using 300 W Class A-B output stages. Their rack-mount format offers installation flexibility, allowing the amplifiers to be located within a nearby wall, a control-room rack, or a machine room. Amp connections are made using NL4 speaker cables and 5-pin XLR. The amplifiers offer balanced stereo inputs and full-range balanced outputs, with analogue 4th-order Linkwitz-Riley filters providing multiple crossover options including an industry-standard 80 Hz setting and a bypass mode for use with external processing. Polarity switching, variable phase adjustment and a stepped attenuator allow precise system alignment. The amplifiers also feature convenient mute control via footswitch, with daisy-chain capability for multiple subs.

Both subwoofers are available to order now.

SCS140iW Pro is available at a UK RRP (Recommended Retail Price) of £7700 + VAT including 2 x R1-300 Pro remote power amplifiers (excluding cables).

New SCS120 Pro & SCS120iW Pro: Powerful New Subwoofers for Studio Monitoring

Stroud, Gloucestershire, UK:  ATC is proud to unveil two new flagship 15″/375mm active subwoofers — the SCS120 Pro and SCS120iW Pro — designed to elevate professional monitoring systems to new levels. 

Engineered to support ATC’s larger mid-field and main monitors, these subs deliver exceptional low-frequency extension, expanded dynamic range, and seamless integration for stereo, surround, and immersive formats including Dolby Atmos. The SCS120 Pro has been designed for use free-standing, and the SCS120iW Pro includes features ideal for flush/in-wall mounting.

Building on the success of the 12” SCS70 Pro, but both models feature a new hand-built 15”/375mm sub-bass driver, developed and manufactured by ATC at their facility in Gloucestershire, England.  All driver components and parameters – from the drive system to the suspension – have been precisely optimised using the latest analysis tools available, at both small and large signal level.  The result is an advanced transducer that combines a powerful short-coil motor system featuring optimised airflow and cooling, with a carbon-paper composite cone, resulting in deep, clean bass from 120Hz down to below 20Hz — with minimal distortion and maximum impact. 

The SCS120 Pro subwoofers deliver an extended low-frequency response without complex electronic equalisation or processing, instead employing the more elegant combination of exceptional transducer engineering and a marginally larger cabinet volume.  Such simplicity reduces phase shift and group delay, aiding the integration of the sub with the partnering monitor loudspeakers.  Ultimately, it delivers a more balanced and coherent experience for the listener, combining an extending low-frequency response with outstanding clarity in the upper bass.

Both new subwoofers are powered by a 300W class AB amplifier, hand-built and optimised for fast, dynamic response. Versatile connectivity & control includes balanced stereo inputs, balanced (full-range) outputs, and analogue 4th order Linkwitz-Riley filters with multiple crossover options — including an industry-standard 80Hz setting and bypass setting for external processing. A polarity switch, variable phase control, and stepped attenuator allow precise system tuning.  For added convenience, the amp features mute control via footswitch, with daisy-chain capability for linking multiple subs.

The SCS120iW Pro (In-Wall) variant offers all the above-mentioned performance but is optimised for flush in-wall mounting, featuring a shallower cabinet, and recessed rear input connector panel, maximising floor space. The accompanying R1-300 Pro remote-mounted 7U/19” amplifier offers the user the flexibility to install the amplifier in a suitable wall close to the subwoofer, in a control room rack, or in a machine room, with connections made via NL4 speaker and 5-pin XLR cables.

These two new subwoofers are the perfect match to the ATC SCM100/110/150A Pro studio monitors and scale effortlessly to larger systems featuring the SCM200/300A Pro main monitors. Multiple subs can be employed to elevate performance and to fill larger rooms.

Surround and Immersive Audio formats such as Dolby Atmos can be demanding of subwoofers, and these two new designs both offer significant performance gains over the smaller ATC SCS70 and the outgoing SCM0.1/15.

Thanks to employing advanced transducer and amplifier technology, the new SCS120 and SCS120iW Pro subs offer increased dynamic range and low frequency extension, strengthening the upper range of ATC’s Professional Product line.  They offer improved subwoofer solutions to users of mid-to-large format monitors and/or to those working in larger control rooms.  The increased dynamic range on offer is particularly useful in in immersive audio and post-production applications where low frequency effects (LFE) content places large demands on subwoofers.

The SCS120 Pro and SCS120iW Pro are available now. 

The recommended UK retail price for the SCS120 Pro is: £4575+ VAT.

The recommended UK retail price for the SCS120iW Pro is: £5408 + VAT (inc. R1-300 Pro remote amp, excluding cables).

The 2-way SCM20ASL continues ATC’s philosophy of combining the best in-house drive units with matched on-board amplification for optimal fidelity. Uniting the benefits of compact size and wider bandwidth with the improved phase coherence, response speed and dynamics of ATC active operation, the SCM20ASL is perfected for small to medium sized listening environments. In addition, its sealed cabinet design ensures exceptionally well controlled bass even in smaller spaces and/or when located close to walls.

Key Features

• 150mm/6” ATC ‘Super Linear Mid/Bass driver loaded in a compact sealed cabinet.
• 25mm/1” ATC ‘S-Spec’ soft-dome dual-suspension HF driver.
• On-board ATC active 250W ‘Amp Pack’ module.
• Balanced input and 2nd order Linkwitz-Riley active crossovers.
• User adjustable input sensitivity and bass shelf controls.
• 2 x class A/B MOSFET power amplifiers, 200W Mid/Bass and 50W high frequency.
• Hand-built in England.
• 6-year warranty.

Integrating a 2-way active system within a 20-litre stand-mount cabinet, the new model features ATC’s proprietary 150mm/6” ‘Super Linear’ Mid/Bass driver and 25mm/1” ‘S-Spec’ dual-suspension tweeter, powered by on-board class A/B MOSFET power amplifiers capable of delivering 200W and 50W continuous power to the bass and HF drivers respectively. The performance and power output of each power amplifier is carefully tailored to driver demands and the musical elements they reproduce.

The Mid/Bass driver employs a large 75mm/3” voice coil and short-coil (long-gap) motor assembly featuring ATC’s proprietary ‘SL’ motor technology, which reduces distortion from the upper bass into the midrange.  ATC’s 25mm ‘S-Spec’ soft-dome tweeter features a dual-suspension and very high energy 2.1 tesla motor combining to deliver an extended response well beyond 20kHz with the exceptional reproduction of fine detail.

Crossovers are active, analogue 2nd order Linkwitz-Riley operating at line-level for maximum efficiency, while an all-pass filter is included to optimise the phase response through the crossover region, resulting in far improved tonal balance and imaging.

Input to the loudspeaker is via balanced XLR, located on the rear panel and there are user controls for input sensitivity and low frequency shelf cut and boost. The input sensitivity control allows the user to tailor the input gain to suit their source and pre-amplifier combination for more consistent performance. The low frequency shelf control gives the user the option to subtly adjust the bass response to suit their room.

The SCM20ASL cabinet features a combination of bracing for stiffness and damping to supress resonance and is available in a wide range of real wood veneers, painted satin finishes and high gloss lacquers. Standard finishes include Cherry, Black Ash, Walnut and Oak veneers, Satin Black or Satin White paint. Premium finishes include Rosewood, European Crown Cut Walnut, Burr Magnolia, Pippy Oak veneers. The speaker is supplied with a removeable grille, wrapped in black acoustically transparent cloth.

Why Active?

In the quest for the best possible performance, all high-quality loudspeaker system manufacturers will have struggled with the limitations of passive crossover networks. Even though excellent results are possible from passive systems, a multi-way loudspeaker system will only realise its true potential if implemented as an active design. There are a few practical and economic reasons why passive speakers have remained so popular in the Hi-Fi market but, focusing on objective performance alone, active loudspeaker systems offer the following advantages:

• More accurate crossovers due to fixed filter ‘load’.
• Wider practical choice of crossover type/shape due to active line level operation.
• Greater dynamic range due to elimination of passive crossover losses.
• Ideally matched amps and more efficient use of amplifier power.
• Improved frequency response and stereo matching due to speaker-amp calibration.
• Better driver control: a more direct connection to the drivers with far lower electrical resistance.
• Lower inter-modulation distortion due to reduced amplifier operating bandwidth.

The new SCM20ASL will make its global debut at the Axpona show in Chicago, from Friday April 11th. 

Availability: April 2025

ATC LAUNCHES C4 SUB MK 2 ACTIVE SUBWOOFER SYSTEM

New proprietary 12-inch driver, optimised motor mechanics and a 300W Class AB amplifier combine to deliver exceptional levels of performance for audiophile music and film devotees.

World renowned for its signature high output, low-distortion audio engineering and trusted by musicians, studios, live sound engineers and audiophiles over five decades, The Acoustic Transducer Company (ATC) is proud to announce the production of the C4 Sub Mk 2 active subwoofer system. Designed to unite the highest standards of driver and electronics engineering in a single system, the C4 Sub Mk 2 deploys the all-new proprietary 12-inch SS75-314SC sub-bass driver, powered by a newly developed 300W class AB amplifier design, both elements hand-built and installed within a substantial cabinet at the company’s Stroud-based production HQ.

New ATC Sub-Bass Driver
The C4 Sub Mk 2 features the new SS75-314SC sub-bass driver, the first to be purpose-built for an ATC sub-bass system and developed by the R&D team to reproduce the lowest four octaves of the audio band. In order to achieve this the design exploits ATC’s signature long-gap/short-coil configuration to its natural limits with an exceptionally long 30mm magnetic gap, surrounded by a 6-inch/150mm N48M Neodymium magnet – the most powerful ever assembled by ATC and a first for the company. In support, the wholly redesigned motor system features a new rubber roll-surround for high excursion capability, a new spider for optimised compliance geometry, and high flow motor venting for low noise and compression.

As well as minimising distortion, this unprecedented short-coil long-gap configuration ensures the voice coil remains within the motor structure – even at high drive levels – maximising cooling, reducing power compression, and improving reliability.  Turbulent air noise within the driver is minimised by a large, flared vent running through the centre of the motor structure, which has the added benefit of increasing voice coil and motor cooling.

Consequently, the C4 Sub Mk2 delivers an extended low-frequency response while avoiding electronic equalisation, unlike many subwoofers available today. Instead, the more elegant combination of exceptional transducer engineering and a marginally larger cabinet volume is used.  The simplicity of this approach reduces phase shift and group delay, aiding the integration of the sub with the partnering loudspeakers.

New 300W ATC Amplifier

The all-new 300W class AB design is precisely optimised to the requirements of the new driver, resulting in fast, dynamic bass with minimal colouration. Two balanced line inputs provide connectivity for stereo or AV/home cinema systems while two balanced outputs are available to feed partnering ‘main’ stereo loudspeakers or to ‘daisy-chain’ multiple subs. Low-pass filters are analogue, 4th order Linkwitz-Riley, with filter frequency options ensuring optimal integration with partnering speakers. In addition, an industry-standard 80Hz low-pass filter and an ‘off’ option (for use with external processing) are joined by a polarity switch, variable 180° phase adjustment and a stepped attenuator over a 21 dB range for precise level matching.

The C4 Sub Mk 2 Cabinet

Hand-built and finished at ATC’s cabinet factory and sharing styling with the brand’s ‘Classic’ and ‘Tower’ series loudspeakers, the C4 Sub Mk 2’s 70 litre cabinet employs 25mm/1-inch thick panels and heavy bracing.

VANCE POWELL INSTALLS ATC MONITORS FOR SPUTNIK SOUNDS DOLBY ATMOS IMMERSIVE STUDIO

Nashville, Tennessee – October 2023: Vance Powell recently completed a studio makeover at Sputnik Sound, installing the popular ATC 7.1.4 Dolby Atmos monitor system to add the future of immersive surround sound to his arsenal. In 2014, Powell, an innovator in studio design, teamed up with producer Mitch Dane in a rambling house in the famed Berry Hill section of Nashville, naming it Sputnik Sound and filling it with virtually every audio tool past and present. A producer, engineer, mixer, and winner of seven Grammy awards, his credits read like a Billboard list of chart-topping artists: Phish, Chris Stapleton, Jack White, The White Stripes, The Raconteurs, and Buddy Guy for starters. His career has spanned from working with Jars of Clay, to a chief-engineer role at Blackbird Studios, to outside work with many of Jack White’s groups. With his new Dolby Atmos room, Powell has complete control to mix immersive audio in his singular style.

As soon as Dolby Atmos Immersive Sound Systems hit the marketplace, Powell was on it. Consulting with the Dolby engineers and famed studio designer Michael Cronin, Powell tore apart his existing control room, totally rebuilt the front wall, re-installed his existing SSL 6000 console and selected ATC monitors for his 7.1.4 system. For left and right configuration, Powell chose the ATC SCM110ASL, an active three-way reference monitor with high-resolution, featuring twin nine-inch ATC “SL” bass drivers, an ATC three-inch soft dome midrange, and an ATC one-inch “S-Spec” soft dome tweeter. The center channel is handled by an ATC SCM50ASL, the company’s benchmark design for a world-class loudspeaker with a sweet-sounding, refined ATC tweeter, ATC soft dome midrange and massively engineered ATC bass driver. Four ATC SCM25A three-way active studio monitors deliver for the surrounds and four ATC SCM12i two-ways for the overhead channels, again all featuring ATC drivers. Dolby engineers worked with Powell for exact speaker placement. The LFE emanates from an ATC SCM0.1/15 Pro Sub capturing the low end with clarity and efficiency.

Dolby Atmos Immersive Sound promises to give the listener the feeling of being in the room with the musicians, noted Powell. “ATC monitors have always impressed me for their clarity and tonal balance. Same goes for the ATC Atmos system performance in immersive audio. It’s perfectly nuanced listening and meets all Dolby standards. All this technology helps me fully realize great music. I’m really happy in this room.” Powell recently completed the Atmos mix of The War and the Treaty’s Lover’s Game album and the 49 Winchester’s Fortune Favors the Bold. “The new Atmos system allowed me to give these already beautiful, organic records an added layer of depth,” said Powell.

“If you’re ready to bring your studio into Dolby Atmos, listen to an ATC system. Their sound is so musical and accurate, somewhat hard to describe,” added Brad Lunde, president and founder of TransAudio Group, ATC’s U.S. distributor. “But when you hear them, you’ll know exactly what I’m talking about.”

ATC 7.1.4 IMMERSIVE STUDIO MONITORS CO-STAR IN STARSTRUCK STUDIOS’ DOLBY ATMOS ROOM

NASHVILLE, TENNESSEE – SEPTEMBER 2023: ATC Loudspeakers legendary reputation just got better. And why not? Top studios worldwide are accustomed to their pristine sound. Today, the ATC 7.1.4 Dolby Atmos system is cited as the speaker system of choice for the growing number of multichannel immersive sound studios. Manufactured and designed in the UK to the highest engineering standards, it was only natural ATC could develop this solid niche. One of the top iconic Nashville recording facilities, Starstruck Studios, chose an ATC 7.1.4 Dolby Atmos configuration and paired it with their SSL System TS-500 console for their Dolby Atmos room.

Starstruck Entertainment, the parent company of Starstruck Studios was founded in 1988 by Narvel Blackstock, who remains in control.  Over the last 25 years, Starstruck has developed and managed top selling acts, including Blake Shelton, Carly Pearce, Maggie Rose, Emily Ann Roberts and have recorded artists such as Carrie Underwood, Luke Bryan, and Taylor Swift in their studios.  Famed for its’ unique studios – The Gallery and The Pond – Starstruck opened their Dolby Atmos room in the spring of 2021.  Starstruck ranks as one of the most chosen recording, production, and mix venues on Music Row.  Top recording engineers, such as multiple Grammy-award winner Chuck Ainlay, frequent the facility.

 

Noted Nashville-based acoustician, Michael Cronin, Michael Cronin Acoustic Construction, designed and built the mix room at Starstruck. Cronin, an expert at meeting Dolby’s strict guidelines, re-worked Starstruck’s existing lounge and listening room into a Dolby immersive sound studio.  Cronin had years of exposure and experience with ATC speakers and suggested the ATC Dolby Atmos system would work perfectly in the new studio.  Narvel Blackstock and the Starstruck staff engineers concurred as most were familiar with ATC monitor performance and value.  The ATC system purchase was made through Westlake Pro Audio in Nashville.

Shawn Daugherty, Starstruck’s chief technical engineer, installed, calibrated, and integrated the immersive system room.  The ATC 7.1.4 system is composed of three  ATC SCM110A Pro handling left-center-right, four ATC SCM45A Pro for surrounds, four ATC SCM25Ai Pro for height, and two ATC SCM0.1/15 subwoofers.  Noted Daugherty, “Accuracy, placement and performance are strategic in meeting the specifications of a Dolby Atmos system. The ATC system was strikingly easy to calibrate.  In fact, when the Dolby engineers came out for the final tuning, they literally could copy and paste settings from one speaker to another – somewhat of an audio rarity.  The ATC’s detailed tonal balance and exact reproduction makes it hard to imagine working in a studio that doesn’t have them.”  One of the first recording engineers to use the Dolby Atmos room was Derek Bason, who was mixing tracks from Carrie Underwood’s catalog into Dolby Atmos.

Todd Tidwell, Starstruck’s chief engineer, concluded, “The ATCs live up to the hype and are worth every penny you pay for them.”  He used the system for various projects for Carly Pearce in the July 11 CMA Fest in Nashville.  “The ATCs are a joy to work on. I’m super confident I’m hearing every detail from every angle.  Basically, you just have to hear it for yourself.”

ATC announces SCM25A Pro Mk2 – compact, three-way active studio monitor as evolution of popular predecessor…

ASTON DOWN, GLOUCESTERSHIRE, UK: ATC is proud to announce upcoming availability of the SCM25A Pro Mk2, a compact, three-way, high-performance active monitor — maintaining the core of its popular predecessor from which it evolved while refining key areas of design and performance, including replacing the original SCM25A Pro’s OEM (Original Equipment Manufacturer) high-frequency driver with the specialist British manufacturer’s own ‘S-SPEC’ SH25-76S soft-dome, dual-suspension tweeter, as fitted to the two-way SCM20A Pro and larger, three-way SCM45A Pro, SCM50A Pro, SCM100A Pro, SCM110A Pro, and SCM150A Pro models since 2015.

As a compact, three-way, high-performance active studio monitor, the SCM25A Pro Mk2 is based around a 6.5”/164mm bass driver loaded in a vented enclosure, tuned to 32Hz and featuring a 3”/75mm diameter port with flared entry and exit to minimise port air noise.  It’s exceptional combination of exceptional mid-range clarity; high-output, extended bass response; and modest 25-litre/0.9 cubic foot size make it ideal for nearfield monitoring across a wide range of critical applications.

All new to the SCM25A Pro Mk2 is its high-frequency driver, replacing its popular predecessor’s OEM part with its own ‘S-SPEC’ SH25-76S, which is manufactured in-house with a no-compromise engineering approach (as fitted to the two-way SCM20A Pro and larger, three-way SCM45A Pro, SCM50APro, SCM100A Pro, SCM110A Pro, and SCM150A Pro models since 2015). This driver is a 1”/25mm soft-dome design, handling high frequencies above 3.5kHz, but, unlike almost any other 1”/25mm tweeter on the market, it employs both an upper and lower suspension to better support and control the coil and dome motion. This, therefore, makes for a narrower magnetic gap, resulting in higher magnetic flux, which, in turn, extends the high-frequency response and reduces 3rd harmonic distortion.  As ATC R&D Manager Richard Newman notes, “We feel the new tweeter lifts the capability of the SCM25A Pro Mk2 to a higher level, retaining the outstanding balance of the monitor, but extending the high-frequency response and reducing distortion to really help lower-level detail in the high-frequency band cut through. This will greatly aid faster decision-making and outstanding translation outside of the studio.”

 

Meanwhile, mid-band frequencies between 380Hz and 3.5kHz are handled by ATC’s acclaimed 3”/75mm soft-dome mid-range driver, duly combining high-efficiency, high-power handling, low distortion, and wide dispersion characteristics to ensure class-leading performance for the SCM25A Pro Mk2 in this critical frequency range. As a mainstay of ATC’s Pro product range, this component features in eight models, making certain consistency spans from nearfield through to main monitors.

Mid- and high-frequency elements are supported by a 6.5”/164mm proprietary bass driver that takes care of the SCM25A Pro Mk2’s low frequencies below 380Hz. This features a carbon-loaded paper cone while the driver motor employs a short-coil operating in a long magnetic gap, helping to minimise distortion generated by drive force modulation. Additionally, a large 2”/50mm voice coil and generous excursion capability ensure outstanding dynamic range.

Rear-mounted, a three-way class A/B amp actively drives the SCM25A Pro Mk2 with each drive unit having its own dedicated power amplifier.  Audio balanced input is via a rear panel-mounted three-pin XLR and power is via an IEC  mains power inlet.  Input sensitivity and Bass boost controls are also accessible to the user.  Ultimately, crossovers are 4th order Linkwitz-Riley and all-pass filters are included to optimise the phase response through the crossover regions, improving the tonal quality and imaging, as well as on- and off-axis frequency response. Furthermore, FET (Field-Effect Transistor) peak limiters are included to reduce amplifier ‘hard-clipping’, while Power/Limit is indicated — ‘on’ and ‘active’ — by a front panel-mounted bi-colour LED.  Just like the cabinets and loudspeaker drive units, the amplifier is designed and manufactured in-house.

The SCM25A Pro Mk2 carries a UK retail price of £7075 per pair + VAT and will be available from 1^st March (country/region dependent).

“The delights of active operation for hi-fi loudspeakers have long been known, but few manufacturers venture from passives. All the more surprising, when you consider the sonic fireworks that have resulted from ATC turning its already excellent SCM40 floorstander, and adding internal Class AB power amplification and active crossovers. Put simply, the SCM40A punches way above its weight – turning it into a giant killer at a still reasonable and accessible price. Great clarity, power, dynamics and punch make for a highly expressive listen – one that makes music move you.”  Stereonet UK, December 2022

ATC Launch SCS70 Pro and SCS70iW Pro 12″ Active Subwoofers

ATC are very proud to announce the availability of two new high-performance 12″/300mm active subwoofers, the SCS70 Pro and SCS70iW Pro, designed to deliver the exceptional levels of performance demanded by audio and music professionals and integral to partnering with ATCs range of renowned active studio monitors.  Their performance and features make them ideally suited to stereo, multi-channel surround, and immersive audio formats such as Dolby Atmos.  The SCS70 Pro has been designed for use free standing and the SCS70iW Pro has been optimised and includes features ideal for flush/in-wall mounting.

Advancing ATC’s proven philosophy of developing loudspeaker systems from component level up the subwoofers feature a new sub-bass driver, developed by ATC’s R&D team, and optimised for reproduction of the lowest four octaves of the audio band.  To best achieve this, it is designed with a 30mm magnetic gap, 50% longer than any other offered by ATC.  The long-gap and short-coil configuration takes a long-standing ATC design feature to its limit, minimising distortion while simultaneously delivering the high linear excursion required to produce accurate and dynamic low frequency output.  Generating a high level of magnetic flux over such a long gap required extensive FEA computer modelling and the resultant 6″/150mm N48M Neodymium magnet is the most powerful ever assembled by ATC and a first for the company.  As well as minimising distortion, the short-coil long-gap configuration ensures the voice coil remains surrounded by the steel motor structure at all times, maximising cooling, reducing power compression, and improving reliability.  Turbulent air noise within the driver is minimised via a large, flared vent running through the centre of the motor structure, which has the added benefit of increasing voice coil and motor cooling.

The SCS70 Pro subwoofers deliver an extended low-frequency response without employing electronic equalisation, quite unlike many subwoofers available today. Instead, the more elegant combination of exceptional transducer engineering and a marginally larger cabinet volume is used.  The simplicity of this approach reduces phase shift and group delay, aiding the integration of the sub with the partnering monitor loudspeakers.  Ultimately, it delivers a more balanced and coherent experience for the listener, extending the low-frequency response without masking details or changing the tonal character in the upper bass/lower mid-range.

Drawing on 34 years of experience in amplifier design and development, ATC’s electronic engineering team have delivered an all-new amplifier for these two new subwoofers.  The 300W class AB design is hand-built by ATC at their UK facility and precisely optimised to the requirements of the drive unit, resulting in fast, dynamic bass with minimal colouration.  Two balanced inputs provide connectivity suited to both stereo and multi-channel/immersive audio systems plus two balanced outputs provide connections to monitor loudspeakers or to ‘daisy-chain’ multiple subs.  Low-pass filters are analogue, 4th order Linkwitz-Riley and filter frequency options ensure optimal integration with a wide range of studio monitors.  An industry-standard 80Hz low-pass and an ‘off’ option (for use with external processing) are also provided.  A polarity switch plus a continuously variable 180° phase adjustment allows further optimisation of the subwoofer crossover and a stepped attenuator with a 21 dB range provides precise level matching.

SCS70iW Pro

Integrating active subwoofers designed to operate ‘free-standing’ into control rooms designed for flush/ in-wall monitoring can be a challenge, but the SCS70iW Pro (In-Wall) is dedicated to this application, simplifying installation, and ensuring optimal performance.  Featuring a shallower cabinet and recessed input connector panel it maximises floor space while the accompanying R1-300 Pro remote mounted 7U/19” amplifier offers the user the flexibility to install the amplifier in-wall close to the subwoofer, in a control room rack or in a machine room.  Connection between the in-wall sub and remote amp is via NL4 speaker cable and 5-pin XLR cable (sold separately & available in multiple lengths).

Output of the SCS70 Pro can be muted via a single latching footswitch connected via the mute Input ¼” / 6.35mm jack).  Additional  subwoofers can be muted using the same footswitch, connected via the mute ‘Thru’ jack.

The size and performance of the SCS70 Pro make it the ideal partner for a wide range of ATC studio monitoring loudspeakers, including the SCM12 Pro, SCM20A Pro, SCM25A Pro, SCM45A Pro and up to and including the SCM50A Pro.  Multiple subs can be employed to elevate performance, to fill larger rooms and also when partnering with larger models of loudspeakers.  Buffered linkable inputs and outputs makes connection of multiple subs simple as does the linkable ‘mute’ circuit.  Surround and Immersive Audio formats can be particularly demanding of subwoofers and these two new designs both offer exceptional clarity at higher SPLs.  It is recommended that the Dolby Audio Room Design Tool (DARDT) should be used to aid the design of ATC monitoring systems for Dolby Atmos, ensuring the format guidelines are met and best possible performance is achieved.

Designed and engineered with a focus on resolution and integration, the SCS70 and SCS70iW Pro offer users additional low frequency extension and dynamic range but without compromising balance in the upper bass and lower mid-range.  They provide an upgrade path to customers owning smaller monitors and lacking space for larger mid-field or main monitors whilst also offering a greater choice for surround and immersive audio applications.  Whichever way anyone chooses to use them, the new SCS70 Pro and SCS70iW Pro are two strong additions to the Professional Series product line-up.

The SCS70 Pro and SCS70iW Pro are available now.  For a list of authorised ATC distributors and dealers, please see here.

The SCS70 Pro UK recommended retail price is £3125 + VAT.

The SCS70iW Pro UK recommended retail price is £3750 + VAT (inc. R1-300 Pro remote amp).
