The SSM series of passive loudspeakers is engineered to provide accurate, consistent monitoring when mounted on control room walls or ceilings. Featuring shallow cabinets and a versatile mounting bracket solution, these loudspeakers offer flexible installation options. They are an ideal choice for multichannel and immersive audio setups - including Dolby Atmos systems - in control rooms where space is at a premium, but reference-level performance is essential.
The SSM12i Pro is a compact, passive 2-way loudspeaker built around proprietary drive units designed and manufactured by ATC. The speaker can be wall or ceiling mounted in vertical or horizontal orientations. In addition, the mounting hardware allows the cabinet to pivot away from the wall/ceiling surface, directing more of the output towards the listening position resulting in a superior balance and precise imaging.
