EL50 ANNIVERSARY

ATC is delighted to introduce the EL50 Anniversary to audiophiles and music lovers seeking long-lasting high performance, design and engineering quality. It is the latest evolution of the legendary ATC 50 loudspeaker design, featuring ATCs discrete active tri-amp technology, renowned drive units and a new elliptical curved cabinet for optimal radiation from the mid and high-frequency drive units. 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.
