ATC is introducing the three-way EL50 Anniversary loudspeaker, as the latest evolution of its longstanding ATC 50 design.
Featuring discrete active tri-amp technology, first deployed by ATC in its SCM70 model from the ’90s era, and refined through the SCM50 Anniversary speaker in 2004 and then the SE Series of 2014, its industrial design draws from the EL150, released in 2006 (the first ATC loudspeaker to employ an elliptical enclosure, designed by Bill Woodman).
Its proprietary 3-channel active amp-pack boats balanced inputs, user controls, active crossovers and three power amp channels, delivering 200W, 100W and 50W of continuous power to its bass, mid and high-frequency channels respectively.
Its re-designed power supply sports individual toroidal transformers for each power amp channel, plus a separate transformer for the low voltage supply, for improved headroom.
The EL50 Anniversary loudspeaker’s drive units are built entirely in-house and include an SH25-76S ‘S-Spec’ fabric dome tweeter with neodymium motor and dual-suspension system.
For mid frequencies, ATC’s SM75-150S ‘Superdome’ mid-range driver is installed, covering 380Hz to 3.5kHz thanks to a high-power magnet drive system and large voice coil, mated to a dome diaphragm.
Completing the line-up, the SB75-234SL bass driver employs ATC’s Super Linear motor system for reduced 3rd harmonic distortion in the upper-bass/lower-midrange.
And those slender yet wide cabinets? They’re high-spec too thanks to extra stiffening and internal damping with the bass driver mounted within a precision turned aluminium ring that’s bolted into the cabinet face.
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 with upholstered napa leather panels.
Limited to an exclusive run of 50 pairs, each supplied with a hardbound owner’s handbook, visit ATC to find out more and hear them for yourself at this weekend’s Bristol Hi-Fi Show.
