ATC SCM20 ASLT 2-way Active Floorstanding Speakers

The ATC SCM20ASLT tower loudspeaker is a long standing tradition in the ATC line-up, with custom wood finish’s such as rosewood, the SCM20 is a truly handsome loudspeaker. The speaker uses a simple 2 way design that incorporates a special dome on the midrange driver that helps deliver the unique midrange ATC is famous for. The SCM20 became a definitive classic monitor during the mid 90’s. It took over 3 years to develop and represented ATC’s first venture into affordable domestic monitoring.

Central to its performance is the mid/bass unit designed by Billy Woodman and hand made in house at ATC. The hybrid design incorporates a 150mm bass cone on to which is grafted a 75mm soft dome. The magnet assembly utilises ATC’s unique “SL” technology which greatly reduces distortion in moving coil drive units by a very significant 12-15dB (3rd harmonic). To minimise Time Domain Distortion both dome and cone are made from acoustically “dead” polyester wave material doped with ATC’s own formulation.

Not only does the SCM20 Series reproduce bass with remarkable articulation and authority, it also has outstanding mid-band clarity, incredible dynamic range, and awesome power handling. The active version is powered by the ATC “Grounded Source” Bi-amplifier. The bass/mid is driven with 250 watts, while the tweeter has 50 watts of class “A” power.

Both amplifiers feature momentary gain reduction circuitry which both protects drive units and prevents unpleasant sounds from overdrive. Accompanied by either ATC SCA2 or CA2 preamp the SCM20AT will out perform any other combination in its price range any many costing far more.
