ATC SCM20SL Classic Passive Hyllykaiuttimet

SCM20

Overview

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 SCM20SL reproduce bass with remarkable articulation and authority, it also has outstanding mid-band clarity, incredible dynamic range, and awesome power handling.

The active tower version (SCM20ATSL) is powered by the ATC “Grounded Source” Bi-amplifier. The bass/mid is driven with 200 watts, while the tweeter has 50 watts of class “AB” power.

Both amplifiers feature momentary gain reduction circuitry which both protects drive units and prevents unpleasant sounds from overdrive.

Accompanied by either an ATC SCA2, CA2 preamp or CDA2 MkII the SCM20AT will outperform any other combination in its price range, many costing far more.

An all-time classic still available and in any veneer to special order.
