acoustic transducer company scm20asl

The Acoustic Transducer Company (ATC) announced the SCM20ASL Limited Edition loudspeaker. Limited to just 150 pairs, the two-way active stand-mount design is finished in a “high gloss lacquer in the ATC company dark blue.” The front baffle is hand-upholstered in royal blue full-grain Napa leather by German leather specialist Eissmann. The exterior alloy components feature a silver anodized finish in contrast to the blue lacquer and leather of the cabinet and baffle.

The SCM20ASL Limited Edition is a two-way active system and features ATC’s proprietary 150mm/6” “Super Linear” Mid/Bass driver paired with a 25mm/1” “S-Spec” dual-suspension tweeter.

The bass driver operates in a 20-liter sealed cabinet and power is provided by onboard class A/B MOSFET power amplifiers, capable of delivering 200W and 50W continuous power to the bass and HF drivers respectively. The loudspeaker crossovers are active, analog second order Linkwitz-Riley and an all-pass filter is included to optimize the phase response through the crossover region, resulting in far improved tonal balance and imaging.

To support the SCM20ASL Limited Edition, a limited run of 20 of ATC’s new 12” active subwoofer, the C4 Sub Mk2 Limited Edition have been produced. These limited-edition subs feature a matching gloss blue cabinet, leather upholstered baffle and silver anodized amp hardware.

The SCM20ASL Limited Edition and matching C4 Sub Mk2 Limited Edition are available to order now and will start shipping in mid-April. The speakers are limited to 150 pairs and the subs to 20 pcs.

The product will make its World Premiere at the Axpona Hi-Fi Show, exhibit room #1534 in Schaumburg (Chicago), Illinois, which will take place from April 12-14, 2024.
