ATC Announces New Limited Edition SCM20ASL and C4 Sub Mk2


In celebration of the beginning of its 50th Anniversary, ATC is proud to announce
the release of the exclusive Limited Edition SCM20ASL and C4 Sub Mk2.


Las Vegas, NV, April 10, 2024 – World renowned for its signature high output, low-distortion audio engineering and trusted by musicians, studios, live sound engineers and audiophiles over five decades, The Acoustic Transducer Company (ATC) is proud to announce the SCM20ASL Limited Edition loudspeaker in celebration of ATC’s 50th Anniversary.

Limited to just 150 pairs, the 2-way active stand-mount design is finished in a stunning high gloss lacquer in the ATC company dark blue. Complementing the cabinet, 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 striking contrast to the blue lacquer and leather of the cabinet and baffle.

The SCM20ASL Limited Edition continues ATC’s philosophy of combining the best in-house loudspeaker drive units with matched on-board active amplification for optimal fidelity. The new model integrates a 2-way active system, previously only available in a floor standing model, into a smaller stand-mount cabinet. The SCM20ASL Limited Edition 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-litre sealed cabinet and power is provided by on-board 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, analogue 2nd 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.

Input to the loudspeaker is via balanced XLR, located on the rear panel and there are user controls for input sensitivity and low frequency shelf cut/boost. The input sensitivity control allows the user to tailor the input gain to suite their source/pre-amplifier combination, resulting in a more consistent performance. The low frequency shelf control gives the user the option to subtly adjust the bass response to suite their room and/or their personal taste. The speaker is supplied with a removable grille, wrapped in dark blue acoustically transparent cloth.

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. 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), IL, which will take place from April 12 to 14 in 2024.
