ATC’s New SCM20ASL Limited Edition Loudspeakers Make Us Blue With Envy: AXPONA 2024

In celebration of the beginning of its 50th Anniversary, ATC is proud to announce the forthcoming release of an exclusive new active stand mount loudspeaker, the SCM20ASL Limited Edition.

ATC SCM20ASL Limited Edition Speakers with Subwoofer

There is definitely some confusion when it comes to “active” loudspeakers; Bluetooth and wireless loudspeakers certainly fall into the broader category but they are not the same thing as “powered” loudspeakers that need to be connected to a source with volume control or a pre-amplifier.

ATC’s passive and active loudspeakers are extremely popular in both pro and high-end audio circles for their linearity, superb dynamic capabilities, and deeply engaging sonic performance.

All active loudspeakers are “powered” by nature (some are even naughty ;-)) but not all powered loudspeaker are active.

The new ATC SCM20ASL Limited Edition are active loudspeakers because they feature separate power amplifiers inside each loudspeaker; both the tweeter and midrange driver/woofer have their own amplifiers, active crossovers, and do not require a connection to the other in order to work. 

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 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.

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.
