ATC SCM20ASL 2-way Active Standmount Speakers Launched

The SCM20ASL, based on ATC's 50th-anniversary Limited Edition design, becomes the British brand's most compact active model.

The 2-way SCM20ASL features ATC's in-house drive units with matched amplification, which results in optimal fidelity, according to the company.

The ATC SCM20ASL sports a 20-litre standmount cabinet that houses a proprietary 150mm (6-inch) Super Linear Mid/Bass driver and 25mm (1-inch) 'S-Spec' dual-suspension tweeter, powered by onboard class A/B MOSFET power amplifiers capable of delivering a claimed 200W and 50W continuous power to the bass and HF drivers respectively. The manufacturer adds that each amplifier's performance and power output are carefully tailored to driver demands and the musical elements they reproduce.

We're told that the mid/bass driver employs a large (75mm/3-inch) voice coil and short-coil (long-gap) motor assembly featuring ATC's 'SL' motor tech, said to reduce distortion from the upper bass into the midrange. This is paired with ATC's 25mm 'S-Spec' soft-dome tweeter, which marries a dual suspension design with a high-energy 2.1-tesla motor. ATC says this results in an extended response well beyond 20kHz alongside exceptional reproduction of fine detail.

Crossovers are active, analogue 2nd-order Linkwitz-Riley operating at line-level. An all-pass filter is included to "optimise the phase response" through the crossover region, resulting in far improved tonal balance and imaging.

Around the rear, you'll find balanced XLR input and controls for input sensitivity and low-frequency shelf cut and boost. The input sensitivity control allows you to tailor the input gain to suit your source and pre-amplifier combination for more consistent performance. Meanwhile, the low-frequency shelf control enables adjustment of the bass response.

The SCM20ASL cabinet combines bracing for stiffness and damping to suppress resonance and is available in a wide range of real wood veneers, painted satin finishes and high gloss lacquers. Standard finishes include Cherry, Black Ash, Walnut and Oak veneers and Satin Black or Satin White paint. Premium finishes include Rosewood, European Crown Cut Walnut, Burr Magnolia, Pippy Oak, and Burr Poplar veneers. The speaker has a removable grille wrapped in black acoustically transparent cloth.

The new SCM20ASL makes its global debut at the Axpona show and will be available from April 2025. Suggested pricing starts at £6,495 for standard finishes and £7,295 per pair for premium finishes. Add £1,595 for high-gloss lacquer over veneer. Those preferring Piano Black or White will pay £7,845, while custom finishes can be discussed. Regional pricing has yet to be confirmed.
