The ATC SCM20A SL Limited Edition is a special anniversary loudspeaker created to celebrate the beginning of ATC’s 50th Anniversary year. In addition, this exclusive model combines ATC’s renowned active loudspeaker technology with premium craftsmanship, making it one of the most desirable limited-edition speakers the company has ever produced.
Limited to just 150 pairs worldwide, the SCM20A SL Limited Edition delivers the same uncompromising performance that ATC is known for while introducing a stunning high-gloss blue finish and hand-upholstered dark blue Napa leather front baffle. As a result, it offers both exceptional sound quality and distinctive visual appeal.
Exclusive anniversary design
ATC developed the SCM20A SL Limited Edition to mark a significant milestone in the company’s history. Therefore, every detail reflects the brand’s commitment to engineering excellence and craftsmanship. In addition, the luxurious high-gloss blue cabinet and full-grain Napa leather baffle create a striking appearance that sets this model apart from the standard range.
Reference-grade active loudspeaker system
The SCM20A SL Limited Edition combines ATC’s proprietary 150mm Super Linear mid/bass driver with the acclaimed 25mm S-Spec dual-suspension tweeter. As a result, it delivers exceptional clarity, tonal accuracy, and dynamic performance across the entire frequency range. Furthermore, the compact sealed enclosure ensures precise timing and controlled bass reproduction.
Integrated active amplification
Each loudspeaker includes ATC’s proven active amplification system. Therefore, a dedicated 200W Class A/B MOSFET amplifier powers the bass and midrange driver, while a separate 50W amplifier drives the tweeter. In addition, this active design provides superior driver control, greater dynamic range, and improved overall accuracy compared to passive systems.
Advanced analogue crossover technology
The SCM20A SL Limited Edition uses analogue 2nd-order Linkwitz-Riley active crossovers. As a result, the crossover network achieves precise driver integration and improved phase accuracy. Furthermore, an additional all-pass filter optimises performance through the crossover region, creating more natural tonal balance and highly focused stereo imaging.
User-adjustable room optimisation
The rear panel includes adjustable input sensitivity and low-frequency shelf controls. Therefore, users can tailor the speaker’s performance to suit different source components, room acoustics, and personal preferences. In addition, balanced XLR inputs ensure seamless integration into high-performance audio systems.
Matching limited-edition subwoofer available
To complement the SCM20A SL Limited Edition, ATC also produced a matching C4 Sub Mk2 Limited Edition. Consequently, owners can create a visually and sonically integrated system with extended low-frequency performance. Like the loudspeakers, the subwoofer features a gloss blue cabinet, leather-upholstered baffle, and premium finish.
Hand-built in England
Every SCM20A SL Limited Edition loudspeaker is hand-built in England to ATC’s exacting standards. As a result, each pair benefits from meticulous assembly, extensive testing, and exceptional build quality. Furthermore, ATC supports the speakers with a comprehensive 6-year warranty for long-term peace of mind.
