ATC Loudspeakers

ATC Loudspeakers are engineered by the UK’s Acoustic Transducer Company, renowned for designing and manufacturing some of the finest professional and domestic audio systems available today. By producing every driver in-house, ATC ensures that each loudspeaker delivers the highest standard of performance, fidelity and durability.


Rather than simply keeping pace with competitors, ATC has continually pushed the boundaries of what true high-fidelity performance can be. Their goal has always been to create loudspeakers and ATC amplifiers that operate as close to perfection as engineering will allow.


Whether in tower, floor-standing or bookshelf form — and offered in both passive and active configurations — ATC loudspeakers offer exceptional flexibility for high-performance systems. At Brian & Trevor, our team is on hand to guide you through matching the right ATC series to your room, amplifier and system preferences.


Precision British Craftsmanship Meets Lifelong Reliability - every ATC loudspeaker is built to last, carrying a 6-year warranty and engineered to meet the demands of both current high-resolution digital recordings and tomorrow’s standards. From the bookshelf SCM7 to the flagship SCM300 ASLT active tower, ATC’s range covers all listening environments with unwavering accuracy.

ATC SCM50SL / SCM50ASL Loudspeakers

The SCM50 ASL (active) and SCM50 SL (passive) are designed to perform at their best in the recording studio or at home with the finest quality hi-fi equipment.


The monitors’ ability to reproduce music and speech with phenomenal accuracy, transparency and dynamics lies mainly in the SM75-150S soft dome midrange driver. However, recent modifications that include the new ATC SH25-76S tweeter and enhanced port profile have brought about further improvements to all performance parameters.


Each drive unit in the active model has its own dedicated and individually matched MOS-FET amplifier, while the 234mm/9″ bass driver incorporates ATC’s unique Super Linear Magnet technology. Our active crossover network consists of a wide band-width, electronically balanced input stage with high common mode rejection and very low distortion.


Like the HF, mid and bass drivers, all electronics are designed and manufactured in-house to create a no-compromise active system. In passive form, the SCM50 SL provides broad and symmetrical dispersion, excellent amplitude and phase characteristics throughout the frequency range.


Speakers are supplied with stands and fabric wrapped grills.


ATC SCM100SL / SCM150ASL Loudspeakers

The SCM100 ASL (active) and SCM100 SL (passive) are designed to perform at their best with the finest quality hi-fi equipment.


Like their smaller brother, the SCM50 ASL, the monitors’ ability to reproduce music and speech with phenomenal accuracy, transparency and dynamics lies mainly in the SM75-150S soft dome midrange driver. However, recent modifications that include an upgraded tweeter and enhanced port profile have brought about further improvements in all performance parameters.


Bass performance is equally impressive, thanks to ATC’s 12″ professional level bass driver that incorporates the company’s unique Super Linear Magnet technology. Bass, mid and HF drive units in the active model have their own dedicated and individually matched MOSFET amplifiers.


ATC’s active crossover network consists of a wide band-width, electronically balanced input stage with high common mode rejection and very low distortion.


In passive form, the SCM100 SL provides broad and symmetrical dispersion, excellent amplitude and phase characteristics throughout the audio frequency range.


Speakers are supplied with stands and fabric wrapped grills.
