Like their smaller brother, the SCM50 ASL & 100 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 15″ 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 MOS-FET 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 SCM150 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.
