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.
