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.
Product Features
- 3 x Class A/B MOSFET amplifiers, 200W bass, 100W mid & 50W high frequency
- User adjustable input sensitivity & bass shelf controls
- Balanced input & 2nd order Linkwitz-Riley active crossovers
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. ATC's 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.
These loudspeakers are also available in PASSIVE versions. Please see this link to the SCM50PSL.
Both versions employ ATC’s renowned drive units which are painstakingly designed and manufactured by ATC in the UK.
ATC is committed to not only ensuring that there product range offer nothing less than the best sound reproduction money can buy they're also committed to housing their stunning engineering is as bespoke a manner as possible.
