ATC SCM50SLT
Overview
The SCM50 ASLT (active) and SCM50 PSLT (passive) towers are designed to offer exceptional performance and enjoyment to the home hi-fi enthusiast and music lover.
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 SCM50PSLT provides broad and symmetrical dispersion, excellent amplitude and phase characteristics throughout the frequency range.
