## About

The active SCM40 — a sealed three-way with ATC's 75 mm soft-dome midrange, driven by 242 W of on-board Class A/B tri-amplification (150 W bass, 60 W mid, 32 W treble) and active crossovers. Balanced XLR input with overload and DC fault protection: a studio main in a domestic floorstander.
