24–375 W
per channel, into 8 ohms
To hit 95 dB peaks at 3 m from a pair of ATC SCM50PSLT SE, you need at least 24 W a channel. Anything from about 47 W to 375 W a channel is comfortable; past that, more watts stop buying you anything.

Sensitivity and impedance figures are the manufacturer's own. We read sensitivity as dB at 2.83 V/1 m and take 2 dB off it, because published figures run high. Treat the result as a well-founded starting point, not a measurement. Full ATC SCM50PSLT SE specs.
