What amplifier does the ATC SCM50PSL need?

Pick a speaker and tell us how loud you listen and how big the room is. We work out the power it actually needs, check which amplifiers can safely drive its impedance, and rank 196 amplifiers against it.

Your system

Four questions. Nothing is hidden on price.

Passive speakers only — a powered speaker already has its amplifier inside.
Changes the order only. Nothing is hidden for costing too little or too much.

per channel, into 8 ohms

To hit 95 dB peaks at 3 m from a pair of ATC SCM50PSL, 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.

Listed separately because they are not a complete system: a power amplifier has no volume control and no inputs to speak of, so you need a preamplifier or a streaming preamp as well. Worth it if you already own one, or if you want to buy the two halves separately.

Were these amplifier recommendations useful?
It helps us tune the matching, and we read every comment.

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 SCM50PSL specs.
