Power needed
24–300 W
per channel, into 8 ohms
To hit 95 dB peaks at 3 m from a pair of ATC SCM20PSLT, you need at least 24 W a channel. More than 300 W is wasted here - that is all ATC rates the speaker to take.
Show the working
- 95 dB target at the seat
- +4.8 dB for 3.0 m of distance
- -3 dB for a stereo pair
- -83.0 dB effective sensitivity
- 2 dB allowed for optimistic published sensitivity
- Published sensitivity 85 dB, used as 83.0 dB per watt.

67 power amplifiers that would also drive them
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.

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 SCM20PSLT specs.
