Power needed
30–300 W
per channel, into 8 ohms
To hit 95 dB peaks at 3 m from a pair of ATC SCM7, you need at least 30 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
- -82.0 dB effective sensitivity
- 2 dB allowed for optimistic published sensitivity
- Published sensitivity 84 dB, used as 82.0 dB per watt.

66 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.

Thanks - noted.
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 SCM7 specs.
