Power needed
15–235 W
per channel, into 8 ohms
To hit 95 dB peaks at 3 m from a pair of SVS Prime Tower, you need at least 15 W a channel. Anything from about 30 W to 235 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 SVS Prime Tower specs.
