Power needed
32–150 W
per channel, into 6 ohms
To hit 95 dB peaks at 3 m from a pair of Revel Performa4 M145, you need at least 32 W a channel. More than 150 W is wasted here - that is all Revel rates the speaker to take.

- 95 dB target at the seat
- +4.8 dB for 3.0 m of distance
- -3 dB for a stereo pair
- -81.8 dB effective sensitivity
- 1.2 dB taken off to convert the 6 ohm 2.83V rating to dB per watt
- 2 dB allowed for optimistic published sensitivity
- Published sensitivity 85 dB, used as 81.8 dB per watt.

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 Revel Performa4 M145 specs.
