Power needed
6.0–95 W
per channel, into 8 ohms
To hit 95 dB peaks at 3 m from a pair of Revel PerformaBe F328Be, you need at least 6.0 W a channel. Anything from about 12 W to 95 W a channel is comfortable; past that, more watts stop buying you anything.

- 95 dB target at the seat
- +4.8 dB for 3.0 m of distance
- -3 dB for a stereo pair
- -89.0 dB effective sensitivity
- 2 dB allowed for optimistic published sensitivity
- Published sensitivity 91 dB, used as 89.0 dB per watt.
Accuphase P-4600 with the Revel PerformaBe F328Be
Excellent match
14 dB of headroom, far more than needed. No harm in it.
Rated down to 2 ohms - stable into anything this speaker will throw at it.
Power nearly doubles into 4 ohms (150 W to 300 W) - a stiff supply that copes with hard loads.
A power amplifier: you will need a preamplifier, or a streamer with a volume control, as well.

Excellent match
11 dB of headroom over what this speaker needs - peaks stay clean.
Has a 8 ohm tap, which is exactly what this 8 ohm speaker wants. Taps: 4 / 8 ohm.

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 PerformaBe F328Be specs.
