Power needed
3.8–60 W
per channel, into 8 ohms
To hit 95 dB peaks at 3 m from a pair of Klipsch RP-500M, you need at least 3.8 W a channel. Anything from about 7.5 W to 60 W a channel is comfortable; past that, more watts stop buying you anything.
Power is not your constraint. The
Klipsch RP-500M is efficient enough that essentially any
amplifier we list will drive it at this level. Choose on inputs, streaming, phono
stage and price instead — and if you like valve amplifiers, this is a speaker
that suits them.

57 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.

Good match
13 dB of headroom, far more than needed. No harm in it.

Excellent match
9 dB of headroom - enough, but at the modest end for this speaker, which takes up to 60 W.
Has a 8 ohm tap, which is exactly what this 8 ohm speaker wants. Taps: 4 / 8 ohm.
A valve amplifier makes the same power on each tap, so what matters is sensitivity - and at 91.0 dB this speaker is efficient enough that 28 W is comfortable.
Balanced against the price of the speakers.

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 Klipsch RP-500M specs.
