Power needed
2.4–60 W
per channel, into 8 ohms
To hit 95 dB peaks at 3 m from a pair of Klipsch RP-400C, you need at least 2.4 W a channel. Anything from about 4.7 W to 60 W a channel is comfortable; past that, more watts stop buying you anything.
Power is not your constraint. The
Klipsch RP-400C 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.

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 Klipsch RP-400C specs.
