Power needed
1.9–60 W
per channel, into 8 ohms
To hit 95 dB peaks at 3 m from a pair of Klipsch RP-5403C, you need at least 1.9 W a channel. Anything from about 3.8 W to 60 W a channel is comfortable; past that, more watts stop buying you anything.
Power is not your constraint. The
Klipsch RP-5403C 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.
Show the working
- 95 dB target at the seat
- +4.8 dB for 3.0 m of distance
- -3 dB for a stereo pair
- -94.0 dB effective sensitivity
- 2 dB allowed for optimistic published sensitivity
- Published sensitivity 96 dB, used as 94.0 dB per watt.
Schiit Vidar 2F with the Klipsch RP-5403C
Workable with care
17 dB of headroom, far more than needed. No harm in it.
This amplifier does not publish a minimum impedance. An 8 ohm speaker is a safe bet even so.
Power nearly doubles into 4 ohms (100 W to 200 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.

No 4 ohm power rating on file. On a 8 ohm speaker dipping to 3.4 that is the figure that matters, so this one is unproven on the load.
Balanced against the price of the speakers.
Showing the best 20 of 224. Narrow it with the price range below, or a different budget split.
68 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.

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-5403C specs.
