What amplifier does the Klipsch Klipschorn AK6 need?

Pick a speaker and tell us how loud you listen and how big the room is. We work out the power it actually needs, check which amplifiers can safely drive its impedance, and rank 293 amplifiers against it.

Your system

Four questions. Nothing is hidden on price.

Passive speakers only - a powered speaker already has its amplifier inside.
Changes the order only. Nothing is hidden for costing too little or too much.

Power needed
0.2–60 W
per channel, into 8 ohms

To hit 95 dB peaks at 3 m from a pair of Klipsch Klipschorn AK6, you need at least 0.2 W a channel. Anything from about 0.5 W to 60 W a channel is comfortable; past that, more watts stop buying you anything.

Power is not your constraint. The Klipsch Klipschorn AK6 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.

Were these amplifier recommendations useful?
It helps us tune the matching, and we read every comment.

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 Klipschorn AK6 specs.
