Power needed
15–200 W
per channel, into 8 ohms
To hit 95 dB peaks at 3 m from a pair of KEF R5, you need at least 15 W a channel. More than 200 W is wasted here — that is all KEF rates the speaker to take.
Show the working
- 95 dB target at the seat
- +4.8 dB for 3.0 m of distance
- -3 dB for a stereo pair
- -85.0 dB effective sensitivity
- 2 dB allowed for optimistic published sensitivity
- Published sensitivity 87 dB, used as 85.0 dB per watt.
Advance Paris A10 APEX with the KEF R5
Workable with care
9 dB of headroom over what this speaker needs - peaks stay clean.
Rated to 4 ohms, but this speaker dips to 3.2. Fine at sane volume, tight if you push it hard.
Power rises usefully into 4 ohms (120 W to 185 W).

Excellent match
11 dB of headroom over what this speaker needs - peaks stay clean.
Rated down to 2 ohms - stable into anything this speaker will throw at it.
Power nearly doubles into 4 ohms (200 W to 400 W) - a stiff supply that copes with hard loads.
Costs more than the speakers - worth it only if you plan to upgrade them later.

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 KEF R5 specs.
