What amplifier does the Aperion Theatrus T65 Speaker 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 292 amplifiers against it.

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.

per channel, into 4 ohms

To hit 95 dB peaks at 3 m from a pair of Aperion Theatrus T65 Speaker, you need at least 6.0 W a channel. Anything from about 12 W to 95 W a channel is comfortable; past that, more watts stop buying you anything.

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 Aperion Theatrus T65 Speaker specs.
