47–140 W
per channel, into 4 ohms
To hit 95 dB peaks at 3 m from a pair of ELAC Uni-Fi BS U5 Slim, you need at least 47 W a channel. More than 140 W is wasted here — that is all ELAC rates the speaker to take.

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 ELAC Uni-Fi BS U5 Slim specs.
