Power needed
20–250 W
per channel, into 6 ohms
To hit 95 dB peaks at 3 m from a pair of Dynaudio Confidence 20, you need at least 20 W a channel. More than 250 W is wasted here — that is all Dynaudio 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 Dynaudio Confidence 20 specs.
