Power needed
24–130 W
per channel, into 4 ohms
To hit 95 dB peaks at 3 m from a pair of ELAC VELA FS 407, you need at least 24 W a channel. More than 130 W is wasted here — that is all ELAC rates the speaker to take.

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 ELAC VELA FS 407 specs.
