Debut 2.0 B6.2

Headroom Notes

The 87 dB figure is quoted at 2.83 V / 1 m into a 6-ohm nominal load. 2.83 V across 6 ohms is 1.33 W, not 1 W, so the true one-watt sensitivity is about 1.2 dB lower — roughly 85.8 dB. That gap is invisible when this speaker is put in a table next to an 8-ohm rival quoted the same way, and it is the usual reason a Debut sounds quieter than its spec sheet suggests.

Amplification Warning

ELAC publishes no minimum impedance for this model — only the 6-ohm nominal and a 120 W maximum input. Without a published dip, the honest planning assumption for a 6-ohm two-way with a 2.2 kHz crossover is that the real minimum sits below 4 ohms somewhere in the bass.
