Headroom Notes

Nubert is the rare manufacturer that publishes both sensitivity scales side by side - 'Wirkungsgrad (2,83V/1m) 86,5 dB' and 'Wirkungsgrad (1W/1m) 83,5 dB' - and the pair is self-consistent: on a 4-ohm nominal, 2.83 V is 2 W, worth exactly 3.01 dB, and the two printed figures differ by 3.0. Where a maker gives both and they agree, there is nothing left to guess at.

Amplification Warning

'Impedanz: 4 Ohm', stated plainly and without a compatibility hedge. Among the German brands in this batch only Nubert and ELAC do that; Teufel, Canton, Magnat and Heco all print a 4-to-8-ohm span instead.
