Headroom Notes
91 dB at 2.83 V / 1 m looks like the most sensitive speaker in this batch, and on paper it is — but on a 6-ohm nominal load 2.83 V is 1.33 W, not 1 W, so the equivalent dB/W/m figure is about 1.25 dB lower. Compared like for like against the 8-ohm KEF and B&W here, the real gap is smaller than the printed numbers suggest.
Amplification Warning
Q Acoustics does not print a nominal impedance for this speaker at all — the row is «Average Impedance: 6 Ohm», a label the company's own 5000-series pages replace with «Nominal impedance». We store 6 Ω because that is the only impedance figure offered besides the 4 Ω minimum, but an average and a nominal are not the same quantity and the sheet never says which averaging was used.
What the datasheet actually says
Quoted verbatim from the manufacturer’s own page, with the date we checked it. We state what is printed, not what anyone intended by it.
«Average Impedance: 6 Ohm»
On the 3000i pages Q Acoustics calls the impedance «Average Impedance»; on the 5000-series pages of the same site the corresponding row reads «Nominal impedance». The two terms are not interchangeable: a nominal impedance is a declared load class (IEC 60268-5 ties it to the measured minimum), while an average is a computed mean whose method the sheet does not disclose. Anyone comparing a 3000i against a 5000 is comparing two differently defined numbers printed in the same column position.
