Headroom Notes
88 dB at 2.83 V on an 8-ohm nominal, so the figure doubles as dB/W/m without correction. The recommendation to use is 40–150 W into 8 ohms; the parallel 75–300 W figure is quoted into 4 ohms, which is not this speaker's declared load.
Amplification Warning
Monitor Audio prints the impedance minimum together with the frequency at which it occurs — «4.4 Ohms @ 38 Hz» — which almost nobody else does. Knowing the dip sits at the port tuning frequency tells you it is a bass-region load, met at high excursion and high current. 4.4 ohms on an 8-ohm nominal is a mild dip by the standards of this batch.
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.
«Recommended Amplifier Power (RMS, Music Signal) 75 - 300 W into 4 Ohms / 40 - 150 W into 8 Ohms»
The same table declares the speaker's nominal impedance as 8 ohms and then recommends amplifier power at two load impedances, one of which the speaker is not. The 4-ohm row describes what an amplifier delivers into a 4-ohm load, not what this speaker presents; read against the 8-ohm nominal, the two rows are the same amplifier described twice. Taking the larger pair of numbers as this speaker's power requirement overstates it by roughly a factor of two.
