Probably brought up somewhere else in WBF but I am still puzzled to understand, theoretically vs reality, how a 40 to 60-isch Watt SET would not get the best out of a low sensitive 85-88 dB loudspeaker?
Mathematically, and if one like to listen to let's say a sound pressure of 88dB(A) on average at a listening position that is 3 mtr away from the loudspeakers, applying p=pn + 10*log(P) - 20*log(d) , where p=dB(A) SPL listening position, pn=dB sensitivity loudspeakers, d=distance listening position to loudspeakers and P is Amp power, one would theoretically only need 30 Watt to arrive at a 91dB average loudness (88dB + 3dB headroom; doubling the power need to prevent distortion or fatigue) with 86dB sensitive loudspeakers.
Why is it that there is so much debate that relatively low power SET's would not be able to drive low sensitive loudspeakers?
