[QUOTE="David Morison, post: 100570, member: 2076"] Re: More spec sheet nonsense It's the upper of the two spec's I flagged that's wrong, not the bottom. 101dB is an efficiency of approximately 8% (if that were from one Watt input, obviously the impedance curve affects this somewhat), so 400W electrical[I] input [/I]should result in a ballpark [I]output[/I] of 35 acoustic Watts, not 400W. There's also a very slight misrepresentation of the frequency range apparent when comparing the quoted range with the graph on the spec sheet. The max level on the graph is 105dB at approx. 310Hz and 1.8kHz, so if that's the top of the +/-3dB range, then the bottom of the +/-3dB range should be where the curve drops through 99dB. That point looks to me to be about half an octave above the 113Hz on the specs. [/QUOTE]
