[QUOTE="Ampdog, post: 60552, member: 144"] To follow.... I have just thought about something else - too cold to sleep comfortably tonight ... Vaughan, I hope our differences do not lie in something simple such as the difference between a loudspeaker's [I]power efficiency[/I] and its [I]acoustical efficiency[/I]! Naturally I was writing about the latter, which was also implied in the previous formula. The power efficiency is different, i.e. simply the power consumed by the loudspeaker equivalent circuit compared to the power consumed by a resistive load of the loudspeaker value e.g. 8 ohm - the former usually being lower. This is mostly of importance only to the manufacturer. The acoustical efficiency will include the power efficiency and is the practical thing related to SPL. To try the bed again - regards. [/QUOTE]
