Speaker specs: Sensitivity, & Amp match

I'll eat my shorts if I'm wrong!

Elvick, I think you are safe - the word is percieved and we all percieved differently. Your post coincides with my perception, therefore you are right! :-)

S7horton is correct:)! 6db (spl) *is* "twice". Elevick: You show this yourself quite explicitly, above: As change in spl relates to w change^2, 2x as loud requires 2^2=4x watts. Every 6 db you clearly show x4 watts. Cheers!

Gregm, I think I'm getting confused! As I understand it, a doubling of power results in a (measured) 3db response in sound from a speaker, but the 3db, or even 6db, increase in volume isn't necessarily "percieved" by the listener as a "doubling" in volume. From what do you conclude the 6db increase in volume results in a "percieved" doubling of volume to the listener?

I smell this thread getting caught up in semantics.

But I do "percieve" myself having twice as much fun reading it than anyone else......:-)
