Ok !!! that’s something I didn’t know, but my question is pointed in another direction: Wee are comparing two speakers with the same parameters except the power handling. Why I need too by a speaker with more power and pay it more, when I can by the same speaker with less power handling capability, which means less money spend for the amplifier. (Ok, the answer is probably: so don’t by and save the money), but that is not what I am talking about. Lets rephrase my question: Why people give money for some speaker that has power of 1000 W and SPL = 100 dB, when they can by a speaker with let’s say 200 W and SPL 100 dB. Ok you haw sad because the compression, but for the speaker of 1000 W I will probably use amplifier which gives 1000 W and for 200 W speaker I will use amp. Of 200 W, because I can’t drive 1000 W speaker with amp. of 200 W.( I can but efficiency is greatly reduced). I want too tell that the speaker will go into compression when it is driven in full power and it is not a meter of power handling. So what is the difference?
