[QUOTE="Rob Timmerman, post: 148047, member: 172"] Re: Speaker protection Better make sure your voltmeter measures properly in the passband of your loudspeaker, as many aren't all that accurate above ~400Hz (or even lower in some cases). Note also that a true-RMS voltmeter will measure the equivalent heating voltage of the clipped square wave, while a non true-RMS meter will assume a sine wave (at lower power for the same peak-peak voltage) [/QUOTE]
