[QUOTE="Norval, post: 73912, member: 62"] I'm a little hesitant to answer, since there are real guru's here on the forum, and that's not me. But NO, you will have to measure the voltage over the speaker terminals into a constant resistance of say 8 ohm's, with a sine wave on the input. You will then have to increase the volume till max (I guess just before clipping ??? ), and measure the voltage across the terminals. I like the idea to do this in 8 ohms and 4 ohms, and some manufacturers does it even in 2 ohms. But beware, if you have an 100W amp, the resistor must be able to dissipate the power. That's why weight is important to me. A 100 VA transformer is much lighter than a 1000VA transformer. :) [/QUOTE]
