Atmashpere, how would one ever test that variable independently outside of other amplifier qualities? Plenty of seasoned audiophiles and reviewers alike that would argue subtleties in how a woofer is damped is second only to an amps ability to provide current into load variance in determining the best match.@petland Actually its pretty easy to determine if a woofer or other driver is overdamped with a fairly simple circuit. An amplifier does not need to be involved. This was demonstrated by the chief engineer of Electro Voice back in the late 1950s (it was EV and MacIntosh that led the way using the voltage rules for driving speakers). The physics of course hasn't changed since then.
