I have a pair of Infinity SM152 speakers and one of the 15" woofers is blown
and I'm trying to find a replacement driver. A new OEM driver is over $300
(CAD) so I am trying to find a generic speaker that will work. I've tried a
few already but they are not as effecient and the bass end up sounding very
weak from one side.

Does anyone have the specs for these old monsters? Specifically the wattage
rating and the SPL. Frequency response would also be helpfull

TIA
