[QUOTE="mat3833, post: 8787753, member: 587645"] That is very much an oversimplification. Double the power doesn't really equal a 3db gain after power compression and heat losses. Yes a 15 will often have a higher efficiency, but the reality is subwoofer efficiency a joke. It's measured at a frequency that they don't even play. Surface area doesn't mean anything. Effective displacement matters. A 15 will have roughly the equivalent displacement of 2 10" or 1.5 12" subs of equal Xmax. I'm an advocate for putting as much cone area as you can into the space you have available. Adding power is pretty easy, re-building an enclosure not so much. Matt [/QUOTE]
