[QUOTE="headless, post: 5343471, member: 566363"] Running 2x12db x-overs @ 100hz does not equal 1x24db @ 100hz. For example, a 12db per octave x-over that reaches -3db @ 80hz (that's the crossover point) starts cutting frequencies 1/4th of an octave above 80hz - thus 1 octave = -12db, or 1/4th of an octave = -3db. A 24db per octave crossover only needs to start cutting frequencies 1/8th of an octave above it's crossover point. Thus 2x12db crossovers would actually give you a totally skewed x-over point (-3db) that isn't actually where you set the crossover point at all. Sure, you might like how it sounds.... and i'm sure you could even graph/calculate the new x-over point...but if this guy has 2x12db x-over's @ 100hz, he's probably got a HUGE hole in response, especially considering his sub is crossed twice @ 80hz so is doing the same thing on the other side of the spectrum.
