definitely not a "sufficient power" issue, anyway. Your speakers reach 92 dB with one watt of input, one meter from the speakers. Assuming (mostly for ease of math) a huge, outrageous, impossible...

all other things being equal (and they never are) at any given SPL, driven by amps that are accurate and not audibly distorting, 2 speakers would sound the same. Of course no 2 drivers have the...

To reiterate, that's not how an amplifier works. When the amp cannot make the full power its gain calls for with a given input, the amplifier clips (distorts). Because of the way distortion works...

I don't see speaker level outputs on the sub, so to me it looks like it cannot be done. The sound has to pass through the sub's crossover and out to the speakers for the crossover to work on the...
