Is my amp the problem?

I recently decided to bi-amp my speakers so I purchased a crown xls 1002. (225w 8 ohm). I am driving a 10 woofer. It sounds horrible. I can't seem to get it to put out much power despite its rating even when I make all the right adjustments. Its a class D amp. Is that my problem? It just doesn't seem to have any Ba**s. Lol. Advice is appreciated.

If you are using miniDSP, can we hope this means you have the ability to measure your response? Most likely it's an EQ problem, or sensitivity mismatch.

I use OmniMic, but Room EQ Wizard also works.

So can we assume you have bypassed the internal crossovers and replicated them in miniDSP?

That's usually the easiest way to go. Test 1 driver with the passive crossover. Adjust miniDSP until your active filter looks the same. Repeat with next. Make sure your sensitivity matches before and after.

Best,

Aux,

Um, no.  I meant, the miniDSP can be miscalibrated for the speaker. They sound good enough. What you need are measurements.

Based on that, I'd say your biggest problem is lack of measurements.

Don't change any hardware. Get Room EQ Wizard and a Dayton imm6 microphone ($25, calibrated) first.
