    Have a couple of Yamaha C112 Vs that we use as monitors. They had some pretty nasty distortion at all levels...I replaced the drivers and the diaphragms in the horns and I'm still getting distortion. What else could it be? Would xover damage cause distortion like this? I tried them with different amps and new drivers...what else should I troubleshoot?

    yes that is very possible...would be my guess, especially since you have replaced the drivers etc...

    Thanks...is this something that can be successfully repaired or would it be better to just replace the xover outright?

    Check your cab for air leaks

    Check for loose hardware

    Did that. It's really bad distortion. Worse than loose hardware.

    Have you tested the drivers independent if the crossover?

    No signs of toasting on the xovers. Going to test the drivers on their own this week sometime.

    Stupid question: you've subbed in known-good speakers in place of the Yammies to check that the distortion isn't in the upstream signal path, yes?

    Yes. Other cabs were subbed in place of these with no issues.
