yeah, I just didn't think it'd happen with the Alpha's.

He is really going for max output, so parallel to series is a 6db hit.. final resort, if it even helps.

The cabinet is already built, no room for a compression driver, really.

Hmm... how about a second order low pass right when the piezos come in around 4k?

I read all of the previous posts about it... good info. I hope I find a solution.
