I ended up bringing the JL back. I have a DC360.4 that I was having a problem with but it's at Zapco now and I'm just going to wait for it. It's a great amp -- seems crazy to ditch it.

Technic, I would love to know what frequency (and at what Q) you are notching that gong out at if you don't mind sharing.
