So I was back to square one and with using the 4.0 I upgraded to a certain level. The polk's didn't really hold up to the power that they were receiving. Kind of disappointing. They sound like they had a rev-limiter built in. Maybe it was the crossovers. Because the CV's handled the 4.0 with no issues at all. I still have 1 set of CV PA's left and they will handle 400 watts pretty well.
Looking to find some speakers that can really handle 500 watts per channel or more. Ideas please!!! And I dont want to have to have a sub to get all the bass I want.
