[quote name='Mr. Foxen' post='923825' date='Aug 13 2010, 01:22 PM']Listen to each speaker and see if one is complaining a bit more, if one is a bit duff, it can throw the tuning of the rest out and cause upset. Does the head have a line out? There is a Matamp Quasar power amp in an MDF box at RS that is mine, if you are still there. Run the pre into that, into the cab, you should have a bit more headroom, plus LED indicator to tell you how close to clipping the amp is, it is very neutral voiced, and recently tested so it outputs the full 500w from one side at 4ohm. Should be able to figure if its amp of cab being upset that way.[/quote]
Yes mate, we're in RS tonight. If you dont mind me doing that, I'd appriciate it, as it should make it pretty clear cut if the cab is indeed the culprit.
The cab sounds fine at lower volumes - I'd imagine a duff speaker would be apparent all the time?
