I got a great deal on a pre-Fender SWR Goliath Sr. cab ($375) I had ordered from another store at GC and there's a minor issue. I picked it up yesterday and once I got it home and unpacked it, it looked good, I plugged it in and played through it for 15 mins and everything sounds great (or so I thought… One of the drivers (of the 6) vibrates sympathetically with EVERYTHING. I didn't notice it at first, then at lower volumes I heard it buzzing (while I was playing through it). I then unplugged the cab to play through an 8x10 Carvin I had in my space to make sure it was the cab and not my head (Boogie 400).... and the 1 SWR 10" still buzzed the same when it was unplugged and I was playing through a different cab. This is pretty much at all frequencies. I have a 100W 15” Ampeg combo, played that and the SWR driver buzzed on the other side of the room, even at low volumes. I pulled the speaker, inspected it, checked it w/a DVM, all looks just fine (dust cover and surrounds are well intact, DVM read 8 ohms as it should) and the driver sounds fine other than the damn buzzing. No loose dust cap or tears in the surround, I'm stumped. So.., now I need to decide. Do I simply take it back to GC and get my $$ back w/their 30 day cash back guarantee or do I buy a re-coned speaker of the exact model that's causing the issue for $70, pushing the total cost of the cab up to $450?? Would GC pay the $70 for the re-coned speaker or give provide a current Eminences currently used by SWR? What would you do?
