I bought a used Genz-Benz XB2 (4x10 cabinet) to plug my new Genz-Benz Shuttlemax 9.2 into. All was going fine, played a great gig with it. I'm in a Grateful Dead cover band so I had this thing turned up to about 2. Like I said gig went great. One week later I plug it back in in my basement, and I've got at least one shot speaker and the low end is full of blown speaker noise. This was gonna my baby! The question is... did I buy a bad cabinet and one gig blew it out... it was fine before the gig.... Or is this a bad match of head and cabinet and I blew the cabinet? I can return the cab within 30 days for store credit, so I'm not terribly concerned, but its a real head scratcher. It sounded wonderful!
