I have had the Genz Benz Neox 2x12 now for a few months, and right away I noticed that the bottom speaker was a little muddier than the top. It was replaced at no charge under warranty as the shop I bought it from diagnosed it as a bad speaker. Now, a couple of months later, I'm noticing the top speaker being a little distorted, and I don't think the tweeter is working at all. I've only gigged twice with it, but I rehearse with the band about one to two times a week. Does anyone else own one of these and have any problems with it? I power it with a SWR WorkingPro 700 head. This cab sounds great when it is working, but starts to sound very muddy when something isn't right.
