I need a 4-Ohm 1x15 cabinet. I have a Peavey Bam 2x10 combo that sounds great on it's own, but I want to get the full 500 watts @ 2 Ohms. There are not many choices of 4 Ohm 1x15 cabs out there. Any suggestions? Peavey has a Pro 2x10 cabinet 350 watts @ 4 Ohms, which would probably match up well, but I really want a 1x15 cab.
