Hello Talkbass. From what I've seen, you're all helpful folk, and I hope you'll help me out with a decision I need to make. I'm in a Christian alternative band, (we're all in high school), and my guitarist is pushing through a Marshall head with a Behringer stack (his family is ridiculously rich), and all I have is a Behringer BX1200 120 watt combo amp. The head part of it is good, but the speaker gives me a strange sound when I start pushing it. I don't think the speaker they equipped with it can't handle the amp. Nonetheless, I'm interested in getting a cabinet, but possibly keeping the amp and using the cabinet as an external speaker (it can do that). This sounds good in theory, but there are a few problems I have. One is that I have no idea what type of cabinet I want!! Another is that my combo amp is 48lb, and a beast to haul around. I don't want to get a head just yet, but when I do, it will be a Behringer BX3000T 300 watt RMS head. Right now, I'm focused mostly on getting a cabinet, but I need to make sure that it can handle the BX3000T when I get it! I'm on a budget, I don't want to spend more than $350. I appreciate it!
