I've pretty much decided to replace my Ampeg BA-115 with Behringer Bx3000t head and a single cab, but I can't decide whether to get an Avatar 1x12 w/tweeter or the Avatar compact 1x15 w/tweeter. I'm planning on getting an 8 ohm cab, so I can add another cab later, probably an Avatar 2x10. I play just about everything from acoustic to metal. I'm leaning toward the 1x12, since it would probably have more definition and punch than the 15. Plus, it's smaller and cheaper. Any suggestions would be appreciated.
