I currently have an Ampeg B2R, going into a Backline 410. I wan't to replace the cab with two Avatar cabs, I know I want a 210, probably the neo. But I'm not sure about the second one, I was thinking a 212 neo. My thinking behind this is that, running two 8ohm cabs will give me some more power and volume now, and when I get a new, more powerful head, that Avatars will still be able to handle the load. Do I have this backwards? I guess what I'm asking is, is it "safe" to do this?
