I know this has been asked probably hundreds of times before but I never looked cuz I was never interested. I'm a bass geek, far from an amp geek but working hard at it. Talking strictly combos here, what's the difference btwn 2X10s and 1X15? Specifically: Will one handle a B better than the other? Will one handle more volume than the other? Will one distort more quickly? Will the 15 give more bottom? Will the 2 10s sound a lot thinner than the 15? I'm very close to ordering one of the new Fender 250s, and wanted a 15, but it seems only the 2X10 models are currently available anywhere. All thoughts are welcome. Thanks.
