so I read that thread about vertical stacking, and it does make sense. BUT, heres the deal, Have you ever seen/heard of people taking 2 cabs that would not stack well together if they were vertical? for instance, i just made a post about purchasing a 2x10 to go with my 15 I would not stack a 2x10 vertically on my 15, but if I put it on the Side of the 15 it may sound better than laying it horizontal on top of it? Id like to hear some input on that. allthough, If i stacked my 210 on a 15..i could attach some type of very cool beer holder on the empty spot of the 15! that could be interesting!!
