So I've been doing research on Cabs/Amps recently. I currently own an Ampeg 2x10 that's GREAT for rehearsals, but I'll obviously need more than that for gigging. Practically, I don't think I want to go over a 4x10. I've listened to quite a few different brands and have begun to focus on the Markbass 4x10's, but I've noticed they come in both front ported and rear ported versions. Same cost, same output, same everything for the most part. That made me wonder...: How do rear ported cabs and front ported cabs differ? Is there much of a difference, or is it more of a stage setup preference? Is one version boomier than the other? Does one over heat or handle more voltage than the other? Noob question, yet again. I'm learnin... Thanks much.
