what are you experiences with rear ported cabinets...i find many stages i play, my rig ends up against the wall, which screws with the sound something awful if you have a rear ported cab. anyone ever deal with this? and wouldnt it make more sense to have that air moving forward? i really dont get it. i was just look at the new tc electronics stuff, and realized that the cabs are rear ported. this is a huge turn off to me. is that rational?
