My buddy's got two 12" Audiobahns facing inwards on a sealed box, and we haven't heard them yet because he has no amp. Are these going to sound like crap? I don't have the specs on the box though.
sorry to say they'll sound like crap cause they A bahn. Abahn not really known for how well they sound. Inverting subs won't make any difference in sound but you may want to consider that the overall enclosure size has changed since the sub is not taking up space which may or may not effect the sound.
it only changes the tuning of the box so it can either sound good or sound bad...also it has no effect on the subs output.....its really also used to show off the magnet...
