Anyone here using the Aperion 10 inch sub? How much of an upgrade is it over the 8inch? I have the 8" currently running in my apartment (room size 12x22x9 ft.); while I do like the sound especially for music, I am trying to decide whether to upgrade to the 10". Will the 10" perform as well as the 8" for music? For HT I would imagine that the 10" would perform much better.........I am 50/50 music/movies.........any advice would be much appreciated!
