well if you look at it like that, the solobarics would be more than what they say they are too, the diagonal across the square is way more than 12" (or whatever) inchesthen you would no longer have a 12" sub it would be 12.5 or something crazy like that which still doesnt get over having a gooberish surround
so i gues you don't:anything square sucks. more prone to braking.
