it is a dedicated theatre room that is 17x13x8, completely sealed. if i do two subs, i would have to do bookshelves and put both subs in the front corner. If i do towers, i would have to place one sub in the back corner. this is 100% movies, don't care about music. Research i have done says that the bottom end on a full range tower is worthless, if you get a good sub and crossover the frequency accordingly. If i do bookshelves, it would have to have a tweeter w/ 2 drivers. am i thinking correctly on this?
