I am in the process of finishing my basement. I want to set up a 5.1 system I already have, but, my surround speakers are rather large bookshelfs, and are getting hard to place. As the framing is not yet done, I thought of mounting them in the ceiling, downfiring, before the drywall goes up. The speakers are all RBH Signature. 1044se for the fronts, 3 441se for the surrounds and center, and a 1010sep sub. Is this viable option, or should I just get different in ceiling surrounds?
