Thank you, Bill! So you would recommend me going with the 12" and 15" in tandem instead of going with 2x 12"? For sub #2 (the one by the couch) where should the opening of the speaker point? Towards the couch? Towards the TV? Or towards the open room? I'll have sub #1 facing towards the couch, of course, not sure where the second one should point, or if it even matters.
