My living room has a vaulted ceiling, 13 feet tall at the highest point. I'm thinking of putting a pair of 632 LR speakers on a ledge underneath this high point, about 9 feet from the floor, with a sub woofer on the floor. Can you tell me what kind of sound I can expect? Musically speaking, will it fill the room, or will sound be lost with the speakers being so far above ear level?

Thanks!
