A:Answer The Solo 5 is more of a sound bar where you most likely are looking to mount it. The 15 is a sound pedestal (best word I can think of) where you would not mount on wall because of depth, but would have your tv sit/stand on top of. I own the solo 5 and it's great, but got because of wall mount, but plan to get the 15 for my bedroom where it would sit on top of my media chest because I think it sounds better than the solo 5.
