I have a large family room with no back wall. If I use a soundbar and sub I don't expect I'll get much in the way of surround affects. So my bigger concerns are good stereo sound for music and good, clear dialog for movies with reasonably good front stage affects. Without knowing too much about soundbar technology I was kind of thinking that a "3.1" soundbar would be best for my needs. If it has a specific center channel then I would expect it to have clear dialog from that speaker(s) and good affects from the Rand L. On the other hand it could, presumably, turn down or off the center channel for music I could hopefully get decent stereo music.
So, will any soundbar even if it only has L and R speakers give me good stereo and good dialog, or would I do better to look for one that has a dedicated center channel? I would think the latter, but since I see so few of those I'm wondering if I'm not understanding this right.
