Man, I haven't gotten a sound bar setup at home since they stopped making TVs that had the sound go on them after a few years, and that's in the days of CRT TVs!
Anyways, as far as Sound bars go, I often suggest just using a decent quality Home Theater system if you have one over the Sound Bars. The Home Theater system gives better sound quality especially if you have HDTV Service at home and use Optical Audio Out from a Set Top Box or a TV to your Receiver. As long as the speakers you have for the Home Theater aren't tiny things with no base or mids with a single sub to do all the work, I prefer that method. At home since the HDTV has tiny speakers at the bottom of the panel since the display is so thin, the speakers don't exactly kick up a lot of base or mids. The TV has a small sub in the center of it which produces some Mids, but it doesn't do a lot. I have a Home Theater system I built using 5 Bookshelf speakers from Infinity (the same company, Harmon Kardan who makes JBLs) which are mounted on the wall, each having their own mid/sub/tweater, and a subwoofer for the all encompasing sound. I use a Denon receiver capable of powering the speakers and the sub, and it has Optical Audio coming from anything that supports it, such as my DVD Player (Don't use Blu-Ray yet due to DRM hatred), a Home Theater PC, and Satellite Receiver. We don't have HD service so no 5.1 audio for us, but the sound quality for a slightly more expensive setup is just awesome. Sounds more natural and realistic, not to mention soothing based on the medium.
