Buying the KEF HTF8003 is an expensive proposition once you add the cost for an AV receiver and subwoofer, but it has some of the best sonics we've heard from a sound bar.
Single-speaker sound bar; excellent sound on movies for a sound bar; stylish exterior design; KEF offers matching bookshelf surround speakers; relatively light weight makes wall-mounting easier
Needs a separate subwoofer for credible home theater sound; no virtual surround effects; rubber support pads are too small; needs to be carefully tweaked to get the subwoofer/sound bar balance right; requires an AV receiver
