Sound bar speakers generally only appeal to a small portion of home audio buyers. If you've got a large budget, minimalist ethos, appreciate sound quality--but not enough to insist on a pair of standalone speakers--a sound bar speaker fits your niche.
The KEF HTF8003 doesn't offer anything radically different from the competing models available, with a long tubelike design and glossy black finish. Its sound quality with movies was among the best we've heard on sound bars (although it doesn't do any virtual surround effects), but music fans will want something more substantial.
As usual with this product category, our major concern is the total cost of the system: in addition to the sound bar, you need an AV receiver, plus we found that a subwoofer is pretty much a must-have, too. That will probably bring the total cost to over $2,000, which could buy you a lot more sound quality from a more conventional tower speaker arrangement, but if you need the single-speaker style, the KEF HTF8003 is one of the better options available.
