Design and features
The KEF HTF8003 looks like most of the other sound bars on the market, with a long tubelike design and glossy black finish. Viewed from the side, the HTF8003 has a skinny, oval-shaped profile, and it comes to only 3.2 inches deep. The speaker isn't particularly heavy, but its weight distribution made it feel somewhat unstable: whenever we moved HTF 8003, it had a tendency to tip over backward. The problem: the small rubbery support pads seem a little too small to provide a stable platform for the speaker. On the plus side, the HTF8003 weighs significantly less than the competing Atlantic Technology FS-7.0; we'd feel much more comfortable wall-mounting the HTF8003 ourselves.
Around back, the HTF8003 has three pairs of all-metal spring connectors that accept bare wire ends, or wires terminated with pins or spades; banana plugs won't fit. We appreciated that they weren't recessed into the speaker, like on the Canton CD 90 SB, but their low positioning made them slightly difficult to access with speaker wire.
Behind the speaker grille, the HTF8003 houses nine total drivers. Each channel includes a 3-inch Uni-Q driver (and each Uni-Q driver has its own high-frequency/midrange/bass driver), a 3-inch woofer and 3-inch auxiliary bass radiator.
Since the HTF8003 doesn't make much bass on its own we started our listening tests partnering the speaker with a KEF HTB2SE-W wireless sub. We've tested the wired version of the sub before, and know it's a great-sounding unit. But in this case we had to work for hours to get the HTB2SE-W to blend with the HTF8003.
