KEF HTB2 subwoofer
When it comes to subwoofers, style and deep bass performance rarely go together. Most of the great subwoofers are big, cube-shaped things, but KEF's engineers didn't get that memo: the HTB2 ($799) is round, a mere 7.7-inches thick, and still manages to go deep into the bass. It's a vertically oriented design, standing 15.4-inches tall, which might make it easier to place in your home theater than a cube-shaped model would be. If you prefer, it can be placed horizontally instead.
The subwoofer sports front- and rear-mounted 10-inch woofers. However, only the front woofer is powered by the 250-watt onboard digital amplifier--the rear woofer produces bass passively, motivated by the internal air pressure created by the movement of the front woofer. Build quality is exceptional, and the HTB2 is available in two finishes, high-gloss black and high-gloss silver, to match the respective colors of KEF's FiveTwo and Home Theatre series speaker systems. We think the HTB2 is one of the coolest-looking subwoofers around, but we also have to point out that the woofers are exposed. KEF doesn't provide grilles to cover them, so don't place these beauties any place they would be vulnerable to wear and tear from kids or pets.
