KEF's HTB2SE-W wireless subwoofer is first and foremost, a great subwoofer. The fact that it's a wireless design is icing on the cake.
The subwoofer is a round design, a mere 7.7 inches thick, and yet it still manages to go deep into the bass. When it's vertically oriented, it stands 15.4 inches tall, or if you prefer, it can be horizontally oriented.
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. I think it's one of the coolest-looking subwoofers around.
Thanks to HTB2SE-W's wireless design it can be placed anywhere in the room, but it does have to be plugged into an AC power outlet. Yes, the wireless sub has wires, but you don't have to run a cable back to your receiver or surround processor.
The KEF HTB2SE-W has a suggested retail price of $1,200. It will be shipping next month.
