KEF Cube 12b, very musical!
The KEF Cube 12b is a great addition to a stereo system. I have added this subwoofer to my KEF Reference 1 setup. This is not a booming subwoofer but a complimentary subwoofer that will add depth and low end to your system. The box is closed to reduce the "boom" and keep the response quick and tight. This may not be the best subwoofer for a home theater because of it's closed box design but it is fabulous for a music listening system. Don't get me wrong, with heavy bass notes or kick drum sounds this subwoofer will shake the pictures off of your walls. KEF is known for their accurate reproduction of sound and this subwoofer nails it. Add one of these to you music system and enjoy a new warmth and depth to your music.
