The KEF Kube8b is a small but powerful subwoofer. The subwoofer is only 29 centimeters wide and high, so you can simply place it in or on a cabinet. This makes it suitable for placement in small living rooms. The subwoofer produces a fast, clear bass that enhances different styles of music and movie sounds. Thanks to the closed casing, the low frequencies sound even better. With the wide range of different inputs and settings, you can easily adjust the subwoofer to any placement in the room. Combine the subwoofer with speakers and a center speaker for a home cinema experience.
