Solid bass with a compact footprint
KEF knows how important great bass is when you're listening to tunes or watching a movie. They've designed the KUBE 8b powered subwoofer to provide excellent low-end performance without taking up a lot of space on your floor. This compact sub is an excellent choice for small- to medium-sized rooms where space is at a premium.
Intelligently designed components
The KUBE 8b is outfitted with a custom-designed 8" woofer, and a powerful 300-watt RMS amplifier. KEF designs and builds all of their components in-house to make sure that both the quality and audio performance are up to the company's high standards.
Built-in sound controls
On the back panel you'll find a simple-but-useful input and control panel. My favorite feature? You can choose from three placement presets (free-standing, in-cabinet, or corner) to dial in the sound based on where the sub is located in your room.
