Beef up movies and music
British hi-fi audio giant KEF knows a thing or two about making great-sounding loudspeakers. So it should come as no surprise that the company's audio expertise extends to powered subwoofers, too. The KUBE 10b delivers hard-hitting bass for music, movies, and video game soundtracks.
A rear-panel "location switch" optimizes the bass output to match where you've placed the sub.
Intelligently designed components
The KUBE 10b is outfitted with a custom-designed 10" 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. Use this sub with confidence in a small- to medium-sized room.
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.
