Enhance the Sound and Feel of Your Music (and Movies), Enjoy Freedom of Placement: Dynamic-Sounding KEF KUBE 8b Subwoofer Soars with 300-Watt Amplifier and Custom-Integrated Parts

Impressive power, immersive detail, fluid integration, easy setup, and in-house-assembled internal and external parts: The KEF KUBE 8b offers practically everything – and then some – anyone could hope to want from a subwoofer of its size and price class. Whether adding it to KEF's LS50 loudspeakers, complementing a computer-audio system, or using it to round out a small-to-medium-sized home theater, KUBE 8b delivers dynamic, accurate, and coherent sound that will enhance any music or movie you play. KEF's Intelligent Bass Extension (IBX) algorithm – which creates an extended depth that unleashes the full potential of the custom-integrated eight-inch driver inside KUBE 8b – assists a 300-watt amplifier and 56-bit MIPS DSP preamplifier to offer arresting sound. A range of LFE, line-level, and speaker-level inputs augment Phase selection and three DSP-controlled EQ settings for optimal configuration with any room or system. Backed by our 100% Music Direct Satisfaction Guarantee, KUBE 8b is a mini marvel that will change the way you hear for the better.

Place It and Set It Up Just How You Like
Your room, your rules. With a range of LFE, line- and speaker-level inputs, Phase selection, and three DSP-controlled EQ settings to help match your sub to any room placement, you're in control right out of the box. Set up KUBE 8b where it's most convenient to you, match it to any main speaker, or with any type of music system and start exploring new depths in your sound.

Optimal Integration: Designed, Engineered, and Assembled In-House
KEF is quite possibly the only high-end subwoofer manufacturer that designs, engineers, and assembles the driver, cabinet, and circuitry in-house.
