From the manufacturer

KEF KUBE Subwoofers offer deep punchy bass.

Hear new dimensions in sound with Kube subwoofers

The Kube 12b effortlessly unleashes explosive power. iBX technology dynamically extends bass depth and KEF’s unique ability to design, build and integrate the driver in-house takes optimisation to a whole new level. Delivering immersive music and home theatre sound that takes you to the heart of the performance.

Exceptional Integration with all speakers.

DSP Control to fit in any room.

Deep bass for music and movies.

Complete integration with home stereo.

Power and Technology

Perfect for creating a deep and clean rumble in large rooms. The Kube line has a 300 Watts Class D amplifier powering bespoke drivers as well as iBX technology to dynamically extend bass depth.

Easy configuration

Kube subwoofers offer unmatched set up flexibility. A range of LFE, line and speaker-level inputs, phase selection and DSP controlled EQ settings help you get the best from a Kube. Put it in a convenient position, match it to any main speaker or type of music system, and start exploring new depths in the sound.

Immersiveness

Go deep or go home. KEF’s design and engineering team worked in chorus to develop iBX. This Intelligent Bass Extension algorithm creates an extended depth that unlocks the full potential of the custom driver. Giving you unparalleled precision and ultimate synchronicity between amplifier, driver and sealed cabinet.

Deep Bass

The Kube line is engineered to deliver the deepest bass for music and movies, if you want to feel the earth move look no further.

Three sizes to choose from, KUBE8b, KUBE10b, KUBE12b

Integration

KEF is quite possibly the only high-end manufacturer that designs, engineers and assembles the driver, cabinet and circuitry in-house. This level of integration means we are commited to pure sound and the Kube stays true to that ideal. The result is a driver and amplifier that are perfectly in tune.
