8 inches bass driver active subwoofer

Don't let its compact size fool you, the Kube 8b may not take up much space but the bass it delivers is anything but small. With an 8 inches driver the Kube8b is perfect for smaller living rooms. It shares the 300 Watts Class D amp from the bigger Kubes and has iBX technology to extend the bass depth dynamically.

Hear new dimensions in sound with Kube subwoofers

The Kube 8b effortlessly unleashes explosive power. iBX technology extends the bass depth dynamically 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.

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.

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 place, match it to any main speaker or type of music system and start exploring new depths in the sound.

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 committed to pure sound and the Kube stays true to that ideal. The result is a driver and amplifier that are perfectly in tune.
