8-inch front-firing active subwoofer

The compact Kube 8 MIE may not take up much space, but the bass it delivers is far from small. With an 8-inch driver, it is ideally suited for smaller rooms. By sharing the same 300 Watts Class D amplifier from it's larger siblings, Kube 8 MIE exhibits unprecedented levels of control. With Music Integrity Engine®, the Kube 8 MIE is optimised to dynamically extend the bass depth.

Music Integrity Engine® (MIE)

KEF‘s proprietary DSP (Digital Signal Processing) algorithms ensure that every component of the subwoofer works in perfect harmony. Features such as iBX Intelligent Bass Extension provides even deeper and precise bass at any listening level.

Feel the force

The Kube features a front-firing long throw driver with a large cone area and high excursion, delivering higher output at lower frequencies. Its efficient and cool-running 300W Class D RMS amplifier further enhances performance.

Versatile immersion

The largest model in the Kube range with the highest output, perfect for movies, music, TV and gaming in larger rooms and dedicated home theatres.

Effortless wireless integration

The KW1 enables optimal placement of the Kube without being limited by cables. High-quality wireless transmission ensures the delivery of every nuance and impact from your favourite movies and music.

Well connected

Kube offers versatile connection options, including KEF SmartConnect and speaker level inputs, making connecting into any system a breeze.

3 room position EQ options

The intuitive preset options ensure excellent performance from Kube no matter where in the room it is placed.

Multiple power modes

'Auto wake up' detects audio signals for instant readiness, 'Always on' mode keeps it ready to play instantly, and '12V trigger' provides automatic wake-up.
