Seamless elegance

The sealed cabinet design facilitates optimal placement, while the contemporary design seamlessly blends with the room's decor.

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.

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.
