Key Features
The Kube 12b is the largest of the Kube Subwoofers from KEF. It has been engineered to deliver the deepest bass for both music and movies, so it works in both a hi-fi and home cinema setup. If you want to feel the earth move from the power of bass, look no further.
Kube 12b has a 300-watt Class D amplifier making it ideal for larger rooms. A large 12-inch driver and iBX technology dynamically extend bass depth. This sub makes a great accompaniment to systems with larger floorstanding or bookshelf speaker models for consistent levels of power and dispersion.

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.
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.
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.
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.
