Hear new dimensions in sound with Kube subwoofers
The Kube 12b effortlessly unleashes explosive power. PBX technology dynamically extends the bass depth, and KEF’s unique ability to design, build, and integrate the driver in-house takes optimization to a whole new level. Deliver 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 BX. 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 setup 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.
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.
