Immersion

Go deep or go home. KEF's design and engineering team worked together to develop iBX. This Intelligent Bass Extension algorithm creates a wider depth that unlocks the full potential of the specially designed bass unit. It provides unparalleled precision and ultimate synchronicity between the amplifier, driver, and closed enclosure.

Simple setup

Kube subwoofers offer unparalleled flexibility and integrate optimally into any imaginable music system: a range of LFE, line, and speaker-level inputs, phase selection, and DSP-controlled EQ settings help you get the best out of a Kube. Place the sub in a convenient location and start exploring new depths in sound reproduction.

Integration

KEF may be the only high-end speaker manufacturer that designs, engineers, and assembles the driver, enclosure, and circuits in-house. This level of integration means that we are dedicated to pure sound and that the Kube remains true to that ideal. The result is a driver, enclosure, and amplifier that are perfectly matched.
