Kube 8 MIE: 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.

KW1 Wireless Subwoofer Adapter Kit: 

Comprising a discreet transmitter and receiver, KEF KW1 works with the Kube, KC62 and KC92 subwoofers. It allows KEF subs to be optimally placed, and not limited by cables. High-quality wireless transmission delivers every ounce of detail and impact from your favourite films and music.

The receiver is also available separately, allowing two KEF subwoofers to receive the same signal wirelessly from the same transmitter. 

KW1 operates in the high-bandwidth 5GHz band and delivers audio up to 24bit/48kHz. The transmitter is powered by USB, while the receiver is powered directly by the subs expansion port. Pairing is intuitive and highly stable, while a range of up to 30m (line of sight) makes placement easy. KW1 is also perfectly suited for use with KEF's LSX II LT, LSX II, LS50 Wireless II and LS60 Wireless.
