KEF KUBE 12 MIE 12" Subwoofer

The KEF Kube 12 MIE is a high-performance subwoofer that brings impressive low-frequency impact and refinement to both music and home theatre systems. Powered by a 12-inch driver and a 300-watt Class D amplifier, the Kube 12 MIE delivers rich, authoritative bass that enhances the depth and realism of your favourite recordings and movie soundtracks.

Central to the Kube 12 MIE’s performance is KEF’s Music Integrity Engine® (MIE), an advanced digital signal processing suite that optimises the interaction between the amplifier and driver. The result is bass that feels clean, controlled, and naturally integrated with your main speakers — with strong low-end extension and minimal distortion.

The sealed enclosure design helps maintain tight, articulate bass that supports punchy rhythms and deep cinematic effects without overwhelming the overall system balance. Whether paired with compact bookshelf speakers or full-range floorstanders, the Kube 12 MIE seamlessly fills the room with impactful low frequencies, improving the sense of scale and presence in your listening experience.

Adjustable controls, including crossover and phase, along with multiple room EQ settings, let you tune the subwoofer to your room’s acoustics and placement. For added convenience, this model can also be paired wirelessly with compatible KEF systems using an optional wireless adapter, offering a cleaner setup with fewer cables.
