KEF KUBE 8 MIE 8" Subwoofer

The KEF Kube 8 MIE is a compact yet capable subwoofer designed to bring punchy, controlled low frequencies to smaller systems and rooms without taking up much space. Featuring an 8-inch driver powered by a 200-watt Class D amplifier, the Kube 8 MIE delivers rich, impactful bass that enhances both music and movie soundtracks with depth and presence.

At the core of the Kube 8 MIE is KEF’s Music Integrity Engine® (MIE), advanced digital signal processing that optimises how the amplifier and driver interact. The result is bass that feels tight and accurate, integrating naturally with your main speakers so that low frequencies support the performance without overpowering it.

The sealed cabinet design contributes to clean, musical low-end response that works especially well in smaller to medium living spaces. Whether you’re enjoying films with deeper effects or music that calls for weight and rhythm, the Kube 8 MIE provides a solid, well-controlled foundation.

Built-in controls — including crossover, phase, and multiple room EQ settings — make it easy to adapt the subwoofer to your room and speaker placement. For added flexibility and a cleaner setup, the Kube 8 MIE can also be paired wirelessly with compatible KEF systems using an optional wireless adapter, eliminating the need for long subwoofer cables.
