Compare the KEF Kube 10 MIE and Kube 12 MIE subwoofers side by side. Learn which size and power rating fits your room and listening habits best.
Quick answer
Choose the Kube 10 MIE if your room is smaller and you want tight, controlled bass. Choose the Kube 12 MIE if you have a larger space and crave deeper, more powerful low-end rumble.
What they share: the same amplifier and processing
Both the Kube 10 MIE and Kube 12 MIE use a 300 Watt Class D amplifier and KEF's Music Integrity Engine®. This means both models deliver clean, distortion-free bass with impressive dynamics for their size. The sealed cabinet design on both helps keep bass punchy and articulate, which is great for music as well as movies.
Where size changes the experience
The main difference is the driver size: 10 inches on the Kube 10 MIE versus 12 inches on the Kube 12 MIE. A larger driver moves more air, which translates to deeper bass extension and a more physical, room-filling presence. In a small to medium room, the Kube 10 MIE can already produce satisfying low end without overwhelming the space. In a larger room or a dedicated home theater, the Kube 12 MIE's extra output helps create that chest-thumping rumble you feel during action scenes.

- Bass depth and power: The Kube 12 MIE's 12-inch driver delivers deeper extension and higher output, making it the better choice for large rooms or home theater setups where you want to feel the bass.
- Bass accuracy and integration: The Kube 10 MIE's 10-inch driver and sealed cabinet produce tighter, more controlled bass that blends seamlessly with bookshelf speakers in smaller rooms.

Measure your available space before deciding; both models are available in multiple color options.
