Short answer: the KEF Kube 10 MIE is the newer model that replaces the Kef Kube 10B, but only the Kef Kube 10B has been measured and ranked so far, so this comparison is on specs and features rather than sound. The Kef Kube 10B is discontinued, so it is now a used buy.

Price: the KEF Kube 10 MIE lists at $899.99 and the Kef Kube 10B at $800.

The Two Speakers In Full
KEF Kube 10 MIE: $899.99 KEF eBay
Older model: the Kef Kube 10B (rated 3.7/5).
Pros: Sealed cabinet with a 10-inch driver and 300W of amplification, tuned by KEF’s Music Integrity Engine DSP. The sealed design is easier to place than a ported one and suits music.
Cons: No independent measurements yet, so its output can’t be compared with ranked subwoofers. A single 10-inch sealed driver limits deep output in a large room.
