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.
