Short answer: the KEF Kube 10 MIE, if you are buying new. The KEF Kube 10B measures as well as it (#100 vs #11 of 73 subwoofers, 3.7/5 vs 3.7/5) but is discontinued, so only consider it used; the KEF Kube 10 MIE is still sold new at $699.99.
The case for the KEF Kube 10 MIE: A sealed 10 inch subwoofer with a 300 watt amp and bass processing, easy to place and suited to music. Watch for: No independent measurements yet, so its output can’t be compared with ranked subwoofers.
The case for the KEF Kube 10B: A sealed 10 inch subwoofer for small to medium rooms, with EQ presets and smart limiting, now discontinued. The catch: Output falls to about 92dB at 16Hz, so the deepest movie effects are limited.
Buy the KEF Kube 10 MIE if you want one new; the KEF Kube 10B is discontinued, so only look for it used.
About the ratings: the KEF Kube 10 MIE’s rating is estimated from measured siblings and predecessors rather than its own measurements, with a likely range of 3.5 to 3.9, so this verdict could change once it is measured.
