Short answer: the SVS SB-1000 PRO. Both are rated 3.7/5 for sound quality (#4 and #11 of 73 subwoofers), and the SVS SB-1000 PRO costs $599 against $899 for the KEF Kube 10 MIE, so with nothing between them on sound quality, price settles it.
The case for the KEF Kube 10 MIE: Sealed cabinet with a 10-inch driver and 300W of amplification, tuned by KEF’s Music Integrity Engine DSP. Watch for: No independent measurements yet, so its output can’t be compared with ranked subwoofers.
What the SVS SB-1000 PRO does well: 12-inch sealed driver delivers 113.9dB CEA-2010-A average, the highest output of any subwoofer in the under-30 lbs (13.6 kg) weight class. The catch: As a sealed box it gives up output in the deepest octave: 91dB at 20Hz and 97.7dB at 25Hz, where a ported subwoofer like the RSL (Rogersound Labs) Speedwoofer 10S MKII reaches 100dB and 105dB.
Buy the SVS SB-1000 PRO. Both are rated the same for sound quality, and it costs $300 less than the KEF Kube 10 MIE.
Worth knowing: the KEF Kube 10 MIE has not been measured yet. Its rating is estimated from related models, with a likely range of 3.5 to 3.9, so treat this verdict as provisional.
