Short answer: the SVS SB-1000 PRO. Both are rated 3.7/5 for sound quality (#4 and #109 of 73 subwoofers), and the SVS SB-1000 PRO costs $599 against $1,099.99 for the KEF Kube 12 MIE, so with nothing between them on sound quality, price settles it.
Why pick the KEF Kube 12 MIE: Sealed 12-inch front-firing driver with 300W Class-D power managed by KEF Music Integrity Engine DSP. The catch: While deep and controlled for music, its 300W amplifier provides lower headroom for extreme reference movie volume compared to high-power competitor subwoofers with 800W+ amplifiers in the same price range.
The case for the SVS SB-1000 PRO: 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 tradeoff: 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 $500.99 less than the KEF Kube 12 MIE.
Worth knowing: the KEF Kube 12 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.

SVS SB-1000 PRO: $599.00 Amazon eBay
Older models: the SVS SB-1000 (ranked higher, rated 3.9/5) and the SVS SB12-NSD (rated 3.4/5). See every SVS subwoofers generation.
Same family: the SVS PB-1000 PRO (smaller subwoofer, rated 3.8/5), the SVS PB-2000 PRO (smaller subwoofer, rated 3.9/5), the SVS SB-2000 Pro (larger subwoofer, rated 3.8/5) and the SVS PC-2000 Pro (larger subwoofer, estimated 3.7/5).
Pros: 12-inch sealed driver delivers 113.9dB CEA-2010-A average, the highest output of any subwoofer in the under-30lb weight class. Sealed enclosure keeps bass tight and controlled for its compact footprint.
Cons: 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. Its strength is the 50 to 80Hz range, so it suits music and smaller rooms better than movie effects that dig below 30Hz.
