Short answer: the SVS SB-1000 PRO. It ranks #4 of 73 subwoofers by sound quality, rated 3.7/5, at $599; the KEF Kube 8 MIE ranks #21, rated 3.6/5, and costs $699.99, so there is not much of a tradeoff to weigh.
Why pick 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. Watch for: 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.
Why pick the KEF Kube 8 MIE: Compact sealed enclosure with an 8-inch front-firing long-throw driver powered by a 300W Class-D amplifier. The tradeoff: 8-inch sealed driver rolls off below 34Hz (-6dB) and tops out at 105dB max SPL, which limits visceral home-theater infrasonic punch in medium to large rooms compared with larger subwoofers.
Buy the SVS SB-1000 PRO. It is rated higher for sound quality than the KEF Kube 8 MIE and costs less, which makes it the one to get unless you need something the other one does better.
Worth knowing: the KEF Kube 8 MIE has not been measured yet. Its rating is estimated from related models, with a likely range of 3.4 to 3.8, so treat this verdict as provisional.

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.
