Short answer: the Kali Audio WS-6.2. It ranks #198 of 212 subwoofers by sound quality, rated 3.0/5, at $599; the Aperion Audio Bravus II 10D ranks #209, rated 2.9/5, and costs $899, so there is little reason to consider the other one.
The case for the Kali Audio WS-6.2: Dual 6.5-inch ported drivers deliver 104.5dB CEA-2010-A average in a compact powered design.
What the Aperion Audio Bravus II 10D does well: Compact 15 inch tall cabinet pairs a down-firing 10 inch aluminum cone woofer with two side-firing 10 inch passive radiators. Watch for: No independent measurements yet, so its output can’t be compared with ranked subwoofers; the rating is estimated from the measured original Aperion Audio Bravus 10D, which averaged only 102.5dB in the 40 to 80Hz CEA-2010 bands and 79dB at 20Hz.
Buy the Kali Audio WS-6.2. It is rated higher for sound quality than the Aperion Audio Bravus II 10D and costs less, so only choose the other one for a particular feature it does better.
About the ratings: the Aperion Audio Bravus II 10D’s rating is estimated from measured siblings and predecessors rather than its own measurements, with a likely range of 2.6 to 3.2, so this verdict could change once it is measured.

Aperion Audio Bravus II 10D: $899.00 Estimated Amazon Aperion Audio eBay
Older model: the Aperion Audio Bravus 10D (ranked higher, rated 2.9/5). See every Aperion Audio Bravus generation.
Same family: the Aperion Audio Bravus II 8D (smaller subwoofer, estimated 2.6/5) and the Aperion Audio Bravus II 12D (larger subwoofer, ranked higher, rated 3.7/5).
Pros: Compact 15 inch tall cabinet pairs a down-firing 10 inch aluminum cone woofer with two side-firing 10 inch passive radiators. A 500W RMS Class D amplifier (1,000W peak) drives it, and Aperion rates it at 28Hz at the -3dB point. Aperion sells it direct with a 30 day in-home trial and free shipping in the continental US.
Cons: No independent measurements yet, so its output can’t be compared with ranked subwoofers; the rating is estimated from the measured original Aperion Audio Bravus 10D, which averaged only 102.5dB in the 40 to 80Hz CEA-2010 bands and 79dB at 20Hz. Its 2 year amplifier warranty is short next to the 5 years on cabinet and drivers.
