Short answer: the Bowers & Wilkins ASW610. Both are rated 3.3/5 for sound quality (#41 and #43 of 73 subwoofers), and the Bowers & Wilkins ASW610 costs $1,000 against $1,249 for the PSB SubSeries BP7, so with nothing between them on sound quality, price settles it.
The case for the Bowers & Wilkins ASW610: 10-inch long-throw paper/aramid fiber driver in a sealed cabinet powered by a 200W Class D amplifier. The catch: 200W amplifier limits dynamic headroom during heavy low-frequency effects.
The case for the PSB SubSeries BP7: A compact sealed subwoofer with two 6.5” woven carbon fiber drivers mounted in opposition, which cancels cabinet vibration, driven by a 350W Class D amplifier. The catch: No independent measurements yet, so its output can’t be compared directly with ranked subwoofers; the rating is estimated from the measured PSB Speakers SubSeries 250 (112.5dB in the 40 to 80Hz CEA-2010 bands).
Buy the Bowers & Wilkins ASW610. Both are rated the same for sound quality, and it costs $249 less than the PSB SubSeries BP7.
About the ratings: neither speaker has been measured yet, so both ratings are estimated from measured siblings and predecessors (likely ranges: Bowers & Wilkins ASW610 3.1 to 3.5; PSB SubSeries BP7 2.9 to 3.6). Treat this verdict as provisional.

PSB SubSeries BP7: $1,249.00 Estimated Amazon eBay
Same family: the PSB SubSeries BP8 (larger subwoofer, estimated 3.6/5) and the PSB SubSeries BP12 (larger subwoofer, estimated 4.2/5).
Pros: A compact sealed subwoofer with two 6.5” woven carbon fiber drivers mounted in opposition, which cancels cabinet vibration, driven by a 350W Class D amplifier. PSB rates it 28 to 150Hz (±3dB) and 25Hz at -10dB from a 27cm cube.
Cons: No independent measurements yet, so its output can’t be compared directly with ranked subwoofers; the rating is estimated from the measured PSB Speakers SubSeries 250 (112.5dB in the 40 to 80Hz CEA-2010 bands). Two 6.5” drivers have limited cone area, so output is modest.
