Short answer: the ELAC PS350. Both are rated 3.6/5 for sound quality (#121 and #147 of 212 subwoofers), and the ELAC PS350 costs $1,698 against $2,099 for the PSB SubSeries BP8, so with nothing between them on sound quality, price settles it.
Why pick the ELAC PS350: 12” woofer (24Hz) with 350W RMS, 700W peak.
Why pick the PSB SubSeries BP8: A sealed subwoofer with two opposed 8” woven carbon fiber drivers and a 500W continuous nCore-based amplifier, rated 25 to 150Hz (±3dB) and 20Hz at -10dB from a 33cm cabinet. Watch for: 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 and PSB Speakers SubSeries 450 (112.5 and 122.1dB in the 40 to 80Hz CEA-2010 bands).
Buy the ELAC PS350. Both are rated the same for sound quality, and it costs $401 less than the PSB SubSeries BP8.
Worth knowing: the PSB SubSeries BP8 has not been measured yet. Its rating is estimated from related models, with a likely range of 3.2 to 3.9, so treat this verdict as provisional.
