Short answer: the PSB SubSeries BP8. It ranks #147 of 212 subwoofers by sound quality, rated 3.6/5, at $2,099. The Neumann KH 750 DSP ranks #150, rated 3.5/5, at $1,999, $100 cheaper, a saving that is not big enough to make up the sound-quality gap.
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).
The case for the Neumann KH 750 DSP: Sealed 10-inch studio subwoofer engineered for precision monitoring and seamless integration with Neumann KH 80, KH 120, and Neumann KH 150 monitors. The catch: Sealed compact cabinet and 256W amplifier are tuned for studio accuracy down to 18Hz rather than massive peak sound-pressure levels in home-theater spaces.
Buy the PSB SubSeries BP8. It is rated higher for sound quality, and the $100 saving on the Neumann KH 750 DSP is not enough to make up the difference.
About the ratings: the PSB SubSeries BP8’s rating is estimated from measured siblings and predecessors rather than its own measurements, with a likely range of 3.2 to 3.9, so this verdict could change once it is measured.
