Short answer: the ELAC PS350. It ranks #121 of 212 subwoofers by sound quality, rated 3.6/5, at $1,698; the Neumann KH 750 DSP ranks #150, rated 3.5/5, and costs $1,999, so there is not much of a tradeoff to weigh.
Why pick the ELAC PS350: 12” woofer (24Hz) with 350W RMS, 700W peak.
Why pick 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. Watch for: 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 ELAC PS350. It is rated higher for sound quality than the Neumann KH 750 DSP and costs less, which makes it the one to get unless you need something the other one does better.
