Short answer: the Roku Subwoofer 9201X on measured sound quality, the PSB Speakers SubSeries 100 on price. The Roku Subwoofer 9201X ranks #40 of 42 subwoofers at $399. The PSB Speakers SubSeries 100 ranks #41 at $299, $100 cheaper.
What the PSB Speakers SubSeries 100 offers: Independent CEA-2010 testing records 72.1 dB at 20 Hz and 93.2 dB (avg of 3/4 bands) through 40-80 Hz. The sealed enclosure with 5.25” (133mm) driver is best suited to upper-bass support in a modest room. Watch for: Deep-bass output is limited relative to its midbass result, so it is not the right choice for the lowest movie effects. The 161.8H x 161.8W x 199.9D mm cabinet and 2.7 kg mass still need deliberate placement and calibration.
What the Roku Subwoofer 9201X offers: A simple 7.8kg wireless add-on for compatible Roku TV and Roku audio systems, with easy setup and useful bass reinforcement for dialogue-focused television and casual movies. Its sealed 10-inch cabinet is compact enough to tuck beside furniture, and reviews find that it adds satisfying low-end weight to the Roku ecosystem without extra cables. Watch for: It is locked to compatible Roku products and cannot serve as a conventional subwoofer. Measured output is modest, particularly below 40Hz: 77.9dB at 20Hz, 79.3dB at 25Hz and 85.1dB at 31.5Hz. This discontinued model is for convenient modest bass, not high-impact home theater or large rooms.
Buy the PSB Speakers SubSeries 100 when the price outweighs sound quality for you, and the Roku Subwoofer 9201X when sound quality outweighs the price instead.
Neither of these is a sound-quality pick. Look higher up the 42 subwoofers if that is what you are optimizing for.
