Short answer: both are discontinued, so this only matters if you are buying used. Used, the PSB Speakers SubSeries 250 is the better pick: it ranks #104 of 212 subwoofers by sound quality (rated 3.7/5), against #189 (rated 3.2/5) for the Jamo C 912 SUB. If you want one new, the Monoprice SW-12 ranks #6 at $364.99.
What the Jamo C 912 SUB does well: A 12 inch ported subwoofer with a front port for flexible placement, for music and movies, now discontinued. The tradeoff: Maximum output in the upper bass trails the Infinity Speakers REFERENCE SUB R12, so it runs out of headroom sooner at high volume.
The PSB Speakers SubSeries 250 is the better-sounding choice. A compact sealed 10 inch subwoofer for smaller rooms and tight spaces, now discontinued. Watch for: Output at 31.5Hz is 102.2dB and 96.7dB at 25Hz, so it is not for large rooms or loud movie effects.
Buy the PSB Speakers SubSeries 250 only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, start with the Monoprice SW-12 instead.
