Short answer: the Rythmik F12. It ranks #21 of 212 subwoofers by sound quality (rated 4.1/5) at $1,439 and is still sold new; the JBL HDI-1200P ranks #32 (rated 3.9/5) and is discontinued, so it is only an option used.
The case for the Rythmik F12: A sealed servo subwoofer with deep, musical bass and excellent build quality, a strong value for music lovers. The tradeoff: The sealed 12-inch driver cannot reproduce the deepest cinema effects, so a pair is advised for theater.
Why pick the JBL HDI-1200P: A compact 12 inch subwoofer with a powerful amp, low distortion and adjustable crossover and phase for easy blending, now discontinued. The tradeoff: Output drops quickly below the port tuning, to 93.2dB at 25Hz against 109.5dB at 31.5Hz, so the deepest effects are limited.
Buy the Rythmik F12. It is rated higher for sound quality, and the JBL HDI-1200P is discontinued, so it is only available used.
