Short answer: the Rythmik F12 for better sound quality, the BIC America PL-300 for the lower price. The Rythmik F12 ranks #21 of 212 subwoofers, rated 4.1/5, at $1,439. The BIC America PL-300 ranks #89, rated 3.7/5, at $449, $990 cheaper.
The Rythmik F12 is the better-sounding choice. A sealed servo subwoofer with deep, musical bass and excellent build quality, a strong value for music lovers. The catch: The sealed 12-inch driver cannot reproduce the deepest cinema effects, so a pair is advised for theater.
The case for the BIC America PL-300: An affordable ported 12 inch subwoofer with three ports, adjustable tuning and a strong amplifier. Watch for: At 48.1 lbs (21.8 kg) and 457 x 387 x 476mm it is a large, heavy cabinet that needs floor space.
Buy the Rythmik F12 when sound quality outweighs the price for you, and the BIC America PL-300 when the price outweighs sound quality instead.
