Short answer: the Klipsch SPL-120. Both are rated 4.1/5 for sound quality (#19 and #21 of 212 subwoofers), and the Klipsch SPL-120 costs $429.99 against $1,439 for the Rythmik F12, so with nothing between them on sound quality, price settles it.
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 catch: The sealed 12-inch driver cannot reproduce the deepest cinema effects, so a pair is advised for theater.
The case for the Klipsch SPL-120: An affordable 12 inch ported subwoofer with room filling, clean bass and optional wireless connection. The tradeoff: Port chuffing is the known flaw: testers could not run it past about 60 to 70% volume before the noise became bothersome, a problem Klipsch fixed in the newer Klipsch RP-1200SW.
Buy the Klipsch SPL-120. Both are rated the same for sound quality, and it costs $1,009.01 less than the Rythmik F12.
