Short answer: the Rythmik F12. Both are rated 4.1/5 for sound quality (#21 and #24 of 212 subwoofers), and the Rythmik F12 costs $1,439 against $1,599 for the Rythmik E15, so with nothing between them on sound quality, price settles it.
Why pick the Rythmik E15: A compact sealed 15” Direct Servo subwoofer, narrower and shallower than Rythmik’s F15, driven by the 600W H600 amplifier. The tradeoff: No independent measurements yet, so its output can’t be compared directly with ranked subwoofers; the rating is estimated from the measured sealed Rythmik F12 and ported Rythmik FV15HP (119.3 and 122.0dB in the 40 to 80Hz CEA-2010 bands).
The case for the Rythmik F12: Sealed 12-inch servo with 370W RMS offers excellent value.
Buy the Rythmik F12. Both are rated the same for sound quality, and it costs $160 less than the Rythmik E15.
About the ratings: the Rythmik E15’s rating is estimated from measured siblings and predecessors rather than its own measurements, with a likely range of 3.7 to 4.2, so this verdict could change once it is measured.
