Short answer: the Rythmik L12. It ranks #25 of 212 subwoofers by sound quality, rated 4.0/5, at $791. The HSU Research VTF-2 MK5 ranks #40, rated 3.9/5, at $759, $32 cheaper, which does not close the gap in sound quality.
What the Rythmik L12 does well: Rythmik’s least expensive subwoofer: a sealed 12” with Rythmik’s Direct Servo feedback, which lowers distortion and compression, and a 300W Hypex amplifier with one band of parametric EQ. 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 (119.3dB in the 40 to 80Hz CEA-2010 bands) and placed below it, since the L12 has a less powerful amplifier.
The case for the HSU Research VTF-2 MK5: Plays 50% louder across measurement range than competitors.
Buy the Rythmik L12. It is rated higher for sound quality, and the $32 you would save on the HSU Research VTF-2 MK5 does not close the gap.
Worth knowing: the Rythmik L12 has not been measured yet. Its rating is estimated from related models, with a likely range of 3.7 to 4.1, so treat this verdict as provisional.
