Short answer: the Klipsch Reference Premiere RP-1400SW. It ranks #108 of 143 subwoofers by sound quality, rated 4.0/5, at $1,249.99; the HSU Research VTF-TN1 ranks #115, rated 3.9/5, at $1,249. The price gap is small enough that the sound-quality ranking should decide it.
The case for the Klipsch Reference Premiere RP-1400SW: Features a 14-inch spun-copper front-firing Cerametallic woofer powered by a 500-watt RMS / 1000-watt peak Class D amplifier. The catch: Substantial 83.8 lbs (38.0 kg) weight and deep 652 mm cabinet require dedicated floor space.
The case for the HSU Research VTF-TN1: Independent CEA-2010 testing (2 ports open) records 107.8 dB at 20 Hz and 117.6 dB through 40-80 Hz. The catch: The tall 29.5” cabinet has an unusual footprint compared to squatter subs in this class.
Buy the Klipsch Reference Premiere RP-1400SW. It is rated higher for sound quality, and the $0.99 saving on the HSU Research VTF-TN1 is not enough to make up the difference.
About the ratings: the Klipsch Reference Premiere RP-1400SW’s rating is estimated from measured siblings and predecessors rather than its own measurements, with a likely range of 3.8 to 4.2, so this verdict could change once it is measured.
