Short answer: the HSU Research VTF-3 MK5 HP. It ranks #59 of 143 subwoofers by sound quality, rated 4.2/5, at $1,049; the REL Acoustics HT/1510 Predator II ranks #98, rated 4.1/5, and costs $1,799, so there is little reason to consider the other one.
Why pick the HSU Research VTF-3 MK5 HP: A 15 inch ported subwoofer with excellent output for the money, a strong value pick for movies and music. The catch: Ported design requires careful room placement, mid-size 86 lbs (39 kg) cabinet, and mid-range output.
The case for the REL Acoustics HT/1510 Predator II: A sealed 15 inch home theater subwoofer with strong, punchy upper bass for movie effects and music. The tradeoff: Deep-bass output is more limited than the strong 40-80 Hz result suggests, so it is not the right choice when the lowest movie effects are the priority.
Buy the HSU Research VTF-3 MK5 HP. It is rated higher for sound quality than the REL Acoustics HT/1510 Predator II and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
