Short answer: the Monoprice SW-15. It ranks #14 of 212 subwoofers by sound quality, rated 4.1/5, at $499.99; the HSU Research VTF-2 MK5 ranks #40, rated 3.9/5, and costs $759, which makes this an easy call rather than a real tradeoff.
Why pick the Monoprice SW-15: A big 15 inch subwoofer with powerful, punchy bass at a budget price, great for movies in a large room. The tradeoff: Budget-tier design, ported room gain dependency, 66.1 lbs (30 kg) mid-size, and limited dynamic headroom.
The case for the HSU Research VTF-2 MK5: A loud ported 12 inch subwoofer with adjustable tuning, tuneful bass and great value for music and movies. The tradeoff: There is no remote, app, DSP or room correction, so everything is dialed in by hand.
Buy the Monoprice SW-15. It is rated higher for sound quality than the HSU Research VTF-2 MK5 and costs less, so only choose the other one for a particular feature it does better.
