Short answer: the Monoprice SW-15. It ranks #14 of 212 subwoofers by sound quality (rated 4.1/5) at $499.99 and is still sold new; the HSU Research VTF-1 MK3 ranks #63 (rated 3.8/5) and is discontinued, so it is only an option used.
The case for 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.
Why pick the HSU Research VTF-1 MK3: An affordable ported 10 inch subwoofer with switchable tuning modes and deep bass for smaller rooms, now discontinued. The tradeoff: The cabinet is 42.1 lbs (19.1 kg) and about 50cm tall and 48cm deep, large for a 10 inch subwoofer.
Buy the Monoprice SW-15. It is rated higher for sound quality, and the HSU Research VTF-1 MK3 is discontinued, so it is only available used.
