Short answer: both are discontinued, so this only matters if you are buying used. Used, the JTR Speakers Captivator 1400 is the better pick: it ranks #30 of 143 subwoofers by sound quality (rated 4.3/5), against #130 (rated 3.7/5) for the HSU Research VTF-3 MK3. If you want one new, the HSU Research VTF-3 MK5 HP replaces the HSU Research VTF-3 MK3 and is rated 4.2/5 at $1,049.
The JTR Speakers Captivator 1400 is the better-sounding option. A low, wide 18 inch ported subwoofer with strong deep bass for movies, easy to tuck under a screen or riser. Watch for: The 508.0H x 762.0W x 571.5D mm cabinet and 142 lbs (64.4 kg) mass make this a serious placement and moving commitment.
What the HSU Research VTF-3 MK3 does well: A rear ported 12 inch subwoofer with useful deep bass output for its size, now discontinued. 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 JTR Speakers Captivator 1400 only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, buy the HSU Research VTF-3 MK5 HP, which replaces the HSU Research VTF-3 MK3.
