Short answer: the Rythmik FV15HP, if you are buying new. The JTR Speakers Captivator 1400 ranks higher than it (#30 vs #55 of 143 subwoofers, 4.3/5 vs 4.2/5) but is discontinued, so only consider it used; the Rythmik FV15HP is still sold new at $2,127.
What the JTR Speakers Captivator 1400 does well: A low, wide 18 inch ported subwoofer with strong deep bass for movies, easy to tuck under a screen or riser. The tradeoff: 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.
Why pick the Rythmik FV15HP: A 15 inch ported subwoofer with output matching pricier rivals, plus balanced and RCA inputs for flexible setups. The catch: Premium price ($2127), ported design room gain dependency, and mid-to-large 114.6 lbs (52 kg) footprint.
Buy the Rythmik FV15HP new; the JTR Speakers Captivator 1400 is no longer sold new, so it only makes sense as a used find.
