Power Sound Audio (PSA) S3600i vs JTR Speakers Captivator 1400

Short answer: both are discontinued, and they are rated the same for sound quality (#31 and #30 of 143 subwoofers). Either one is only an option used, so choose on condition and price. If you want one new, the JTR Speakers Orbit Shifter PRO ranks #1 at $4,499.

What the Power Sound Audio (PSA) S3600i does well: A sealed dual 18 inch subwoofer with formidable upper bass punch for movie effects and music in a large room. Watch for: 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.

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. 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.

Buy the Power Sound Audio (PSA) S3600i or the JTR Speakers Captivator 1400, whichever you find used in better condition; both are discontinued. For a new speaker, start with the JTR Speakers Orbit Shifter PRO instead.
