Short answer: both are discontinued, and they are rated the same for sound quality (#32 and #31 of 212 subwoofers). Either one is only an option used, so choose on condition and price. If you want one new, the JTR Speakers Captivator 212PRO ranks #1 at $2,799.
Buy the JBL HDI-1200P or the Starke Sound SW15, whichever you find used in better condition; both are discontinued. For a new speaker, start with the JTR Speakers Captivator 212PRO instead.
