Short answer: both are discontinued, and they are rated the same for sound quality (#9 and #5 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.
Buy the JTR Speakers Captivator S2 or the Power Sound Audio (PSA) TRIAX, whichever you find used in better condition; both are discontinued. For a new speaker, start with the JTR Speakers Orbit Shifter PRO instead.
