Short answer: both are discontinued, and they are rated the same for sound quality (#11 and #12 of 212 subwoofers). Either one is only an option used, so choose on condition and price. If you want one new, the HSU Research ULS-15 MK2 ranks #4 at $999.
Buy the Paradigm Defiance X12 or the Power Sound Audio (PSA) XV15-BASE, whichever you find used in better condition; both are discontinued. For a new speaker, start with the HSU Research ULS-15 MK2 instead.
