Short answer: both are discontinued, so this only matters if you are buying used. Used, the Emotiva X-Ref 12 is the better pick: it ranks #164 of 212 subwoofers by sound quality (rated 3.4/5), against #205 (rated 3.0/5) for the Emotiva X-Ref 10. If you want one new, the JTR Speakers Captivator 212PRO ranks #1 at $2,799.
Why pick the Emotiva X-Ref 10: A compact sealed 10” subwoofer with 300W. Watch for: No independent measurements yet, so its output can’t be compared with ranked subwoofers.
The Emotiva X-Ref 12 is the better-sounding pick. 600W sealed 12-inch with smooth linear response and 2-band parametric EQ.
Buy the Emotiva X-Ref 12 only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, start with the JTR Speakers Captivator 212PRO instead.
About the ratings: the Emotiva X-Ref 10’s rating is estimated from measured siblings and predecessors rather than its own measurements, with a likely range of 2.7 to 3.3, so this verdict could change once it is measured.
