Short answer: the QSC K12.2. It ranks #1 of 83 12-inch pa speakers by sound quality, rated 4.7/5, at $899.99; the Coda Audio G712 ranks #31, rated 3.8/5, and costs $3,910, so there is not much of a tradeoff to weigh.
The QSC K12.2 is the more accurate, deeper-bass choice. A reliable 12 inch PA speaker with excellent sound and flexible built in processing, a safe choice for most events. Its measured preference score, a predictor of how neutral it sounds, is 5.46 against 3.14 for the Coda Audio G712. Its bass reaches about 48Hz before falling 3dB, against 85Hz for the Coda Audio G712. It keeps a wired aux input, which the Coda Audio G712 lacks. The tradeoff: The underlying Spinorama source is low quality, so its apparent measured lead deserves caution.
What the Coda Audio G712 does well: An extremely loud passive 12 inch PA speaker with a coaxial mid and high driver and a rotatable waveguide for portable or installed use. The catch: Bass measures 85Hz at -3dB and about 52Hz at -10dB, so a subwoofer is needed for full-range music.
Buy the QSC K12.2. It is rated higher for sound quality than the Coda Audio G712 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.

- Tonal accuracy above the bass: with a subwoofer taking the low end, the QSC K12.2 scores 7.7 against 6.0 for the Coda Audio G712 on the Spinorama preference scale. Its frequency response and off-axis sound are smoother, so voices and instruments sound closer to the recording.
