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 d&b audiotechnik 12S ranks #33, rated 3.8/5, and costs $1,350, which makes this an easy call rather than a real tradeoff.
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 3.20 for the d&b audiotechnik 12S. Its bass reaches about 48Hz before falling 3dB, against 60Hz for the d&b audiotechnik 12S. It keeps a wired aux input, which the d&b audiotechnik 12S lacks. Watch for: The underlying Spinorama source is low quality, so its apparent measured lead deserves caution.
Why pick the d&b audiotechnik 12S: A compact passive 12 inch installation speaker with bass deep enough for speech and background music without a subwoofer. The tradeoff: Listening-window deviation of 0.556 means the tonal balance is less even than the best 12-inch models.
Buy the QSC K12.2. It is rated higher for sound quality than the d&b audiotechnik 12S 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 5.8 for the d&b audiotechnik 12S on the Spinorama preference scale. Its frequency response and off-axis sound are smoother, so voices and instruments sound closer to the recording.
