Short answer: the d&b audiotechnik 10S. It ranks #18 of 42 10-inch pa speakers by sound quality, rated 3.7/5, at $1,399; the Seeburg K20 ranks #22, rated 3.6/5, and costs $1,969, so there is not much of a tradeoff to weigh.
The d&b audiotechnik 10S is the deeper-bass choice. A compact passive 10 inch speaker with a rotatable horn, designed for theaters, churches and fill duty in permanent installs. Its bass reaches about 75Hz before falling 3dB, against 95Hz for the Seeburg K20. Watch for: Listening-window deviation of 0.608 means tonal balance is less even than the flattest 10-inch models.
What the Seeburg K20 does well: A loud passive PA speaker with two 10 inch woofers and a large compression driver, suited to installs paired with a subwoofer. The tradeoff: Bass reaches only about 95Hz (-3dB) and on-axis narrow-band deviation is 0.562, so the response is uneven and thin without a subwoofer.
Buy the d&b audiotechnik 10S. It is rated higher for sound quality than the Seeburg K20 and costs less, so only choose the other one for a particular feature it does better.
