Short answer: the QSC K12.2. It ranks #1 of 50 12-inch pa speakers by sound quality (rated 4.7/5); the DB Audiotechnik 24S ranks #28 (rated 3.8/5).
What the QSC K12.2 does well: The strongest all-round tonal result in this popular-model group: the vendor Spinorama data produces a 7.73 ideal-subwoofer preference score and 48Hz measured bass extension. The tradeoff: The underlying Spinorama source is low quality, so its apparent measured lead deserves caution.
The case for the DB Audiotechnik 24S: Manufacturer measurements give preference scores of 3.11 standalone and 5.81 with an ideal subwoofer, and two 12-inch woofers reach 69Hz at -3dB and about 53Hz at -10dB. Watch for: The 3.4dB reference band means tonal balance is less even than the best 12-inch speakers here.

QSC K12.2: $899.99 Amazon B&H Photo Video Guitar Center eBay
Pros: The strongest all-round tonal result in this popular-model group: the vendor Spinorama data produces a 7.73 ideal-subwoofer preference score and 48Hz measured bass extension. Extensive onboard DSP, flexible main/monitor use and a long market track record make it an unusually safe general-purpose choice. Measured bass extension of 48Hz (-3dB).
Cons: The underlying Spinorama source is low quality, so its apparent measured lead deserves caution. It is not the cheapest 12-inch option, and serious dance music or high-output live use still benefits from a subwoofer.

DB Audiotechnik 24S Passive eBay
Pros: Manufacturer measurements give preference scores of 3.11 standalone and 5.81 with an ideal subwoofer, and two 12-inch woofers reach 69Hz at -3dB and about 53Hz at -10dB. A 1.4-inch compression driver on a rotatable 75° x 45° horn and a 138dB peak rating give long throw for larger rooms. It can run full range on its own or pair with d&b xS subwoofers. Measured bass extension of 69Hz (-3dB).
Cons: The 3.4dB reference band means tonal balance is less even than the best 12-inch speakers here. It is a large 33kg passive cabinet meant for permanent installs, needing d&b amplifiers and presets. It is sold only through d&b dealers with no published price.
