Short answer: the QSC K12.2. It ranks #1 of 50 12-inch pa speakers by sound quality (rated 4.7/5); the Coda Audio G512 ranks #32 (rated 3.6/5).
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.
Why pick the Coda Audio G512: High-quality vendor Spinorama data gives preference scores of 3.04 standalone and 6.11 with an ideal subwoofer. The tradeoff: Measured bass reaches only about 112Hz (-3dB), and listening-window narrow-band deviation is 0.531, so the tonal balance is thin and uneven compared with the leaders in this ranking.

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.

Coda Audio G512 Passive eBay
Pros: High-quality vendor Spinorama data gives preference scores of 3.04 standalone and 6.11 with an ideal subwoofer. A 98dB sensitivity and 132dB peak rating come from a 16kg cabinet, and the rotatable 90° x 60° waveguide fits horizontal or vertical placement. Measured bass extension of 112Hz (-3dB).
Cons: Measured bass reaches only about 112Hz (-3dB), and listening-window narrow-band deviation is 0.531, so the tonal balance is thin and uneven compared with the leaders in this ranking. It is passive, so an amplifier and processor with the maker’s presets are required.
