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 G712 ranks #27 (rated 3.8/5).
The case for the QSC K12.2: 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 catch: The underlying Spinorama source is low quality, so its apparent measured lead deserves caution.
What the Coda Audio G712 does well: High-quality manufacturer measurements give preference scores of 3.14 standalone and 6.01 with an ideal subwoofer. The catch: Bass measures 85Hz at -3dB and about 52Hz at -10dB, so a subwoofer is needed for full-range music.

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 G712 Passive eBay
Pros: High-quality manufacturer measurements give preference scores of 3.14 standalone and 6.01 with an ideal subwoofer. It is a 3-way design with a coaxial 1.4-inch mid/high driver above a low-distortion 12-inch woofer, rated at 98dB sensitivity and a very high 143dB peak. A rotatable 90° x 60° waveguide and passive or bi-amp operation suit both portable and installed systems. Measured bass extension of 85Hz (-3dB).
Cons: Bass measures 85Hz at -3dB and about 52Hz at -10dB, so a subwoofer is needed for full-range music. A 3.4dB reference band and 4.40 directivity-index deviation mean tonal balance varies more than in the smoothest 12-inch cabinets here. It is passive, weighs 21.5kg and is sold through pro dealers with no published price.
