Short answer: the QSC K12.2. It ranks #1 of 50 12-inch pa speakers by sound quality (rated 4.7/5); the Martin Audio CDD12 ranks #48 (rated 2.9/5).
Why pick 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. Watch for: The underlying Spinorama source is low quality, so its apparent measured lead deserves caution.
Why pick the Martin Audio CDD12: Martin Audio’s Coaxial Differential Dispersion driver widens horizontal coverage from 60° far away to 110° up close, so level stays more even from front row to back. The tradeoff: Manufacturer measurements give a very low 0.82 standalone preference score and 3.80 with an ideal subwoofer, with a wide 4.0dB reference band and 0.821 listening-window deviation, so its tonal balance is very uneven.

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.

Martin Audio CDD12 Passive eBay
Pros: Martin Audio’s Coaxial Differential Dispersion driver widens horizontal coverage from 60° far away to 110° up close, so level stays more even from front row to back. A 12-inch woofer shares its motor with a 1-inch compression driver in a 19kg birch cabinet, available in any RAL color for installs. Measured bass extension of 95Hz (-3dB).
Cons: Manufacturer measurements give a very low 0.82 standalone preference score and 3.80 with an ideal subwoofer, with a wide 4.0dB reference band and 0.821 listening-window deviation, so its tonal balance is very uneven. Bass measures 95Hz at -3dB. It is passive, aimed at installs, and sold only through dealers.
