Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The Coda Audio G515 ranks #20 of 40 15-inch pa speakers by sound quality; the Coda Audio G512 ranks #34 of 54 12-inch pa speakers by sound quality.
The Coda Audio G515 is the deeper-bass choice. High-quality manufacturer measurements give preference scores of 3.03 standalone and 5.90 with an ideal subwoofer. Its bass reaches about 77.5Hz before falling 3dB, against 112Hz for the Coda Audio G512. The catch: The wide 3.8dB reference band means tonal balance is less even than the best 15-inch speakers.
The case for the Coda Audio G512: High-quality vendor Spinorama data gives preference scores of 3.04 standalone and 6.11 with an ideal subwoofer. Watch for: 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.

Coda Audio G515 Passive eBay
Pros: High-quality manufacturer measurements give preference scores of 3.03 standalone and 5.90 with an ideal subwoofer. The 15-inch neodymium woofer reaches 77.5Hz at -3dB and about 53Hz at -10dB, and the cabinet weighs just 17.5kg. A 98dB sensitivity, 132dB peak rating and rotatable 90° x 60° waveguide make it a light, flexible full-range box. Measured bass extension of 77.5Hz (-3dB).
Cons: The wide 3.8dB reference band means tonal balance is less even than the best 15-inch speakers. Output is lower than its 3-way G715 sibling, and a 4.06 directivity-index deviation means off-axis tone varies. It is passive and sold through pro dealers with no published price.

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.
