Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The Coda Audio G308 ranks #23 of 44 8-inch pa speakers by sound quality; the Coda Audio G512 ranks #38 of 77 12-inch pa speakers by sound quality.
What the Coda Audio G308 does well: The 8-inch model of Coda’s G-Series multidesign boxes, smaller than the measured Coda Audio G512 and Coda Audio G515. The catch: No independent measurements yet, so it can’t be compared with ranked PA speakers.
What the Coda Audio G512 does well: High-quality vendor Spinorama data gives preference scores of 3.04 standalone and 6.11 with an ideal subwoofer. The catch: 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.
Buy the Coda Audio G308 for a 8-inch pa speaker; the Coda Audio G512 suits a 12-inch pa speaker instead.
Worth knowing: the Coda Audio G308 has not been measured yet. Its rating is estimated from related models, with a likely range of 3.1 to 3.9, so treat this verdict as provisional.

Coda Audio G308 Passive Estimated eBay
Same family: the Coda Audio G512 (larger model, rated 3.6/5), the Coda Audio G515 (larger model, rated 3.7/5), the Coda Audio G712 (larger model, rated 3.8/5) and the Coda Audio G715 (larger model, rated 3.8/5).
Pros: The 8-inch model of Coda’s G-Series multidesign boxes, smaller than the measured Coda Audio G512 and Coda Audio G515. An 8” low-distortion woofer and a 1” compression driver on a 90° conical wooden waveguide cover 60Hz to 30kHz (-6dB) with 220W AES handling, and the cabinet works upright, on its side or as a floor monitor.
Cons: No independent measurements yet, so it can’t be compared with ranked PA speakers. It needs an external amplifier and controller and is sold only through Coda dealers, so there is no retail price.

Coda Audio G512 Passive eBay
Same family: the Coda Audio G308 (smaller model, estimated 3.5/5), the Coda Audio G515 (larger model, rated 3.7/5), the Coda Audio G712 (larger model, ranked higher, rated 3.8/5) and the Coda Audio G715 (larger model, rated 3.8/5).
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.
