These sit in different size classes, so this is not a straight ranking comparison. The Coda Audio G308 ranks #23 of 44 8-inch pa speakers by sound quality; the Coda Audio G515 ranks #21 of 61 15-inch pa speakers by sound quality.
Why pick the Coda Audio G308: The 8-inch model of Coda’s G-Series multidesign boxes, smaller than the measured Coda Audio G512 and Coda Audio G515. Watch for: No independent measurements yet, so it can’t be compared with ranked PA speakers.
What the Coda Audio G515 does well: High-quality manufacturer measurements give preference scores of 3.03 standalone and 5.90 with an ideal subwoofer. The tradeoff: The wide 3.8dB reference band means tonal balance is less even than the best 15-inch speakers.
Buy the Coda Audio G308 if you want a 8-inch pa speaker. Buy the Coda Audio G515 if you want a 15-inch pa speaker instead.
About the ratings: the Coda Audio G308’s rating is estimated from measured siblings and predecessors rather than its own measurements, with a likely range of 3.1 to 3.9, so this verdict could change once it is measured.

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 G515 Passive eBay
Same family: the Coda Audio G308 (smaller model, estimated 3.5/5), the Coda Audio G512 (smaller model, rated 3.6/5), the Coda Audio G712 (larger model, rated 3.8/5) and the Coda Audio G715 (larger model, ranked higher, rated 3.8/5).
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 Coda Audio 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.
