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 G715 ranks #14 of 61 15-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 tradeoff: No independent measurements yet, so it can’t be compared with ranked PA speakers.
The case for the Coda Audio G715: High-quality manufacturer measurements give preference scores of 2.86 standalone and 5.88 with an ideal subwoofer, with a tighter 2.9dB reference band than the Coda Audio G515. The tradeoff: Bass measures 87.5Hz at -3dB and about 56.5Hz at -10dB, less extended than a 15-inch woofer suggests, so it still needs a subwoofer.
Buy the Coda Audio G308 if you want a 8-inch pa speaker. Buy the Coda Audio G715 if you want a 15-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 G715 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 G515 (smaller model, ranked lower, rated 3.7/5) and the Coda Audio G712 (smaller model, rated 3.8/5).
Pros: High-quality manufacturer measurements give preference scores of 2.86 standalone and 5.88 with an ideal subwoofer, with a tighter 2.9dB reference band than the Coda Audio G515. The 3-way design pairs a 15-inch low-distortion woofer with a coaxial 1.4-inch mid/high driver, rated at 98dB sensitivity and a 143dB peak. Passive or bi-amp operation and a rotatable 90° x 60° waveguide suit large venues and touring. Measured bass extension of 87.5Hz (-3dB).
Cons: Bass measures 87.5Hz at -3dB and about 56.5Hz at -10dB, less extended than a 15-inch woofer suggests, so it still needs a subwoofer. A 4.19 directivity-index deviation means off-axis tone varies. It weighs 24.5kg, is passive, and is sold through pro dealers with no published price.
