Short answer: a tie on sound quality. Both are rated 3.8/5 (#14 and #16 of 38 15-inch pa speakers), so choose on features and fit.
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 G515. The catch: 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.
The case for the Yamaha DZR315: A 3-way design with a 15-inch woofer, 8-inch midrange and 2-inch compression driver, powered by a 2000W bi-amp and rated to 143dB, so it covers a large room on its own. The catch: A 4.4dB reference band and a 7.19 directivity-index deviation mean tonal balance and off-axis consistency are uneven, and the standalone preference score is only 1.93.

The Two Speakers In Full
Coda Audio G715 Passive eBay
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 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.

Yamaha DZR315: $1,829.99 B&H Photo Video eBay
Pros: A 3-way design with a 15-inch woofer, 8-inch midrange and 2-inch compression driver, powered by a 2000W bi-amp and rated to 143dB, so it covers a large room on its own. Manufacturer measurements give a 5.06 preference score with an ideal subwoofer, and bass reaches 82.5Hz at -3dB and about 65Hz at -10dB. Onboard FIR DSP with an LCD screen handles presets, PEQ, delay and routing, with two combo inputs. Measured bass extension of 82.5Hz (-3dB).
Cons: A 4.4dB reference band and a 7.19 directivity-index deviation mean tonal balance and off-axis consistency are uneven, and the standalone preference score is only 1.93. It is large and expensive next to the 2-way DZR15.
