Short answer: a tie on sound quality. Both are rated 3.7/5 (#17 and #20 of 38 15-inch pa speakers), so choose on features and fit.
Why pick the Turbosound NuQ152: Vendor Spinorama data gives preference scores of 3.99 standalone and 6.59 with an ideal subwoofer, and bass reaches about 65Hz (-3dB), deeper than most boxes on this ranking. The catch: The Spinorama data is low quality, so the measured curves should be treated cautiously.
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 catch: The wide 3.8dB reference band means tonal balance is less even than the best 15-inch speakers.
Buy the Turbosound NuQ152 or the Coda Audio G515 on features: they are rated the same for sound quality at close to the same price.

Pros: Vendor Spinorama data gives preference scores of 3.99 standalone and 6.59 with an ideal subwoofer, and bass reaches about 65Hz (-3dB), deeper than most boxes on this ranking. Sensitivity of 97dB means modest amplifiers reach high levels, and the 70° pattern is easy to place. Measured bass extension of 65Hz (-3dB).
Cons: The Spinorama data is low quality, so the measured curves should be treated cautiously. Predicted in-room smoothness of 0.438 is well behind the best 15-inch boxes, and as a passive cabinet it needs an external amplifier and processor to play at all.

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.
