Short answer: the Coda Audio G715. It ranks #14 of 38 15-inch pa speakers by sound quality (rated 3.8/5); the Turbosound NuQ152 ranks #17 (rated 3.7/5).
What the Coda Audio G715 does well: 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 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.
What the Turbosound NuQ152 does well: 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 tradeoff: The Spinorama data is low quality, so the measured curves should be treated cautiously.

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.

Turbosound NuQ152 Passive B&H Photo Video eBay
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.
