Short answer: the Coda Audio G515, if you are buying new. The Turbosound NuQ152 measures as well as it (#24 vs #27 of 76 15-inch pa speakers, 3.7/5 vs 3.7/5) but is discontinued, so only consider it used; the Coda Audio G515 is still sold new at $2,845.
The Turbosound NuQ152 is the more accurate, deeper-bass pick. A passive 15 inch PA speaker with fairly deep bass and high sensitivity, so modest amps play it loud. Its measured preference score, a predictor of how neutral it sounds, is 3.99 against 3.03 for the Coda Audio G515. Its bass reaches about 65Hz before falling 3dB, against 77.5Hz for the Coda Audio G515. The tradeoff: The Spinorama data is low quality, so the measured curves should be treated cautiously.
What the Coda Audio G515 does well: A light passive 15 inch PA speaker with high sensitivity and rotatable coverage for flexible full range use. The catch: The wide 3.8dB reference band means tonal balance is less even than the best 15-inch speakers.
Buy the Coda Audio G515, since the Turbosound NuQ152 is discontinued and only worth hunting down used.
