Short answer: the Coda Audio G715. It ranks #19 of 76 15-inch pa speakers by sound quality (rated 3.8/5) at $4,125 and is still sold new; the Turbosound NuQ152 ranks #24 (rated 3.7/5) and is discontinued, so it is only an option used.
What the Coda Audio G715 does well: A loud three way passive 15 inch PA speaker with a coaxial mid and high driver and rotatable coverage for touring. 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.
The Turbosound NuQ152 is the more accurate, deeper-bass option. 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 2.86 for the Coda Audio G715. Its bass reaches about 65Hz before falling 3dB, against 87.5Hz for the Coda Audio G715. The catch: The Spinorama data is low quality, so the measured curves should be treated cautiously.
Buy the Coda Audio G715. It is rated higher for sound quality; the Turbosound NuQ152 is no longer sold new.
