Short answer: the Yamaha DZR315. Both are rated 3.8/5 for sound quality (#21 and #19 of 76 15-inch pa speakers), and the Yamaha DZR315 costs $1,884.99 against $4,125 for the Coda Audio G715, and with sound quality even, the cheaper one is the better buy.
The Coda Audio G715 is the more accurate pick. A loud three way passive 15 inch PA speaker with a coaxial mid and high driver and rotatable coverage for touring. Its measured preference score, a predictor of how neutral it sounds, is 2.86 against 1.93 for the Yamaha DZR315. 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 case for the Yamaha DZR315: A powered three way 15 inch PA speaker with very high output and full DSP with a screen, able to cover a large room alone. 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.
Buy the Yamaha DZR315. Both are rated the same for sound quality, and it costs $2,240.01 less than the Coda Audio G715.
