Short answer: the Yamaha DZR315. Both are rated 3.8/5 for sound quality (#21 and #18 of 76 15-inch pa speakers), and the Yamaha DZR315 costs $1,884.99 against $1,990 for the Axiom ED150A, so with nothing between them on sound quality, price settles it.
What the Yamaha DZR315 does well: 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.
The Axiom ED150A is the more accurate, deeper-bass pick. A powered 15 inch PA speaker with good sound, deep bass and an asymmetric pattern that spreads sound evenly over an audience. Its measured preference score, a predictor of how neutral it sounds, is 3.14 against 1.93 for the Yamaha DZR315. Its bass reaches about 54.5Hz before falling 3dB, against 82.5Hz for the Yamaha DZR315. The catch: Axiom has a much smaller North American dealer and service network than JBL, Yamaha or QSC, and detailed coverage/weight figures were not confirmed in local data.
Buy the Yamaha DZR315. Both are rated the same for sound quality, and it costs $105.01 less than the Axiom ED150A.
