Short answer: the Yamaha DZR315. Both are rated 3.8/5 for sound quality (#16 and #13 of 38 15-inch pa speakers), and the Yamaha DZR315 costs $1,829.99 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 3-way design with a 15-inch woofer, 8-inch midrange and 2-inch compression driver, powered by a 2000W bi-amp and rated to 143dB, so it covers a large room on its own. 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.
What the Axiom ED150A does well: High-quality vendor data returns a 5.36 ideal-subwoofer preference score with 47Hz measured extension, matching the well-regarded ED120A’s asymmetric-coverage design in a 15-inch cabinet. The tradeoff: 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 $160.01 less than the Axiom ED150A.

The Two Speakers In Full
Yamaha DZR315: $1,829.99 B&H Photo Video eBay
Pros: A 3-way design with a 15-inch woofer, 8-inch midrange and 2-inch compression driver, powered by a 2000W bi-amp and rated to 143dB, so it covers a large room on its own. Manufacturer measurements give a 5.06 preference score with an ideal subwoofer, and bass reaches 82.5Hz at -3dB and about 65Hz at -10dB. Onboard FIR DSP with an LCD screen handles presets, PEQ, delay and routing, with two combo inputs. Measured bass extension of 82.5Hz (-3dB).
Cons: 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. It is large and expensive next to the 2-way DZR15.
