Short answer: the DZR15 for most buyers, the EX15 if you specifically want its class-leading measured bass extension. These rank #11 and #12 out of 76 15-inch powered PA speakers, priced at $6,000 and $1,519.99, a $4,480.01 difference.
The EX15 measures the deepest bass of any 15-inch box in this ranking, at a specialist price. Medium-quality vendor data gives it a 4.83 ideal-subwoofer preference score with 42Hz measured extension, the deepest bass reach of any 15-inch box in this ranking. Its 3-inch-diaphragm compression driver and integrated DSP target vocal clarity and controlled throw, but at a roughly $6,000 asking price this specialist box is far less accessible than the mainstream leaders, and user controls are comparatively spare without an onboard mixer or app control.
The DZR15 costs a fraction as much and still measures close behind. Medium-quality vendor data returns a 5.25 preference score with 39Hz measured extension (from truncated manufacturer data that should be read cautiously), deeper than the DZR12. The bi-amped 2-inch compression driver and sophisticated onboard DSP target serious main-speaker duty, though it lacks Bluetooth audio and app control, and at this price it competes with systems-grade alternatives from RCF and HK Audio.
Buy the DZR15 for a strong measured result at a much lower price, with bi-amped DSP for serious main-speaker use.
Buy the EX15 if the class-leading measured bass extension and vocal-focused compression driver are worth the $4,480.01 premium to you.

Frequency Response Compared
Both speakers’ spinorama measurements, overlaid. A flatter line is more neutral: peaks sound forward or harsh, dips sound recessed. Each curve is shifted so its average from 300 Hz to 3 kHz sits at 0 dB, so loudness differences between the two are removed and only the shape is compared.
