Short answer: choose between the Yamaha DZR15 and RCF ART 745-A MK4 for the requirements of the venue and system, not from rank alone. In this size class, coverage, bass extension, output capability, DSP, cabinet construction, and service support often decide the better fit.
Why choose the Yamaha DZR15. Medium-quality vendor data returns a 4.54 ideal-subwoofer preference score with 39Hz measured extension, deeper than the DZR12. The bi-amped 2-inch compression driver and sophisticated onboard DSP target serious main-speaker duty.
Why choose the RCF ART 745-A MK4. The largest ART7 compression driver, 133dB claimed peak and a light 18.8kg enclosure give this discontinued flagship useful vocal headroom for a 15-inch box.
What to weigh before buying. The bass-extension figure comes from truncated manufacturer data and should be read cautiously. The low-quality vendor data is truncated and does not yield a preference score. It is discontinued and is eclipsed by the better-supported ART 745-A MK5.
Buy the Yamaha DZR15 when its stated coverage, output, processing, and deployment format best match the job.
Buy the RCF ART 745-A MK4 when its stated strengths are the better match for the room and the rest of the PA.

Yamaha DZR15: $1,291.99 Amazon B&H Photo Video Guitar Center eBay
Pros: Medium-quality vendor data returns a 4.54 ideal-subwoofer preference score with 39Hz measured extension, deeper than the DZR12. The bi-amped 2-inch compression driver and sophisticated onboard DSP target serious main-speaker duty.
Cons: The bass-extension figure comes from truncated manufacturer data and should be read cautiously. It lacks Bluetooth audio and app control, and at this price competes with systems-grade alternatives from RCF and HK Audio.
