Short answer: choose between the RCF ART 945-A and Yamaha DZR15 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 RCF ART 945-A. This is the strongest-measuring 15-inch RCF here: medium-quality vendor data produces a 6.69 ideal-subwoofer preference score with roughly 50Hz extension. The top-tier compression driver and 41.4 lbs (18.8 kg) enclosure combine unusually high output with easy portability for a 15-inch box.
Why choose the Yamaha DZR15. Medium-quality vendor data returns a 5.25 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.
What to weigh before buying. Pricing and wide retail distribution are not yet well established for this model, and the RCF ART9 range above the 912/932-A pair has a shorter market track record. Coverage and full connector details were not confirmed in local data. The bass-extension figure comes from truncated manufacturer data and should be read cautiously.
Buy the RCF ART 945-A when its stated coverage, output, processing, and deployment format best match the job.
Buy the Yamaha DZR15 when its stated strengths are the better match for the room and the rest of the PA.

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. The two were measured by different sources, so small differences, especially in the bass, can come from the measurement setup rather than the speakers.
