Short answer: choose between the RCF ART 945-A and Yamaha DXR15mkII 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. The Yamaha DXR15mkII is discontinued; its replacement is the Yamaha DXR15mkIII.
Why choose the RCF ART 945-A. This is the strongest-measuring 15-inch RCF here: medium-quality vendor data produces a 5.91 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 DXR15mkII. A proven, broadly distributed workhorse: medium-quality vendor data shows a 4.98 ideal-subwoofer preference score with 61Hz measured extension, and Yamaha’s FIR-X processing and D-CONTOUR presets simplify setup.
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 preference score sits mid-pack for this ranking, and it lacks app control or Bluetooth audio found on some newer competitors.
Buy the RCF ART 945-A when its stated coverage, output, processing, and deployment format best match the job.
Buy the Yamaha DXR15mkII 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.
