Short answer: choose between the Yamaha DXR15mkII and RCF ART 745-A MK4 by matching the speaker to the deployment rather than treating their ranking positions as a universal verdict. Coverage, cabinet format, bass extension, output capability, DSP, and service support all matter in a PA system. The Yamaha DXR15mkII has been replaced by the Yamaha DXR15mkIII. The RCF ART 745-A MK4 has been replaced by the RCF ART 745-A MK5. If you are buying new, get the Yamaha DXR15mkIII.
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.
Why choose the RCF ART 745-A MK4. The largest ART7 compression driver, 133dB claimed peak and a light 41.4 lbs (18.8 kg) enclosure give this discontinued flagship useful vocal headroom for a 15-inch box.
What to weigh before buying. The preference score sits mid-pack for this ranking, and it lacks app control or Bluetooth audio found on some newer competitors. 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 DXR15mkII when its stated coverage, output, processing, and installation format fit the job better.
Buy the RCF ART 745-A MK4 when its stated strengths better suit the venue and the rest of the system.

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.
