Short answer: choose between the Yamaha DXR12mkII and RCF NX 912-A 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 DXR12mkII is discontinued; its replacement is the Yamaha DXR12mkIII. If you are buying new, get the Yamaha DXR12mkIII.
Why choose the Yamaha DXR12mkII. A proven, broadly distributed workhorse with a flexible three-channel input section and 134dB claimed maximum output. Medium-quality vendor Spinorama data and 61Hz measured extension provide more evidence than many PA competitors, while Yamaha’s FIR-X processing and D-CONTOUR presets simplify setup.
Why choose the RCF NX 912-A. The plywood enclosure, 2100W amplification, FiRPHASE/Bass Motion Control and flexible rigging make it a sturdier systems alternative to the ART 912-A. Medium-quality data indicates extension to roughly 58Hz with broad 100° x 60° coverage.
What to weigh before buying. The 5.49 ideal-subwoofer preference score is only mid-pack, with meaningful response/directivity irregularity in the supplied data. It lacks app control and Bluetooth audio, and newer competitors offer more user-adjustable DSP. The truncated vendor measurement does not yield a preference score, preventing a confident tonal comparison with the scored leaders. Its 130dB peak claim matches the cheaper ART 912-A rather than exceeding it.
Buy the Yamaha DXR12mkII when its stated coverage, output, processing, and deployment format best match the job.
Buy the RCF NX 912-A 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.
