Short answer: choose between the Yamaha DXR12mkII and RCF KX 45-A 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.
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 KX 45-A. RCF’s flagship 15-inch point source pairs a 3200W amplifier with a 3-inch titanium-dome compression driver, RDNet remote control and a 137dB claimed peak, the highest maximum-output claim in this ranking. Rotatable 100° x 70° coverage suits both main and monitor use.
What to weigh before buying. The 4.66 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 local measurement is truncated and cannot produce a preference score. At 28.4kg it is one of the heaviest boxes here, and pricing/retail availability are not yet established.
Buy the Yamaha DXR12mkII when its stated coverage, output, processing, and installation format fit the job better.
Buy the RCF KX 45-A when its stated strengths better suit the venue and the rest of the system.
