Short answer: choose between the QSC K12.2 and RCF ART 712-A MK4 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 QSC K12.2. The strongest all-round tonal result in this popular-model group: the vendor Spinorama data produces a 6.82 ideal-subwoofer preference score and 48Hz measured bass extension. Extensive onboard DSP, flexible main/monitor use and a long market track record make it an unusually safe general-purpose choice.
Why choose the RCF ART 712-A MK4. The 17.8kg cabinet combines 129dB claimed peak output, a broad horn and RCF’s FiRPHASE processing in a straightforward package. Its measured response extends to roughly 65Hz before the first major roll-off.
What to weigh before buying. The underlying Spinorama source is low quality, so its apparent measured lead deserves caution. It is not the cheapest 12-inch option, and serious dance music or high-output live use still benefits from a subwoofer. The low-quality vendor measurement is truncated and cannot produce a reliable preference score.
Buy the QSC K12.2 when its stated coverage, output, processing, and deployment format best match the job.
Buy the RCF ART 712-A MK4 when its stated strengths are the better match for the room and the rest of the PA.
The RCF ART 712-A MK4 is not a sound-quality pick. It sits near the bottom of the 37 12-inch two-way powered pa speakers; there are better options higher up.

Cons: The low-quality vendor measurement is truncated and cannot produce a reliable preference score. This discontinued MK4 offers little reason to choose it over the newer ART 712-A MK5 unless the used price is substantially lower.
