Short answer: choose between the QSC K12.2 and RCF ART 732-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 RCF ART 732-A MK4 is discontinued; its replacement is the RCF ART 732-A MK5.
Why choose the QSC K12.2. The strongest all-round tonal result in this popular-model group: the vendor Spinorama data produces a 7.73 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 732-A MK4. Its large 3-inch compression-driver voice coil, 131dB claimed peak and roughly 53Hz measured extension give it useful vocal headroom and more bass reach than the 712 MK4. The 39.2 lbs (17.8 kg) enclosure remains easy to carry.
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 data is truncated and does not yield a preference score. It is discontinued, lacks modern remote control and is eclipsed by the better-supported ART 732-A MK5 and current 9-series models.
Buy the QSC K12.2 when its stated coverage, output, processing, and installation format fit the job better.
Buy the RCF ART 732-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.
