Short answer: choose between the QSC K12.2 and Yamaha DXR12mkIII 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 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 Yamaha DXR12mkIII. The third-generation DXR raises claimed output to 134dB and adds 2000W amplification, app-based control and more capable onboard DSP while staying light at 38.4 lbs (17.4 kg). Medium-quality vendor data shows measured extension around 60Hz.
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 truncated Spinorama data does not produce a preference score, so its tonal advantage over the proven DXR12mkII is not yet quantified. Wireless connectivity is for remote control, not a substitute for a wired production-audio input.
Buy the QSC K12.2 when its stated coverage, output, processing, and deployment format best match the job.
Buy the Yamaha DXR12mkIII 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.
