Short answer: choose between the QSC K12.2 and KV2 Audio EX12 for the deployment, not from the automatic ranking alone. Their driver format, power requirements, coverage, bass reach, output capability, and control features determine which is the more practical PA for a particular room or system.
The case for 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.
The case for the KV2 Audio EX12. A 6.62 ideal-subwoofer preference score and 52Hz bass extension from medium-quality vendor data make this one of the strongest measured specialist boxes. Its 3-inch-diaphragm compression driver, 133dB claimed peak and 80° x 40° horn target high vocal clarity and controlled throw.
Important trade-offs. 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. User controls are comparatively spare, without an onboard mixer, app control or general-purpose parametric EQ.
Buy the QSC K12.2 when its stated format, coverage, and system features fit the job better.
Buy the KV2 Audio EX12 when its stated output, control, and deployment strengths better match 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.
