Short answer: the KV2 Audio EX12 if sound quality matters most, the RCF ART 712-A MK4 if price matters most. The KV2 Audio EX12 ranks #4 of 37 12-inch two-way powered pa speakers at $3480. The RCF ART 712-A MK4 ranks #35 at $509, $2971 cheaper.
What the KV2 Audio EX12 offers: A 5.83 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. Watch for: The 27.4kg enclosure and premium price make it much less portable and accessible than the mainstream leaders. User controls are comparatively spare, without an onboard mixer, app control or general-purpose parametric EQ.
What the RCF ART 712-A MK4 offers: 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. Watch for: 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.
Buy the KV2 Audio EX12 when sound quality outweighs the price for you, and the RCF ART 712-A MK4 when the price outweighs sound quality instead.
If sound quality matters at all to you, skip the RCF ART 712-A MK4. It ranks near the bottom of the 37 12-inch two-way powered pa speakers, so look higher up the list instead.
