Short answer: the KV2 Audio EX12 on measured sound quality, the RCF NX 912-A on price. The KV2 Audio EX12 ranks #5 of 83 12-inch pa speakers, rated 4.4/5, at $3,480. The RCF NX 912-A ranks #20, rated 4.0/5, at $1,449, $2,031 cheaper.
The KV2 Audio EX12 is the better-sounding option. A highly accurate specialist 12 inch PA speaker with deep bass, very clear vocals and controlled throw. The catch: The 60.4 lbs (27.4 kg) enclosure and premium price make it much less portable and accessible than the mainstream leaders.
The case for the RCF NX 912-A: A sturdy plywood 12 inch powered PA speaker with strong amplification, wide coverage and flexible rigging for professional systems. The tradeoff: The truncated vendor measurement does not yield a preference score, preventing a confident tonal comparison with the scored leaders.
Buy the KV2 Audio EX12 when sound quality outweighs the price for you, and the RCF NX 912-A when the price outweighs sound quality instead.
