Short answer: the RCF KX 32-A. It ranks #7 of 83 12-inch pa speakers by sound quality, rated 4.3/5, at $4,198.50; the KV2 Audio ESR212 ranks #11, rated 4.2/5, and costs $6,874, so there is not much of a tradeoff to weigh.
Why pick the RCF KX 32-A: A flagship 12 inch powered PA speaker with huge amplifier power, a large compression driver and smooth sound for demanding mains. Watch for: The measurement is truncated and cannot produce a preference score, while the 52 lbs (23.6 kg) plywood enclosure is heavier than mainstream molded alternatives.
The KV2 Audio ESR212 is the deeper-bass pick. A full range PA speaker with two 12 inch woofers and a dedicated midrange, deep enough to play music without a subwoofer. Its bass reaches about 40Hz before falling 3dB, against 61.5Hz for the RCF KX 32-A. The catch: The dual-woofer, 3-way cabinet is bulkier than a conventional 12-inch top.
Buy the RCF KX 32-A. It is rated higher for sound quality than the KV2 Audio ESR212 and costs less, which makes it the one to get unless you need something the other one does better.
