Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The RCF ART 915-A ranks #22 of 76 15-inch pa speakers by sound quality at $1,049; the QSC K12.2 ranks #1 of 83 12-inch pa speakers by sound quality at $899.99.
Why pick the RCF ART 915-A: A powered 15 inch PA speaker with strong amplification and very deep rated bass, helpful for music without a subwoofer. The tradeoff: No independent measurements yet, so it can’t be compared with ranked PA speakers.
The case for the QSC K12.2: A reliable 12 inch PA speaker with excellent sound and flexible built in processing, a safe choice for most events. The catch: The underlying Spinorama source is low quality, so its apparent measured lead deserves caution.
Buy the RCF ART 915-A at $1,049 for a 15-inch pa speaker, or the QSC K12.2 at $899.99 for a 12-inch pa speaker instead.
About the ratings: the RCF ART 915-A’s rating is estimated from measured siblings and predecessors rather than its own measurements, with a likely range of 3.5 to 4.1, so this verdict could change once it is measured.
