Short answer: choose between the JBL PRX915 and RCF ART 715-A MK5 for the requirements of the venue and system, not from rank alone. In this size class, coverage, bass extension, output capability, DSP, cabinet construction, and service support often decide the better fit.
Why choose the JBL PRX915. High-quality vendor data shows a 4.02 ideal-subwoofer preference score with 51Hz measured extension, backed by JBL’s extensive service network and 12-band parametric EQ with dbx DriveRack feedback suppression carried over from the PRX912.
Why choose the RCF ART 715-A MK5. A compact, affordable RCF with 130dB claimed output and FiRPHASE processing, extending the well-regarded ART 712-A MK5’s simple, subwoofer-paired design to a 15-inch woofer for deeper reach.
What to weigh before buying. Its measured preference trails the 12-inch PRX912, and at 24.1kg it is meaningfully heavier to carry to a gig than the smaller model. The local low-quality manufacturer data has no computed preference score, making its measured tonal position uncertain. The smaller compression-driver assembly offers less vocal headroom than the ART 735-A MK5.
Buy the JBL PRX915 when its stated coverage, output, processing, and deployment format best match the job.
Buy the RCF ART 715-A MK5 when its stated strengths are the better match for the room and the rest of the PA.
