Short answer: choose between the JBL PRX915 and RCF NX 915-A by matching the speaker to the deployment rather than treating their ranking positions as a universal verdict. Coverage, cabinet format, bass extension, output capability, DSP, and service support all matter in a PA system.
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 NX 915-A. The plywood enclosure, FiRPHASE/Bass Motion Control processing and flexible rigging make it a sturdier systems alternative to the ART 715-A MK5, with a wide 100° x 60° pattern and 131dB claimed peak.
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 truncated vendor measurement does not yield a preference score, preventing a confident tonal comparison with the scored leaders. At 24.1kg it is notably heavier than the ART-series alternatives.
Buy the JBL PRX915 when its stated coverage, output, processing, and installation format fit the job better.
Buy the RCF NX 915-A when its stated strengths better suit the venue and the rest of the system.
