Short answer: choose between the RCF KX 10-A and JBL PRX915 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 RCF KX 10-A. The entry point into RCF’s flagship KX point-source range, with a 130dB claimed peak, a neodymium woofer and wide 100° x 50° coverage in a manageable 15.5kg cabinet.
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.
What to weigh before buying. The local measurement is truncated and cannot produce a preference score, and pricing/retail availability are not yet well established for this model. 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.
Buy the RCF KX 10-A when its stated coverage, output, processing, and installation format fit the job better.
Buy the JBL PRX915 when its stated strengths better suit the venue and the rest of the system.
