Short answer: choose between the RCF ART 945-A and JBL PRX915 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 RCF ART 945-A. This is the strongest-measuring 15-inch RCF here: medium-quality vendor data produces a 5.91 ideal-subwoofer preference score with roughly 50Hz extension. The top-tier compression driver and 18.8kg enclosure combine unusually high output with easy portability for a 15-inch box.
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. Pricing and wide retail distribution are not yet well established for this model, and the RCF ART9 range above the 912/932-A pair has a shorter market track record. Coverage and full connector details were not confirmed in local data. 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 ART 945-A when its stated coverage, output, processing, and deployment format best match the job.
Buy the JBL PRX915 when its stated strengths are the better match for the room and the rest of the PA.
