Short answer: choose between the JBL PRX908 and RCF ART 945-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 PRX908. High-quality vendor data shows a 4.95 ideal-subwoofer preference score with 58Hz measured extension, backed by JBL’s extensive service network. A 12-band parametric EQ with dbx DriveRack feedback suppression and BLE app control carry over the PRX900 series’ engineering into an 8-inch cabinet.
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.
What to weigh before buying. Its 126dB peak claim is modest for a main speaker, so pairing with a subwoofer matters more here than with the larger PRX modules. 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.
Buy the JBL PRX908 when its stated coverage, output, processing, and installation format fit the job better.
Buy the RCF ART 945-A when its stated strengths better suit the venue and the rest of the system.
