Short answer: choose between the JBL PRX908 and RCF ART 708-A MK5 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 708-A MK5. A compact, affordable RCF with a 1.4-inch compression driver, 128dB claimed output and FiRPHASE processing, well suited to buyers who plan to cross to a subwoofer and do not need app control. At 10.4kg it is easy to carry.
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. The local low-quality manufacturer data has no computed preference score, making its measured tonal position uncertain.
Buy the JBL PRX908 when its stated coverage, output, processing, and installation format fit the job better.
Buy the RCF ART 708-A MK5 when its stated strengths better suit the venue and the rest of the system.
Skip the RCF ART 708-A MK5 if sound quality matters to you. It ranks near the bottom of the 15 8-inch two-way powered pa speakers.
