Short answer: choose between the JBL PRX908 and RCF ART 935-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 5.69 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 935-A. The bigger-voice-coil compression driver, 133dB claimed peak and broad 100° x 60° coverage mirror the well-regarded ART 932-A’s design in a 15-inch cabinet. At 53.4 lbs (24.2 kg) it stays manageable for a box this size.
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 low-quality vendor measurement is truncated and cannot generate a preference score, so its tonal position relies on published engineering and its 12-inch sibling’s reputation rather than a confirmed result.
Buy the JBL PRX908 when its stated coverage, output, processing, and installation format fit the job better.
Buy the RCF ART 935-A when its stated strengths better suit the venue and the rest of the system.

Frequency Response Compared
Both speakers’ spinorama measurements, overlaid. A flatter line is more neutral: peaks sound forward or harsh, dips sound recessed. Each curve is shifted so its average from 300 Hz to 3 kHz sits at 0 dB, so loudness differences between the two are removed and only the shape is compared.
