Short answer: choose between the JBL PRX915 and RCF ART 935-A for the deployment, not from the automatic ranking alone. Their driver format, power requirements, coverage, bass reach, output capability, and control features determine which is the more practical PA for a particular room or system.
The case for the JBL PRX915. High-quality vendor data shows a 4.77 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.
The case for 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.
Important trade-offs. Its measured preference trails the 12-inch PRX912, and at 53.1 lbs (24.1 kg) it is meaningfully heavier to carry to a gig than the smaller model. 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 PRX915 when its stated format, coverage, and system features fit the job better.
Buy the RCF ART 935-A when its stated output, control, and deployment strengths better match 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.
