Short answer: the JBL PRX915 has been measured and ranked among 15-inch pa speakers; the RCF ART 735-A MK5 has not been independently measured yet, so until it is, this comes down to features and price.
What the RCF ART 735-A MK5 offers: A 15” woofer and a 1.4” exit titanium compression driver with a 3” voice coil, powered by 1,400W peak (1,000W LF, 400W HF) with DSP crossover at 800Hz.
What the JBL PRX915 brings: 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 JBL PRX912.
On paper: The RCF ART 735-A MK5 is rated down to 45Hz against 48Hz, though makers quote these at different tolerances.
Price: the RCF ART 735-A MK5 lists at $999 and the JBL PRX915 at $1,099.

The Two Speakers In Full
RCF ART 735-A MK5: $999.00 Amazon B&H Photo Video eBay
Older model: the RCF ART 735-A MK4 (rated 3.2/5).
Pros: A 15” woofer and a 1.4” exit titanium compression driver with a 3” voice coil, powered by 1,400W peak (1,000W LF, 400W HF) with DSP crossover at 800Hz. RCF rates it at 45Hz to 20kHz and 132dB maximum output over 90° x 60° coverage. FiRPHASE phase alignment and XBOOST bass modes can be set from the rear panel or the LiveRemote app, and the mic/line input feeds an XLR link output.
Cons: No independent measurements yet, so its tonal balance and directivity can’t be compared with ranked speakers. At 21.4 kg it is heavy for one person to lift onto a pole, and it needs a subwoofer for deep bass at event levels.

JBL PRX915: $1,099.00 Amazon B&H Photo Video Guitar Center eBay
Pros: 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 JBL PRX912. Measured bass extension of 58Hz (-3dB).
Cons: Its measured preference trails the 12-inch JBL PRX912, and at 24.1kg it is meaningfully heavier to carry to a gig than the smaller model.
