Short answer: the ART 715-A MK5 for a lighter, more affordable option, the NX 915-A for a sturdier systems build. These are two tiers of RCF 15-inch powered speaker, ranked #16 and #17 of 29, priced $842 apart.
The NX 915-A is the sturdier, wider-coverage build. Its plywood enclosure, FiRPHASE and Bass Motion Control processing and flexible rigging make it a sturdier systems alternative to the ART 715-A MK5, with a wider 100° x 60° pattern against the ART’s 90° x 60°, and a slightly higher 131dB claimed peak versus 130dB. It is also considerably heavier at 24.1kg against the ART 715-A MK5’s 19.6kg.
Neither has a computed preference score. The ART 715-A MK5’s local low-quality manufacturer data has no computed preference score, making its measured tonal position uncertain, and the NX 915-A’s truncated vendor measurement does not yield one either, so neither model allows a confident tonal comparison with the scored leaders in this size class. Both run PP composite or polyurea-coated plywood construction with M10-class rigging and neither offers app control or Bluetooth.
Buy the ART 715-A MK5 if you want a lighter, more affordable RCF 15-inch box for straightforward subwoofer-paired use.
Buy the NX 915-A if you want the sturdier plywood build and wider coverage pattern for systems-oriented installs.

Pros: A compact, affordable RCF with 130dB claimed output and FiRPHASE processing, extending the well-regarded ART 712-A MK5’s simple, subwoofer-paired design to a 15-inch woofer for deeper reach.
Cons: The local low-quality manufacturer data has no computed preference score, making its measured tonal position uncertain. The smaller compression-driver assembly offers less vocal headroom than the ART 735-A MK5.
