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 #30 and #31 of 76, priced $892 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 53.1 lbs (24.1 kg) against the ART 715-A MK5’s 43.2 lbs (19.6 kg).
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.

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.
