Short answer: choose between the Electro-Voice MFX-15MC and RCF NX 915-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 Electro-Voice MFX-15MC. Medium-quality vendor data returns a 5.01 ideal-subwoofer preference score with 67Hz measured extension, the strongest result of any coaxial monitor in this ranking. The coaxial 15-inch design gives compact 60° x 40° coverage and a claimed 135dB peak with recommended amplification.
The case for the RCF NX 915-A. The plywood enclosure, FiRPHASE/Bass Motion Control processing and flexible rigging make it a sturdier systems alternative to the ART 715-A MK5, with a wide 100° x 60° pattern and 131dB claimed peak.
Important trade-offs. This is not self-powered: it requires an external amplifier and can run passive or externally bi-amplified, so it is less convenient than every conventional powered cabinet here. The narrow pattern is aimed primarily at stage-monitor and short-throw fill use rather than wide-audience main duty. The truncated vendor measurement does not yield a preference score, preventing a confident tonal comparison with the scored leaders. At 53.1 lbs (24.1 kg) it is notably heavier than the ART-series alternatives.
Buy the Electro-Voice MFX-15MC when its stated format, coverage, and system features fit the job better.
Buy the RCF NX 915-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.
