Short answer: choose between the RCF NX 915-A and Vue Audiotechnik A-15 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 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.
The case for the Vue Audiotechnik A-15. Low-quality vendor data shows a 3.83 ideal-subwoofer preference score, and the passive point-source design keeps amplification and DSP choices flexible for installers building out a system.
Important trade-offs. The truncated vendor measurement does not yield a preference score, preventing a confident tonal comparison with the scored leaders. At 24.1kg it is notably heavier than the ART-series alternatives. Measured bass extension is shallow at roughly 118Hz, so a subwoofer is effectively mandatory.
Buy the RCF NX 915-A when its stated format, coverage, and system features fit the job better.
Buy the Vue Audiotechnik A-15 when its stated output, control, and deployment strengths better match the system.

Vue Audiotechnik A-15: $2,500.00 eBay
Pros: Low-quality vendor data shows a 3.83 ideal-subwoofer preference score, and the passive point-source design keeps amplification and DSP choices flexible for installers building out a system.
Cons: Being passive, it needs an external amplifier and processing to perform correctly, adding cost and complexity that self-powered rivals avoid. Measured bass extension is shallow at roughly 118Hz, so a subwoofer is effectively mandatory.
