Short answer: choose between the Vue Audiotechnik A-15 and RCF ART 745-A MK4 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 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.
The case for the RCF ART 745-A MK4. The largest ART7 compression driver, 133dB claimed peak and a light 18.8kg enclosure give this discontinued flagship useful vocal headroom for a 15-inch box.
Important trade-offs. Measured bass extension is shallow at roughly 118Hz, so a subwoofer is effectively mandatory. The low-quality vendor data is truncated and does not yield a preference score. It is discontinued and is eclipsed by the better-supported ART 745-A MK5.
Buy the Vue Audiotechnik A-15 when its stated format, coverage, and system features fit the job better.
Buy the RCF ART 745-A MK4 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.
