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 RCF ART 745-A MK4 is discontinued; its replacement is the RCF ART 745-A MK5.
The case for the Vue Audiotechnik A-15. Low-quality vendor data shows a 4.57 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 41.4 lbs (18.8 kg) 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.

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.
