Short answer: choose between the RCF ART 745-A MK5 and LD Systems Stinger 15-A-G3 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 ART 745-A MK5. The top of the ART7 range pairs 133dB claimed peak output with a light 18.8kg enclosure, RCF’s largest ART7-tier compression driver and FiRPHASE processing carried over from the smaller 712/732-A MK5 models.
The case for the LD Systems Stinger 15-A-G3.
Important trade-offs. The low-quality vendor measurement is truncated and cannot generate a preference score, so its tonal position relies on published engineering rather than a confirmed result. The measured preference score is modest, and its 90° x 50° horn is narrower than several higher-scoring competitors. At 26.8kg it is one of the heavier budget-tier boxes here.
Buy the RCF ART 745-A MK5 when its stated format, coverage, and system features fit the job better.
Buy the LD Systems Stinger 15-A-G3 when its stated output, control, and deployment strengths better match the system.

Pros: Medium-quality vendor data shows a 3.58 ideal-subwoofer preference score with 39Hz measured extension, the deepest bass reach of any RCF-priced alternative in this tier, at an affordable price for a 15-inch active box.
Cons: The measured preference score is modest, and its 90° x 50° horn is narrower than several higher-scoring competitors. At 26.8kg it is one of the heavier budget-tier boxes here.
