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 41.4 lbs (18.8 kg) enclosure, RCF’s largest ART7-tier compression driver and FiRPHASE processing carried over from the smaller 712/732-A MK5 models.
The LD Systems Stinger 15-A-G3 is the deeper-bass choice. An affordable powered 15 inch PA speaker with two mic/line inputs and unusually deep bass reach for its price class. Its bass reaches about 41.2Hz before falling 3dB, against 65Hz for the RCF ART 745-A MK5. It has a microphone input for karaoke or announcements, which the RCF ART 745-A MK5 lacks. The tradeoff: The measured preference score is modest, and its 90° x 50° horn is narrower than several higher-scoring competitors.
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 59.1 lbs (26.8 kg) 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.

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.
