Short answer: these RCF ART 945-A and RCF ART 745-A MK4 alternatives share a brand and size class, but their coverage, driver architecture, cabinet format, processing, and output priorities can make them fit very different jobs.
Why choose the RCF ART 945-A. This is the strongest-measuring 15-inch RCF here: medium-quality vendor data produces a 5.91 ideal-subwoofer preference score with roughly 50Hz extension. The top-tier compression driver and 18.8kg enclosure combine unusually high output with easy portability for a 15-inch box.
Why choose 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.
What to weigh before buying. Pricing and wide retail distribution are not yet well established for this model, and the RCF ART9 range above the 912/932-A pair has a shorter market track record. Coverage and full connector details were not confirmed in local data. 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 RCF ART 945-A when its stated coverage, output, processing, and deployment format best match the job.
Buy the RCF ART 745-A MK4 when its stated strengths are the better match for the room and the rest of the PA.
