Short answer: these RCF ART 945-A and RCF ART 745-A MK5 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 6.69 ideal-subwoofer preference score with roughly 50Hz extension. The top-tier compression driver and 41.4 lbs (18.8 kg) enclosure combine unusually high output with easy portability for a 15-inch box.
Why choose 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.
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 measurement is truncated and cannot generate a preference score, so its tonal position relies on published engineering rather than a confirmed result.
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 MK5 when its stated strengths are the better match for the room and the rest of the PA.

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. The two were measured by different sources, so small differences, especially in the bass, can come from the measurement setup rather than the speakers.
