Short answer: these RCF ART 945-A and RCF ART 715-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. The RCF ART 715-A MK4 is discontinued; its replacement is the RCF ART 715-A MK5.
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 715-A MK4. The 43.2 lbs (19.6 kg) cabinet combines 130dB claimed peak output, a broad horn and RCF’s FiRPHASE processing in a straightforward, affordable package 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 measurement is truncated and cannot produce a reliable preference score.
Buy the RCF ART 945-A when its stated coverage, output, processing, and deployment format best match the job.
Buy the RCF ART 715-A MK4 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.
