Short answer: these RCF ART 945-A and RCF ART 735-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 735-A MK4. Its large 3-inch compression-driver voice coil, 132dB claimed peak and roughly 53Hz measured extension give it useful vocal headroom and bass reach. The 21.4kg enclosure remains manageable 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 eclipsed by current 9-series and MK5 models.
Buy the RCF ART 945-A when its stated coverage, output, processing, and deployment format best match the job.
Buy the RCF ART 735-A MK4 when its stated strengths are the better match for the room and the rest of the PA.
If sound quality matters at all to you, skip the RCF ART 735-A MK4. It ranks near the bottom of the 29 15-inch two-way powered pa speakers, so look higher up the list instead.
