Short answer: these RCF ART 745-A MK4 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 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.
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.
