Short answer: these RCF KX 45-A and RCF ART 935-A 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 KX 45-A. RCF’s flagship 15-inch point source pairs a 3200W amplifier with a 3-inch titanium-dome compression driver, RDNet remote control and a 137dB claimed peak, the highest maximum-output claim in this ranking. Rotatable 100° x 70° coverage suits both main and monitor use.
Why choose the RCF ART 935-A. The bigger-voice-coil compression driver, 133dB claimed peak and broad 100° x 60° coverage mirror the well-regarded ART 932-A’s design in a 15-inch cabinet. At 53.4 lbs (24.2 kg) it stays manageable for a box this size.
What to weigh before buying. The local measurement is truncated and cannot produce a preference score. At 62.6 lbs (28.4 kg) it is one of the heaviest boxes here, and pricing/retail availability are not yet established. The low-quality vendor measurement is truncated and cannot generate a preference score, so its tonal position relies on published engineering and its 12-inch sibling’s reputation rather than a confirmed result.
Buy the RCF KX 45-A when its stated coverage, output, processing, and deployment format best match the job.
Buy the RCF ART 935-A 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.
