RCF NX 945-A vs RCF ART 735-A MK4

Short answer: these RCF NX 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 NX 945-A. The top NX-series 15-inch box pairs a plywood cabinet with a 135dB claimed peak, the highest in the NX range, and a wide 100° x 70° pattern. RCF’s FiRPHASE and Bass Motion Control processing carry over from the smaller NX models.

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. The measurement is truncated and does not produce a preference score, so its tonal position relies on published engineering rather than a confirmed result. At 27.3kg it is heavier than the ART 945-A alternative. 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 NX 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.

The RCF ART 735-A MK4 is not a sound-quality pick. It sits near the bottom of the 29 15-inch two-way powered pa speakers; there are better options higher up.
