Short answer: choose between the Yamaha DXR8mkII and RCF KX 08-A by matching the speaker to the deployment rather than treating their ranking positions as a universal verdict. Coverage, cabinet format, bass extension, output capability, DSP, and service support all matter in a PA system.
Why choose the Yamaha DXR8mkII. Medium-quality vendor data shows a 5.89 ideal-subwoofer preference score with 64Hz measured extension, among the strongest results here. Yamaha’s FIR-X processing, a 1.75-inch neodymium compression driver and a 90° x 60° constant-directivity horn carry over the larger DXR models’ engineering into a compact cabinet.
Why choose the RCF KX 08-A. The entry point into RCF’s flagship KX point-source range, with a 2000W amplifier, a PKX-dome neodymium compression driver, RDNet remote control and a rotatable 90° x 70° horn in a manageable 27.6 lbs (12.5 kg) cabinet.
What to weigh before buying. No mkIII successor exists for this size yet, so it is the oldest design generation in this ranking’s Yamaha lineup, without app control or Bluetooth audio. The local measurement is truncated and cannot produce a preference score, and pricing/retail availability are not yet well established for this model.
Buy the Yamaha DXR8mkII when its stated coverage, output, processing, and installation format fit the job better.
Buy the RCF KX 08-A when its stated strengths better suit the venue and the rest of the system.

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.
