Short answer: choose between the Turbosound NuQ82 and RCF KX 08-A for the deployment, not from the automatic ranking alone. Their driver format, power requirements, coverage, bass reach, output capability, and control features determine which is the more practical PA for a particular room or system.
The case for the Turbosound NuQ82. Low-quality vendor data still shows a 5.1 ideal-subwoofer preference score with 52Hz measured extension, the deepest bass reach of any 8-inch box in this ranking. The switchable passive/bi-amp design and coaxial point-source layout give installers flexibility on amplification and DSP.
The case for 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.
Important trade-offs. Being passive-by-default, it needs an external amplifier and crossover to work at all, and its 123dB peak claim trails every active speaker here. 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 Turbosound NuQ82 when its stated format, coverage, and system features fit the job better.
Buy the RCF KX 08-A when its stated output, control, and deployment strengths better match 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.
