Short answer: choose between the RCF KX 08-A and LD Systems Stinger 8-A-G3 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 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.
The case for the LD Systems Stinger 8-A-G3. Medium-quality vendor data returns a 5.20 ideal-subwoofer preference score with 49Hz measured extension, a genuinely deep result for an affordable 8-inch box. At 23.1 lbs (10.5 kg) it is one of the lightest active speakers in this ranking.
Important trade-offs. The local measurement is truncated and cannot produce a preference score, and pricing/retail availability are not yet well established for this model. Its 125dB peak claim is modest next to the higher-output rivals here, and its 90° x 50° horn is on the narrower side.
Buy the RCF KX 08-A when its stated format, coverage, and system features fit the job better.
Buy the LD Systems Stinger 8-A-G3 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.
