Short answer: choose between the QSC K10.2 and RCF NX 910-A for the requirements of the venue and system, not from rank alone. In this size class, coverage, bass extension, output capability, DSP, cabinet construction, and service support often decide the better fit.
Why choose the QSC K10.2. This is the standout measured result in this ranking: medium-quality vendor data returns a 8.25 ideal-subwoofer preference score, even higher than the well-regarded K12.2’s own result. Extensive onboard DSP, a 1.4-inch titanium compression driver and QSC’s long market track record make it an unusually safe general-purpose 10-inch pick.
Why choose the RCF NX 910-A. The plywood enclosure and FiRPHASE/Bass Motion Control processing make it a sturdier systems alternative to the ART 710-A MK5, with a wide 100° x 60° pattern and 130dB claimed peak.
What to weigh before buying. The underlying Spinorama source is low quality, so its apparent measured lead deserves some caution. Its 130dB peak claim is modest next to some 10-inch rivals, and a subwoofer still matters for full-range music at event levels. The truncated vendor measurement does not yield a preference score, preventing a confident tonal comparison with the scored leaders. At 36.2 lbs (16.4 kg) it is heavier than the ART-series alternative.
Buy the QSC K10.2 when its stated coverage, output, processing, and deployment format best match the job.
Buy the RCF NX 910-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.
