Short answer: choose between the QSC K8.2 and RCF ART 708-A MK4 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 K8.2. This is the standout measured result in this ranking: low-quality vendor data still returns a 6.88 ideal-subwoofer preference score, continuing the K.2 series’ strong showing at every driver size. Extensive onboard DSP, a titanium compression driver and QSC’s long market track record make it an unusually safe general-purpose 8-inch pick.
Why choose the RCF ART 708-A MK4. The 10.4kg cabinet combines 127dB claimed peak output, a broad horn and RCF’s FiRPHASE processing in a straightforward, affordable package for an 8-inch box.
What to weigh before buying. The underlying Spinorama source is low quality, so its apparent measured lead deserves some caution. An 8-inch woofer means a subwoofer partner matters even more than with the larger K.2 models. The low-quality vendor measurement is truncated and cannot produce a reliable preference score.
Buy the QSC K8.2 when its stated coverage, output, processing, and deployment format best match the job.
Buy the RCF ART 708-A MK4 when its stated strengths are the better match for the room and the rest of the PA.
The RCF ART 708-A MK4 is not a sound-quality pick. It sits near the bottom of the 15 8-inch two-way powered pa speakers; there are better options higher up.

Cons: The low-quality vendor measurement is truncated and cannot produce a reliable preference score. This discontinued MK4 offers little reason to choose it over the newer ART 708-A MK5 unless the used price is substantially lower.
