Short answer: choose between the QSC K8.2 and RCF ART 708-A MK5 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 7.74 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 MK5. A compact, affordable RCF with a 1.4-inch compression driver, 128dB claimed output and FiRPHASE processing, well suited to buyers who plan to cross to a subwoofer and do not need app control. At 22.9 lbs (10.4 kg) it is easy to carry.
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 local low-quality manufacturer data has no computed preference score, making its measured tonal position uncertain.
Buy the QSC K8.2 when its stated coverage, output, processing, and deployment format best match the job.
Buy the RCF ART 708-A MK5 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.
