Short answer: choose between the HK Audio LINEAR 5 112 FA and RCF HD 12-A MK5 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 The HK Audio LINEAR 5 112 FA has been replaced by the HK Audio Linear 5 MK2 112 FA. If you are buying new, get the HK Audio Linear 5 MK2 112 FA.
The case for the HK Audio LINEAR 5 112 FA. High-quality vendor data yields a 5.07 ideal-subwoofer preference score, while the asymmetric horn can cover wider near-field seating without wasting as much energy upward. The 135dB claimed peak gives it substantial headroom.
The case for the RCF HD 12-A MK5. Medium-quality vendor data indicates useful extension into the low 60Hz region.
Important trade-offs. The 70Hz measured bass extension points toward subwoofer use, and the 52.7 lbs (23.9 kg) cabinet is relatively heavy. This original LINEAR 5 generation lacks the deeper networked DSP and current support advantages of the newer MK2, LINEAR 7 and LINEAR 9 models. The truncated Spinorama measurement cannot produce a preference score, so tonal confidence is lower than for the fully scored leaders. Controls are intentionally simple and omit app control, networking and a multi-input mixer.
Buy the HK Audio LINEAR 5 112 FA when its stated format, coverage, and system features fit the job better.
Buy the RCF HD 12-A MK5 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.
