Short answer: choose between the HK Audio LINEAR 9 112 XA and Axiom ED120A 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 HK Audio LINEAR 9 112 XA. The high-quality vendor data returns a 5.66 ideal-subwoofer preference score. MILAN networking, comprehensive remote DSP and a durable plywood cabinet make it a strong systems-oriented choice for professional deployment.
The case for the Axiom ED120A. High-quality vendor Spinorama data gives it a 5.73 ideal-subwoofer preference score and 52Hz bass extension, a solid tonal showing for a professional cabinet. CORE DSP, PRONET remote control and an asymmetric rotatable horn add useful installation flexibility.
Important trade-offs. Its 82Hz measured bass extension and 131dB peak claim mean it depends more on a subwoofer than the strongest stand-alone boxes. Buyers who do not need networked audio may find better value in simpler mainstream models. The 132dB claimed peak is competitive rather than class-leading, and the asymmetric 60°-to-100° pattern needs more deliberate aiming than a conventional symmetric horn. Availability and service coverage are less broad than the mainstream QSC, JBL, Yamaha and RCF choices.
Buy the HK Audio LINEAR 9 112 XA when its stated format, coverage, and system features fit the job better.
Buy the Axiom ED120A 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.
