HK Audio LINEAR 5 MKII 112 XA — 2-way self-powered full-range system with 80° × 60° speaker and DSP

The HK Audio LINEAR 5 MKII 112 XA is a 12" + 1" active PA speaker designed for professional applications requiring vocal clarity , controlled throw and rapid deployment. Its multi-function enclosure with 31° monitor wedge and 80° × 60° rotatable horn allow it to be used vertically or horizontally, as a stand-alone full-range speaker , top -over-subwoofer or stage monitor . It features a 600W RMS / 1,200W peak bi-amplified Class D amplifier and high-performance 48kHz DSP with FIR filter , direct presets and EtherCon network control (Windows/macOS). With a max SPL of 136 dB peak and low-resonance birch/MDF hybrid construction, the 112 XA delivers transparent, punchy sound on the road, in clubs and in fixed installations.

Main features

• 2-way architecture: LF 1 × 12" (2.5" coil) + HF 1" (1.7" coil).
• Power and sound pressure: 600 W RMS / 1,200 W peak (Class D, bi-amplified); 136 dB peak .
• Constant directivity horn: 80° × 60° , rotatable , to optimize vertical or horizontal coverage.
• Frequency response: 73 Hz – 12 kHz (±3 dB) / 67 Hz – 19 kHz (–10 dB).
• FIR Crossover: 1.9 kHz with 72 dB/oct slope for precise transitions.
• Professional DSP: 10-band parametric EQ, HPF/LPF, polarity, level, delay , limiter, and mute ; latency < 2 ms.
• Direct presets: Flat, Monitor, Low Cut and Remote.
• Connectivity: 1 × XLR/TRS combo (balanced input), 1 × XLR Thru, 1 × XLR DSP Out (processed signal), 1 × EtherCon RJ45 (In) for control.
• Touring-grade joinery: birch/MDF hybrid enclosure, DuoTilt 3°/7° , 3 × M8 points, 2 SingleGrip handles, 2 mm metal grille with acoustic foam.
• Safe power supply: IEC cable with lockable V-Lock .

Product benefits

• Projection and intelligibility: Tightly controlled coverage (80° × 60°) maintains clarity at medium distance and reduces unwanted reflections.
• True versatility: works as a full-range top, 31° stage monitor or combined with LINEAR 5 MKII subwoofers (115/118).
• Agile configuration: presets from the panel, DSP Out to link boxes without a network, and centralized control via EtherCon.
• Robustness and reliability: low-resonance hybrid cabinet with protected electronics for intensive rental and touring use.

Use cases

• Main reinforcement in rooms, clubs and corporate events.
• Stage monitor for vocals, guitar and keyboards ( Monitor preset).
• Modular systems in headstack on subwoofers or in pairs with Low Cut .

Frequently Asked Questions

• Does the RJ45 port transmit digital audio? No. The EtherCon RJ45 is used for DSP control ; audio is handled via XLR/TRS In / Thru and DSP Out .
• Can the speaker be rotated? Yes, the 80° x 60° angle can be rotated to fine-tune coverage or create a cluster.
• What is the maximum input gain? Up to +20 dBu (maximum input level).
