HK Audio LINEAR 5 MK2 112 XA 12" Active Speaker

HK Audio LINEAR 5 MK2 112 XA

The HK Audio LINEAR 5 MK2 112 XA is the most compact 12-inch multifunctional speaker in its class, delivering 1200W peak bi-amped power through a 12-inch woofer and 1-inch compression driver. Reaching 136dB peak SPL while weighing just 38.8 pounds, this cabinet serves equally well as FOH reinforcement or high-powered stage monitoring. The FIR crossover at 1.9kHz with 72dB/octave slope provides phase-coherent driver integration across the transition frequency, while the rotatable 80° x 60° CD horn adapts coverage patterns to room geometry. Networked DSP control via EtherCON enables remote adjustment of 10-band parametric EQ, delay, limiting, and filtering—critical for dialing in system response without climbing behind stacks.

In both touring and installed applications, the 112 XA's 31-degree monitor angle and DuoTilt pole mount (3°/7° options) provide flexible positioning. The hybrid birch multiplex/MDF construction balances acoustic performance with manageable weight, while the black acrylic enamel finish survives transport abuse. Frequency response extends from 67Hz to 19kHz (-10dB), covering full-range content without requiring subwoofer support in speech-reinforcement or monitoring applications—though it integrates seamlessly with LINEAR subwoofers when deeper bass is needed. The dedicated DSP output provides processed signal for non-networked speakers, expanding system flexibility. Filter presets (Flat, Monitor, Low Cut, Remote) offer quick starting points for common deployment scenarios. At 14" x 23" x 12", the compact dimensions fit tight stage corners and small venue installations where larger cabinets become problematic. Explore our powered speakers for more compact PA solutions.

Bi-Amped Class-D Power With FIR Crossover

The 600W RMS (1200W peak) bi-amped design dedicates separate amplifier channels to the 12-inch woofer and 1-inch compression driver, optimizing power distribution across the frequency spectrum. The FIR (Finite Impulse Response) crossover at 1.9kHz uses a steep 72dB/octave slope to provide phase-coherent summation between drivers—critical for maintaining accurate frequency response through the crossover region where phase anomalies typically cause notches in the response. This results in smoother on-axis response and more predictable off-axis behavior compared to traditional IIR crossovers. Maximum SPL reaches 136dB peak with 128dB continuous output averaged across 70Hz to 12kHz, providing enough headroom for transient peaks in live music without compression or distortion. The 12-inch woofer features a 2.5-inch voice coil that handles thermal stress during sustained high-output operation, while the 1-inch compression driver with 1.7-inch voice coil maintains clarity in the high-frequency range. 

Rotatable Horn For Adaptable Coverage

The 80° x 60° CD (Constant Directivity) horn rotates to match horizontal or vertical orientation—essential when using the cabinet as a stage monitor where you need wider horizontal coverage, or as FOH reinforcement where narrower vertical dispersion prevents ceiling reflections. The horn maintains consistent coverage across its rated angles rather than exhibiting the pattern narrowing at high frequencies common with non-CD designs. This predictable dispersion simplifies system design and reduces the acoustic treatment needed to control reflections. The 31-degree monitor angle positions the horn correctly when the cabinet is floor-wedged, directing sound toward the performer's ears rather than their knees. The DuoTilt pole mount offers 3-degree or 7-degree downward tilt options for FOH applications, allowing precise aim adjustment when mounted on subwoofers or speaker stands. Three M8 rigging points (AP-8 compatible) support flying applications in permanent installations or touring rigs requiring overhead positioning.

Networked DSP Control For System Integration

EtherCON RJ45 connectivity enables remote control via DSP CONTROL software (Windows/macOS), providing access to fully parametric 10-band EQ with variable filter characteristics, high/low-pass filters, polarity control, level adjustment, delay (for time-alignment), limiting, and mute functions. The 48kHz sample rate with less than 2ms system latency maintains timing accuracy critical for live performance, while the filter presets (Flat, Monitor, Low Cut, Remote) offer optimized starting points for common applications. Flat mode provides unprocessed response for systems using external DSP, Monitor mode optimizes frequency balance for stage wedge use, and Low Cut engages high-pass filtering when pairing with subwoofers. The dedicated DSP output provides processed signal for integrating non-networked speakers into controlled systems—useful when expanding existing rigs with mixed gear. The hybrid birch multiplex/MDF cabinet construction balances acoustic performance with transport practicality, and the 38.8-pound weight makes single-person positioning manageable. Two SingleGrip handles support balanced lifting, while the black acrylic enamel finish and 2mm steel grille with acoustic foam backing protect drivers during transport and setup.
