HK Audio LINEAR 5 MKII 115 XA — 2-way self-powered full-range system with 70° × 50° speaker and DSP

The HK Audio LINEAR 5 MKII 115 XA is a 15" + 1" active full-range speaker designed for professional main reinforcement, live music installations, DJ sets, and stage monitor applications. Its multi-angle 31° wedge design and 70° × 50° rotatable horn provide controlled projection and versatility in either vertical or horizontal operation. The bi-amplified Class D amplifier delivers 600 W RMS / 1,200 W peak reaching up to 138 dB peak , while the 48 kHz DSP with FIR filter ensures a smooth transition to 1.6 kHz and features direct presets for quick commissioning. With DSP Out and EtherCon network control (Windows/macOS), it easily integrates 2.1 systems and LINEAR 5/LINEAR Sub subwoofer combinations.

Main features

• 2-way architecture: 15" woofer (3" coil) + 1" compression driver (1.7" coil) in 70° × 50° rotating horn (CD).
• Power and SPL: 600 W RMS / 1,200 W peak (Class D bi-amplified); max SPL 138 dB peak / 130 dB average (half-space).
• Frequency response: 64 Hz – 12 kHz (±3 dB) / 59 Hz – 19 kHz (–10 dB).
• Digital processing: FIR X-over at 1.6 kHz (72 dB/oct), 48 kHz sampling, latency < 2 ms.
• Built-in presets: Flat, Monitor, Low Cut and Remote (via software).
• Connectivity: 1 × XLR/TRS combo (In), 1 × XLR (Thru), 1 × XLR DSP Out and EtherCon RJ45 (In) for control.
• DSP Tools: 10-band parametric EQ, HPF/LPF, polarity, level, delay , limiter and mute .
• Touring-grade construction: low-resonance (bass-reflex) birch/MDF hybrid enclosure, 2 mm grille with acoustic foam, DuoTilt 3°/7° , 3 × M8, 2 MultiGrip + 1 handle , IEC cable with V-Lock .
• Multi-function design: portrait or landscape orientation; 31° monitor wedge .

Product benefits

• Projection and intelligibility: The 70° × 50° horn maintains clarity at medium and long distances and reduces unwanted reflections.
• True versatility: works as a stand-alone full-range speaker or combined with LINEAR 5 MKII subwoofers (115/118) in a headstack or stack.
• Agile setup: direct presets, DSP Out for network-free tops, and EtherCon control for fine-tuning and monitoring.
• Reliability on tour: robust carpentry, professional hardware, and electronics with limit switches for intensive use.

Use cases

• FOH in venues, clubs and corporate events.
• Stage monitor (31° wedge) for vocals and instruments.
• Modular systems with subwoofers and cluster configurations.

Frequently Asked Questions

• Does the RJ45 carry digital audio? No. EtherCon RJ45 is for DSP control only; analog audio is provided via XLR/TRS In/Thru and DSP Out .
• Can the speaker be rotated? Yes, the 70° × 50° angle can be rotated to optimize coverage or create a cluster.
• Can it be used as a monitor wedge? Yes, the enclosure includes a 31° angle and specific presets (Monitor).
