HK Audio LINEAR 5 MKII 115 FA - 2-way self-powered full-range system with 60° × 40° horn and DSP

HK Audio LINEAR 5 MKII 115 FA — 2-way self-powered full-range system with 60° × 40° horn and DSP

The HK Audio LINEAR 5 MKII 115 FA is a 15" + 1" self-powered full-range speaker cabinet designed for professional applications where deep bass, long-throw projection and agile setup are required. It combines a 15" woofer with a 3" voice coil and a 1" compression driver (1.7" voice coil) in a 60° × 40° rotatable horn for easy clustering and room matching. Its 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 offers direct presets and advanced tools. Thanks to DSP Out and EtherCon network control (Windows / macOS), it quickly integrates 2.1 systems, arrays with LINEAR 5 MKII subs, or as a high-performance standalone solution.

Main features

• 2-way architecture : 1 × 15" (3") + 1" (1.7") on 60° × 40° rotating horn .
• Power : 600 W RMS / 1,200 W peak (Class D bi-amplified); max SPL 138 dB peak.
• Frequency response : 57 Hz – 12 kHz (±3 dB) / 54 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, Boost, Low Cut and Remote (via software).
• Connectivity : XLR combo (In), XLR (Thru), XLR DSP Out and EtherCon RJ45 (In) for control.
• Professional workflow : 10-band parametric EQ, HPF/LPF, polarity, level, delay , limiter and mute .
• Touring construction : low-resonance birch/MDF hybrid enclosure, 2 mm grille with acoustic foam, DuoTilt 3°/7° , 3 × M8 and 2 MultiGrip handles.

Product benefits

• Projection and clarity over medium and long distances thanks to the 60° × 40° horn and FIR filtering.
• Versatility as a standalone full-range speaker or combined with LINEAR 5/LINEAR Sub subwoofers.
• Quick setup : direct presets from the panel, DSP Out for tops without DSP and centralized network control.
• Durability with birch/MDF joinery, acrylic enamel finish, and tour-ready hardware.

Use cases

• Main reinforcement in venues, clubs, mobile discos and corporate events.
• Live music apps that need greater reach and impact.
• Modular systems with subwoofers (e.g. 115 Sub A / 118 Sub A) and cluster configurations.

Connectivity and control

It features 1 × XLR combo (balanced input), 1 × XLR Thru for linking to another unit, 1 × XLR DSP Out for the DSP-processed signal, and an EtherCon RJ45 (In) for control and monitoring via HK Audio DSP CONTROL (Windows/macOS). The software allows you to adjust EQ, filters, level, polarity, delay , and limiters throughout the entire chain.

Frequently Asked Questions

• Does the RJ45 port carry digital audio? No. The RJ45 is only for DSP control ; audio is handled by the analog inputs/outputs and the DSP Out .
• Can the speaker be rotated? Yes, the 60° x 40° speaker can be rotated to facilitate clustering and adapting to the venue.
• Does it work well without a subwoofer? Yes, it offers a full-range response with excellent punch; with a subwoofer, it gains extension and headroom in the low frequencies.
