HK Audio LINEAR 5 MKII 308 LTA - 2-way self-powered full-range speaker

HK Audio LINEAR 5 MKII 308 LTA — 2-way active long-throw speaker with MCT and DSP

The HK Audio LINEAR 5 MKII 308 LTA is a compact, modular, self-powered full-range loudspeaker designed to cover large and long rooms and outdoor events with long throws. Its Multicellular Transformer (MCT) waveguide focuses energy into a tight, controlled pattern, maintaining transparent, balanced, and powerful sound with no treble roll-off. With 3x8" drivers for low/midrange and 1" of high-frequency compression , 600W RMS / 1,200W peak Class D amplification, and high-performance DSP with FIR filter , it offers the flexibility demanded by modern live performance: ground stack, headstack , cluster, or flown . Control is via the loudspeaker itself using built-in presets or via software via EtherCon , and its DSP Out connectivity simplifies the integration of DSP-free speakers or combinations with the LINEAR family.

Main features

• Frequency response: 105 Hz – 17 kHz (±3 dB) / 98 Hz – 19 kHz (–10 dB).
• MCT horn directivity: 60° × 30° (vertical tilt +5/–25°).
• DSP with FIR and presets: Single, Cluster, Headstack, Remote selectable on the panel.
• DSP Functions: 10-band parametric EQ (variable characteristics), HP/LP filters, polarity, level, delay , limiter and mute .
• Network control: HK Audio DSP CONTROL software (Mac/Windows) via EtherCon RJ45 In/Thru ; 48 kHz sampling, latency ≤ 2.9 ms.
• Audio Connections: 1 × XLR combo (balanced input), 1 × XLR Thru , 1 × XLR DSP Out .
• Power supply: PowerCon In/Link (100–240 V), nominal consumption 1 A.
• Mounting and rigging: MonoTilt 0° pole flange, 5 × M8, 2 MultiGrip handles.
• Construction: Birch plywood enclosure, 2mm steel grille with acoustic foam; durable black finish.
• Weather protection included: RCS – Rain Cover Set to protect electronics during rain.
• Dimensions and weight: 44 × 68 × 46 cm; 25 kg.

Product benefits

• True Long Distance Coverage: MCT maintains clarity and pressure throughout the venue, reducing the need for delays .
• Hassle-free scalability: Dedicated presets for single , cluster, and headstack use with consistent results.
• Professional workflow: PowerCon Link for power chaining, DSP Out for satellites without DSP, and full network control.
• Touring-grade construction: birch wood, robust hardware and handles, designed for intensive use.

Use cases

• Theaters, auditoriums, churches, and “deep” rooms where controlled projection is required.
• Outdoor events, long-range frontfills and subwoofer headstack solutions.
• Rental companies that need a modular, powerful, and easy-to-scalable system.

Frequently Asked Questions

• Can I combine it with the 118 Sub HPA? Yes, there's full compatibility and system presets; this is common in headstacks and clusters with the 118 Sub HPA .
• Do I need software to use it? No. Presets are selected from the panel. The DSP CONTROL software allows for fine-tuning via network.
• Does it include rain cover? Yes, it comes with the Rain Cover Set (RCS) to protect the electronics while keeping connections and controls accessible.
