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.

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.
