The New Generation of the LINEAR 5 Series

Designed and manufactured in Germany, the LINEAR 5 MKII series reimagines a mobile sound reinforcement reference. This major evolution brings advanced digital control, full network management, and a more compact footprint than the previous generation, without compromising the acoustic pressure or reliability that have made HK Audio renowned. The L5MKII-118SUB-A fits at the core of the range as a versatile subwoofer for simple setups or more ambitious systems.

Who Is It For and What Are Its Uses?

Ideal for service providers, bands, DJs, clubs, and multipurpose venues, this subwoofer delivers solid bass reinforcement for live shows, DJ sets, or fixed installations. Its power reserve and presets simplify room adaptation, while networking speeds up setup, monitoring, and scene recall during tours and repetitive performances.

Performance and Advanced Control

The L5MKII-118SUB-A features a 10-band DSP with delay, polarity, low-pass filter, limiter, and mute, remotely controllable via an Ethernet connection. This allows you to create coherent systems, including combining speakers without DSP thanks to the XLR DSP output. Presets dedicated to cardioid mode facilitate reducing bass feedback on stage and improve mix clarity. Its 1,000 W RMS (2,000 W peak) power and 18-inch driver deliver a firm foundation down to the lowest frequencies, while the M20 inserts allow mounting poles for satellites and building compact, efficient stacks.
