HK Audio Linear 5 MKII 118 Sub HPA - 3000W 18-inch Powered Bass Reflex Subwoofer with DSP Control and 4-inch Voice Coil in Black Finish

The HK Audio Linear 5 MKII 118 Sub HPA is the most powerful subwoofer in the LINEAR 5 MKII series, designed to deliver intense, precise bass reproduction while maintaining an incredibly compact form factor. Equipped with a rigid 18-inch woofer and a robust 4-inch voice coil, the Sub HPA offers exceptional low-end performance, producing deep, defined bass frequencies that add powerful extension to any audio system. With a peak power output of 3000W and an RMS output of 1500W, this subwoofer is capable of reaching a maximum SPL of 131 dB at 10% THD, making it suitable for large events and sound reinforcement applications where powerful bass is crucial. Its compact dimensions ensure it can be used in venues with limited space while still delivering the powerful performance needed for professional sound reinforcement.

The advanced high-performance DSP integrated into the Sub HPA allows for remote control and precise sound tuning via the free HK Audio DSP CONTROL software, which is compatible with both Windows and macOS. The DSP functions include a fully parametric 10-band EQ with variable filter characteristics, low-pass filters, polarity control, level adjustments, delay, limiter, and mute functions, giving sound engineers complete control over the subwoofer's performance. The speaker also includes built-in cardioid presets, such as Cardioid 1:1 vertical and Cardioid 2:1 vertical, which can be easily selected directly on the subwoofer, allowing for fast and effective setup of cardioid configurations without the need for complex measurement equipment.

In addition to its flexibility and remote control capabilities, the Linear 5 MKII 118 Sub HPA features SMART CONNECTION ports, including PowerCon for power input and EtherCon for network connection, both with link capabilities for simplified cabling and reduced material requirements. This makes it easier to create a professional sound system setup with fewer cables. The subwoofer is housed in a durable, moisture-resistant birch multiplex cabinet that ensures long-lasting performance in a variety of environments. The black acrylic enamel finish gives the subwoofer a sleek, professional appearance, while the 2 mm metal grille, backed with black acoustic foam, provides protection to the internal components while maintaining optimal sound clarity.

The Linear 5 MKII 118 Sub HPA includes four HK Audio MultiGrip carrying handles for easy transportation, making it convenient to move and set up for any event. The subwoofer also features an M20 pole mount, allowing for easy integration into a complete sound system. Designed for reliability and robust performance, this subwoofer is the ideal low-end extension for the LINEAR 5 MKII series or any other professional sound system requiring powerful bass reproduction with compact dimensions and advanced DSP control.
