HK Audio Linear 5: The Subwoofer That Makes the Difference!

The series' bass-reflex subwoofers provide the solid foundation of the new LINEAR 5 MK II systems with uncompromising power and dry, defined bass reproduction that reaches deep into the low end. Cardioid settings selectable by preset give the user a greatly expanded range for system configuration and open the door to the professional tier. Stereo preamps simplify 2.1 setups.

As the most powerful subwoofer of the LINEAR 5 MK II series, the Sub HPA delivers significantly more low-end energy than any other sub in the series thanks to its stiff, highly durable 18-inch woofer and its potent amplifier. That results in especially precise and punchy bass reproduction at very compact dimensions. It therefore not only forms the perfect foundation for the LINEAR 5 MK II 308 LTA mid/high unit, but also serves as a powerful low-end extension for LINEAR 5 MK II systems.

The high-performance DSP can be controlled remotely via network and, together with the free HK Audio DSP CONTROL software, offers extensive processing options and exact sound tuning. Cardioid presets are selectable directly on the speaker and enable 1:1 and 2:1 cardioid setups in no time. PowerCon connectors with PowerCon Link simplify cabling and reduce cable clutter.
