HK Audio LINEAR 5 MKII 115 FA Powerful Full Range Active PA Speaker

The HK Audio LINEAR 5 MKII 115 FA is a powerful active full-range PA loudspeaker designed to deliver serious low-end authority and impressive projection from a single cabinet. With its 15 inch woofer, long-throw horn and finely tuned presets, it is equally at home as a standalone full-range box or as the mid/high heart of a larger LINEAR 5 MKII system.

Combining a transparent, detailed top end with the most muscular bass response in the LINEAR 5 MKII FA family, this cabinet is built for modern live sound. Whether you are running a compact stereo rig for a band or DJ, or expanding into a more complex clustered system with dedicated subwoofers, the 115 FA gives you the headroom, clarity and flexibility to scale up quickly while keeping control simple.

A rotatable constant-directivity horn and carefully controlled 60 x 40 degree dispersion make it easy to focus your sound where it is needed, while maintaining intelligibility and punch over long distances. With its dedicated preset for pairing with LINEAR 5 MKII subwoofers, you can switch from full-range mode to system mid/high duty in seconds, optimising crossover and phase without extra processing.

Robust construction, bass reflex design and compatibility with optional tilt brackets via the integrated MultiGrips mean the LINEAR 5 MKII 115 FA is ready for demanding touring, rental and installation work where reliability and consistent performance are essential.

Powerful Full-Range Performance

As an active 2-way loudspeaker with a 15 inch woofer and 1 inch compression driver, the LINEAR 5 MKII 115 FA delivers a wide frequency range from 57 Hz to 18 kHz at -6 dB, with a maximum peak SPL of 138 dB. This gives you enough output and bandwidth to run it as a true full-range box in many situations, keeping your rig compact while still providing solid low end and clear mids and highs.

Extended Throw and Focused Coverage

The longer horn design and constant-directivity 60 x 40 degree dispersion help the 115 FA project sound cleanly over greater distances while maintaining even coverage. The horn is rotatable, so you can adapt the dispersion for horizontal or vertical use, making it easier to tailor the coverage pattern for different rooms, stage layouts and cluster configurations.

Optimised for LINEAR 5 MKII Systems

A dedicated filter preset, tailored to the characteristics of LINEAR 5 MKII subwoofers, allows the 115 FA to operate as a high-output system mid/high unit with minimal setup time. Switch presets and you have an instantly optimised crossover relationship with compatible subs, improving headroom, coherence and overall system balance without needing external processing.

Flexible Rigging and Clustering

The dispersion characteristics of the horn make both horizontal and vertical clustering straightforward, helping you build larger arrays when required. With optional TB-45N or TB-45NQ tilt brackets mounted to the integrated MultiGrips, the cabinet can be rigged safely and angled precisely, giving you practical options for flown systems, installs or ground-stacked setups.

• High-Output Active 2-Way Design - The active 2-way configuration with dedicated amplification and crossover delivers up to 138 dB peak SPL, providing ample headroom for demanding live sound applications while maintaining clarity and control across the full frequency range.
• 15 Inch Woofer with Strong Bass Response - A 15 inch cone driver with a 3 inch voice coil in a bass reflex cabinet extends usable low end down to 57 Hz at -6 dB, giving the 115 FA the most powerful bass response in the LINEAR 5 MKII FA range and making it ideal for full-range use as a stereo pair.
• Rotatable 60 x 40 Degree Horn - The constant-directivity horn offers a controlled 60 x 40 degree dispersion pattern that can be rotated to suit horizontal or vertical orientation. This helps you keep coverage even and focused, improving intelligibility and reducing unwanted spill.
• Preset Integration with LINEAR 5 MKII Subwoofers - A selectable filter preset, matched to LINEAR 5 MKII subs, lets you quickly configure the 115 FA as a system mid/high cabinet. This simplifies setup, enhances system coherence and maximises usable output when building larger PA systems.
