Professional wooden cabinets, high-quality components and innovative technologies make the LINEAR 5 from HK Audio the loudest speaker family in its class. The wide-range of short and long-throw solutions, active and passive models and customised controller power amps provides professional bands and sound technicians with an exceptionally high-quality, flexible and economical solution for everyday use – all made in Germany.
The ultimate live performance system
When it comes to delivering truly powerful performances, the LINEAR 5 series components prove to be absolute powerhouses. Designed to handle daily use masterfully, they are the most powerful speaker series in their class, both in the passive and active versions. The robust LINEAR 5 system family, designed in traditional wooden construction, guarantees long-lasting use, making it the tour companion of choice for professional bands, DJs and rental services. It frees up space in the truck and, even more importantly, in the budget. The LINEAR 5’s perfectly matched mid-range driver/tweeter and three fundamentally different subwoofers make it the perfect bespoke solution for events with up to 3,000 people and more.


Excellent long and short throw performance
Whether for powerful, high-volume music transmission, high-fidelity speech reproduction or background sound – the finely tuned LINEAR 5 set configurations live up to the high demands that a durable, high-quality PA system has to meet. HK Audio’s specially developed Multicell Transformer (MCT) technology in the long-throw version manages to achieve what is normally only possible with larger horns or line arrays: distortion-free transmission at a high effective level. A real all-rounder, LINEAR 5 also boasts simple and intuitive handling.
LINEAR 5 112 F

12″/1″ full-range mid/high unit with the strongest bass range in its class and asymmetrical horn ( 60º – 90º x 55º ) for optimised sound distribution. The switchable EQ means it can be used in stand-alone applications or in a stereo pair, as well as a system mid/high unit in conjunction with a LINEAR SUB subwoofer.
LINEAR 5 112 FA

The active 12″/1″ full-range mid/high unit is incredibly powerful with its 1,000 watts of power. The switchable frequency adjustment means the full-range speaker for small to medium-sized rooms can be transformed into a powerful mid/high unit for LINEAR basses in no time at all.
The asymmetrical, rotatable constant directivity horn (60° – 90° x 55°) ensures a wide sound distribution at close range as well as broad coverage.
Whether standalone or in combination with the basses in the LINEAR SUB series, the LINEAR 5 112 FA is a flexible, extremely powerful and thus economical speaker for bands, DJs, schools and clubs.
LINEAR 5 112 X

12″/1″ model in a multifunctional housing with exceptional maximum sound pressure (135dB max. SPL peak) in combination with the Linear Sub 2000 for system applications. The LINEAR 5 112 X is also ideally suited as a monitor with plenty of gain before feedback; the rotatable 60° x 40° CD horn produces exemplary dispersion.
LINEAR 5 112 XA

The LINEAR 5 112 XA is an active multifunctional speaker optimized for voice reproduction in the frequency range from 100 Hz upwards and therefore ideal for use as an active mid/high unit for high ranges.
Since these applications do not require a high level of deep bass, HK Audio has cut down on cabinet volume in the design and developed a clever, compact multifunctional cabinet: Thanks to the slanted cabinet shape and the 60° x 40° CD horn for optimized, directional dispersion, the speaker also acts as an amazingly powerful stage monitor with low feedback.
The professional standards are rounded off by the wooden cabinet, high-quality components and innovative technologies that make the LINEAR 5 from HK Audio the loudest speaker family in its class. The LINEAR 5 112 XA also proudly bears the label “Made in Germany”.
LINEAR 5 115 F

As a stand-alone speaker with a maximum power handling capacity of 2,400 watts peak, the 15″/1″ full-range mid/high unit is the loudest reference in its class. Like the LINEAR 5 112 F, it is equipped with an asymmetrical horn for optimum dispersion, allowing it to provide a wide dispersion at the front while directing the sound more focussed in the back for a greater range. Application: Mid/high unit, standalone system, DJ monitoring
LINEAR 5 115 FA

As a stand-alone speaker with 1,000 watts of amp power, the 15″/1″ full-range mid/high unit is the loudest reference in its class due to its high efficiency. Like the LINEAR 5 112 FA, it is equipped with an asymmetrical horn for optimum dispersion, allowing it to provide a wide dispersion at the front while directing the sound more strongly in the back for a greater range.
With a sound pressure of 137 dB and the high cabinet volume, it is the most powerful speaker in its class and also delivers excellent sound characteristics.
Suitable for DJs, bands, weddings or group celebrations – there is no challenge that the LINEAR 5 115 FA cannot meet.
LINEAR 5 LTS

In the past, only large line arrays have been capable of projecting the entire frequency spectrum powerfully over 30 m and beyond – until now. For the first time, the LINEAR 5 LTS brings true long-throw characteristics to an ultra-compact format. For you as the user, this means that you’ll need fewer speaker components, thus saving valuable truck space. It also makes rigging and ground stacking much easier and faster. This makes the new LINEAR 5 Long-Throw-System LTS not only the simplest, but also the most economical solution to achieve the best sound results for small to medium-sized live and corporate events as well as installation projects.
LINEAR 5 LTS A

In the past, only large line arrays have been capable of projecting the entire frequency spectrum powerfully over 30 m and beyond – until now. The LINEAR 5 LTS A brings true long-throw characteristics to an ultra-compact format. For the user, this means fewer speaker components are required, thus saving valuable truck space. It also makes rigging and ground stacking much easier and faster. This makes the LINEAR 5 LTS A Long-Throw System not only the simplest, but also the most economical solution to achieve the best sound results for events with up to 3,000 people.
LONG THROW
Whether it’s 30, 40 or 50 metres – the LINEAR 5 LTS A projects even sophisticated high-frequency signals to the very last row. This is made possible by the innovative Multicell Transformer (MCT), a completely new technology developed by HK Audio. This development achieves a drastic reduction of the distortion in the high-frequency range. This solves a key problem posed by previous horn and wave guide designs: the limitation of the usable sound pressure due to distortion. The LINEAR 5 LTS A is thus able to generate an exceptionally high maximum sound pressure level of 138 dB. In combination with the curved array effect created by the arrangement of the Multicells, this results in a marked range extension with precise coverage of the sound field with crystal-clear audio.
ULTRA-COMPACT
The Multicell Transformer technology makes it possible to design particularly compact speaker systems with outstanding handling characteristics. This new generation of the LINEAR 5 series is ultra-compact and lightweight with dimensions of 68 x 44 x 46 cm and a weight of just 24.9 kg. Yet it can easily replace speaker systems that are twice as large and much heavier: this means less truck space is taken up and rig installation is simplified. The classic, straightforward format of the LINEAR 5 LTS A makes ground stacking intuitive and straightforward. What’s more, practical head stacking and clustering capabilities make the LINEAR 5 LTS A the most flexible product in its sound class.
ECONOMICAL
Advanced features, low investment costs, low transport volume and short assembly times. The LINEAR 5 LTS A allows you to save in three ways: staff, truck space and time. This increases your flexibility when planning within given production budgets and makes it the most economical solution in this segment.
LINEAR SUBS are system subwoofers that work perfectly with the LINEAR 3 and LINEAR 5 mid/high units.
The system subwoofers all have a stereo input, so in addition to half-stack or full-stack applications, they can also be used as a 2.1 system or mono-summing sub-cluster.
We recommend the following combinations to achieve the ideal ratio between the mid/high unit and the subwoofer:
LINEAR SUB 1500 A and LINEAR SUB 1800 A with the LINEAR 3 mid/high units,
LINEAR SUB 1200 A and LINEAR SUB 2000 A with the LINEAR 5 mid/high units and
LINEAR SUB 4000 A with the LINEAR 5 LTS A powerhouse.
LINEAR SUB 1200 / 1200 A

The LINEAR SUB 1200 / 1200 A was developed to complement the LINEAR 5 112 F/FA. The two 10″ chassis in the bass-reflex cabinet deliver extremely high impulse fidelity and a dry bass foundation that packs a lot of punch. The 10″ chassis not only provide plenty of power, they also allow for an exceptionally compact design in the LINEAR 5 112 F/FA format. The active LINEAR SUB 1200 A uses the same 1,200-watt digital power amp as the LINEAR SUB 2000 A and releases its excess power via a Speakon out, to which a passive LINEAR SUB 1200 can be connected. This allows you to expand your system very effectively into a slim and lightweight yet extremely powerful full stack.
LINEAR SUB 2000 / 2000 A

The LINEAR SUB 2000 / 2000 A is the perfect companion to the LINEAR 5 115 F/FA. It features two 12″ long-excursion chassis in a bandpass cabinet, which boast impulsive dynamics and an impressive low-frequency response below 40 Hertz. It performs well not just at peak impulses, but also at continuous power! To this end, the chassis are equipped with a dual damper that guarantees exact centring of the voice coil even under the most extreme loads. Advanced cooling technology effectively prevents the voice coil from overheating. The active LINEAR SUB 2000 A is powered by a 1,200-watt digital power amp, which weighs just two kilograms more than the passive subwoofer.
LINEAR SUB 4000 / 4000 A

The LINEAR SUB 4000 / 4000 A is the flexible 18″ subwoofer from HK Audio. It is compatible with all LINEAR 5 full-range speakers and mid/high units and delivers an impressively powerful low-frequency response from 30 to 100 Hertz. The new LINEAR SUB 4000 / 4000 A can be used as a sub-low extension to the existing LINEAR SUB 2000 (A), delivering powerful low bass in the range of 30 to 70 Hertz.
The two other active LINEAR SUB subwoofers can also be combined with the LINEAR 5 active mid/high units.
LINEAR SUB 1500 A

SYSTEM SUGGESTIONS PASSIVE
For more than 20 years, HK Audio has been a pioneer in the field of active sound reinforcement components, or in other words, speakers with built-in power amps and controller electronics. Integrated systems like these are often easier to transport, assemble and operate. However, there are still many applications, especially in the rental and installation sector, where a central power amp rack combined with passive speakers is the more practical or economical solution.
Based on the latest generation of advanced controller amps from market leader Lab.Gruppen, our application specialists have developed a concept for unified power racks where one amp rack can drive a variety of different HK Audio speaker setups with precision – all you need to do is activate the appropriate filter set.
A complete library of filter sets is already stored in the power amps’ memories. For professional users, a unified amp rack is the key to making configuration, handling, and operation simpler and flexible enough for use in smaller and larger systems, as well as simplifying service and maximising the lifespan. That’s why we call it the Key Rack. Easy to handle, highly efficient and cost-effective, with elegant remote control via iPad or PC, too.

KEY RACK 2.24
The Key Rack 2.24 is a lightweight, compact rack that is three units high. It is equipped with the new, groundbreaking IPD 2400 controller amps (2 x 1,200 W @ 4Ω) made by Swedish specialists Lab.gruppen.
The two IPD 2400s, the integrated power distribution and the preloaded LoadLibrary (preset settings) form the turnkey, highly efficient drive for the LINEAR 5 LTS system. As a result, the Key Rack can be used universally right off the bat. This makes professional applications with HK Audio systems of various kinds a piece of cake, while maximising the equipment’s operational reliability. At the same time, this simple and highly efficient system can be controlled remotely via PC or iPad.
