Housed in tried-and-true wood enclosures, the rugged LINEAR 5 line is sure to deliver the goods for many tomorrows to come. What’s more, it conserves space in your truck and keeps money in your pocket.

LINEAR 5 puts hardworking bands, mobile DJs and rental companies on the most economical and convenient path to awesome audio. Roaring riffs, big beats, crisply clear speech, background music—the LINEAR 5 sets are configured and fine-tuned to deliver everything the professional expects in a resilient, high-quality PA system. Long throw versions feature HK Audio’s proprietary Multicell Transformer (MCT) technology. Its ability to deliver distortion-free signals at high effective sound pressure levels rivals that of very big horns and line arrays. And seasoned road warriors will certainly to appreciate the multifunctional LINEAR 5 speakers’ simple, intuitive handling.

With its perfectly matched midrange/HF speakers and three fundamentally different subwoofers, LINEAR 5 is tailor-made for events with audiences of 3,000 people and more.

LINEAR 5 112 X/XA

Fine-tuned for rendering speech in the key frequency range starting at 100 hertz, the L5 112 X / XA is predestined for use as a mid/ high unit to cover great throw distances. Such applications do not require a tremendous amount of low-end reinforcement, so HK Audio opted for an ingenious space-saving housing that is angled, surprisingly compact, and equipped with a 60° x 40° CD horn for optimum directivity.
Able to handle plenty of gain before feedback, this multifunctional enclosure can even serve as a powerful stage monitor.

LINEAR 5 112 F/FA LINEAR 5 115 F/FA

These are two extraordinarily versatile fullrange models.
Just two L5 112 F / FA units mounted on speaker stands can provide genuine fullrange coverage. The L5 115 F / FA delivers rich, low-ranging bass response to satisfy that will satisfy even the challenging monitoring demands of discerning DJs. Both models feature an asymmetrical, rotatable constant directivity horn (60° – 90° x 55°) that provides wide-ranging coverage in the near field, paired with plenty of long-distance reach. Variable EQ presets let you adapt the frequency response: A flip of a switch is all it takes to transform these fullrange speakers for small to midsized rooms into powerful top units for LINEAR subwoofers.

Features

All models are equipped with two class D amplifiers, one each for the tweeter and woofer. The integrated controller provides three active protective circuits (short circuit, thermal, over/under voltage), a peaklimiter and a subsonic filter to maximize both load handling and component life.

LINEAR 5 LTS/ LTS A

Long Throw. Ultra Compact. Economical.

What does it take to throw the entire frequency spectrum over 30 meters and beyond? Only large line arrays pack a punch powerful enough to deliver that kind of performance. Until now, that is.

LINEAR 5 LTS / LTS A has arrived, and it’s the first speaker to deliver real long throw performance in an ultracompact format. Now you can hit the road with fewer speaker components in tow, saving valuable space on your truck. What’s more, you can set up, stack and fly rigs that much faster and easier.

The new LINEAR 5 LTS / LTS A is not only the easiest way of treating audiences of up to 3,000 to the best sound; it’s also the most economical option out there.

Long Throw

Whether it’s 30, 40 or 50 meters – the new LTS / LTS A mid/high unit throws the sonic image as far as it needs to go, sending even silky top-end frequencies all the way to the back row. This is made possible thanks to HK Audio’s groundbreaking Multicell Transformer technology. This ingenious invention drastically reduces high frequency distortion, thereby solving a major problem of legacy horn and waveguide designs: they generate distortion that limits the amount of useful sound pressure.
Equipped with this proprietary technology, the LTS / LTS A is able to deliver 138 dB SPL, an exceptionally high maximum by any standard.
This awesome power, paired with a curved array created by the multiple cells, extends the range to cover the entire sound field with a crystal-clear audio image.

Ultra Compact

The pioneering Multicell Transformer makes setting up compact speaker systems an exercise in convenience. The latest generation LINEAR 5 series model is housed in an ultra-compact 68 x 44 x 46 cm enclosure. Tipping the scales at just 24.9 kg, LTS / LTS A can easily replace speakers twice its size and weight to save truck space and make installation in a rig so much easier. LTS / LTS A’s classic streamlined format is certainly a refreshing change. Talk about intuitive handling: finally, here’s a straightforward design that can be stacked on the ground or on its head, and clustered with remarkable ease and flexibility. All this contributes to making LTS / LTS A easily the most flexible tool in its class.

Economical

Sophisticated features, a remarkably affordable price, a small footprint and fast setup. With the LINEAR 5 LTS / LTS A, your savings are threefold: peoplepower, truck space and time. This gives you far greater leeway for planning the given production’s budget, as well as making the LTS / LTS A the most economical solution in its application range.

To date, there have been two ways to construct long range speaker systems. The time-tested approach is to use long throw horns. They have to have very large mouths and deep enclosures to accommodate the horn’s throat, so the housings are huge. Plus, there’s a lot of real estate inside the horn. These surfaces cause resonances and reflections that manifest as distortion, particularly at high frequencies. This distortion puts a very low cap on the maximum achievable sound pressure.

The other option for long throw applications, the line array, has been around for about 20 years. Waveguides shape the wave-front so that the line array is able to render even high frequencies well. The downside is that you have to haul, assemble and align a whole lot of speakers even for small or medium-scale events, which costs you truck space, time and money.

HK Audio engineers took up the challenge of reinventing the long throw speaker and came up with a ground-breaking solution: the Multicell Transformer (MCT). This ingenious invention makes the most of horns’ and waveguides’ physical advantages, with none of the drawbacks. The mouths of the nine horn channels form a line array, with sound traveling down channels of different lengths to achieve different delay times. This yields a perfect vertical curve and a very precise +5°/-25° pattern of throw.
With these unique properties, the MCT achieves the performance of comparable horns and waveguides at a fraction of their size. This revolutionary advance in technology is the key to building sensationally small and streamlined speakers.
Here’s a simplified run-down of how it works: the MCT splits the wave-front into nine small wave-fronts. Each of these partial waves is directed through the flaring duct of a horn of different length and mouth size. These horns don’t have acres of real estate that can cause interference, so the only distortion they generate is beyond the range of human hearing. This increases useful sound pressure by up to 10 dB.

SUGGESTED SYSTEM SETUPS: PASSIVE

HK Audio has spearheaded the drive to advance the state of the art in active sound reinforcement – that is, speakers with built-in power amps and controllers – for more than 20 years. Such integrated systems are often easier to transport, set up and operate. However, there are many applications, particularly for rental and installed systems, where a central power amp rack paired with passive speakers is the more practical or affordable solution. Our application specialists have developed a concept for unified power racks featuring the latest generation of advanced controller amps made by market leaders Lab.gruppen. These amp racks can be easily configured to drive a variety of HK Audio speaker setups simply by selecting the appropriate filter set. A complete library of filter sets is already archived in the power amps’ memories.
