PASSIVE

LINEAR 5 LTS

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.

The LINEAR 5 LTS passive speaker has arrived, and it’s the ﬁrst speaker to deliver real long throw performance in an ultra-compact 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 passive is not only the easiest way of treating small to midsize Live-, and corporate events as well as installation projects 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 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 ground-breaking 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 is able to deliver 138dB 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 46cm enclosure. Tipping the scales at just 26.4kg, the LTS can easily replace speakers twice its size and weight to save truck space and make installation in a rig so much easier. The LTS’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 the LTS easily the most ﬂexible tool in its class.

ECONOMICAL.

Sophisticated features, a remarkably aordable price, a small footprint and fast setup. With the LINEAR 5 LTS, 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 the most economical solution in its application range.

THE INNOVATIVE MULTICELL TRANSFORMER

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 dierent lengths to achieve dierent 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 dierent 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 10dB.

Thanks to the MC T horn’s asymmetrical directiv ity, two LINEA R 5 LTS units can be set up together in an ”acoustically correct” head stack.

LINEAR SUB 4000

Powerful and Versatile

L SUB 4000 is the ﬂexible new 18" passive subwoofer from HK Audio. Compatible with all LINEAR 5 fullrange speakers and mid/high units, its powerful low end — ranging from 30 to 100 Hertz — is totally and powerfully impressive. L SUB 4000 can also serve as a sub-low add-on to LINEAR SUB 2000 to beef up the bottom end in the range of 30 to 80 Hertz.

Innovative and Combinable

The chambers of this double-ventilated band-pass enclosure were tuned dierently, and optimized for ultra-low signals and kick drums. L SUB 4000 can be deployed ﬂexibly as the sole subwoofer for a PA or as a sub-low extension unit.

HK Audio engineers tuned the L SUB 4000’s band-pass enclosure and the ﬁlter presets to deliver phase-corrected response when paired with the L SUB 2000. This means the L SUB 4000 can be added to a legacy system without requiring additional outboard controllers. To this end, the freely assignable terminals, which are switchable between the ﬁrst and second pair of NL4 connectors, give you even more cabling options.

Dynamic and Faithful Response

Rugged high-tech courtesy of German engineering: HK Audio has decades of experience developing advanced sound reinforcement solutions, and the L SUB 4000 has also beneﬁtted from our engineers’ unique skillset. This subwoofer delivers high maximum SPL paired with dynamic, deep-ranging response, and renders signal peaks with remarkable ﬁdelity even when pushed very hard. Its robust wood housing is built to withstand the wear and tear of daily use.

L SUB 4000 is perfectly suited for professional gigs and installation in clubs. Presets that include the correct limiter thresholds for the system controllers / ampliﬁers protect electronic components from overloads to ensure this unit will keep delivering reliable performance for many, many tomorrows to come.
