The Vyper-KV52 l is a 50-cm-long passive line array comprised of eight 1” neodymium magnet transducers housed in an elegant and resistant aluminium chassis.

The Vyper-KV52 l features two different values of impedance (16Ω – 64Ω) with the benefit of comprising up to 16 units powered from a single 4Ω amplifier channel at the higher impedance, eliminating the need for dedicated 70 V amplifiers in wider distributed installed systems. The Vyper is able to reproduce the whole vocal frequency range with high intelligibility and unparalleled directivity.

The Vyper line is the flattest speaker in the K-array portfolio. The passive speaker system is housed in an elegant and resistant 2-cm-deep aluminium frame turned on a lathe from a solid metal block.

With closely-spaced cone drivers, the Vyper demonstrates true line array characteristics: phase coherence, low distortion and focused listening in both the near field and at a distance from the speaker. This Pure Array Technology allows the Vyper to cover venues uniformly and provide long throw.

For easier use and integration with other speakers or amplifiers, the Vypers feature selectable impedance and when paired with one of the subwoofers in the Rumble line, powered by a Kommander amplifier with specific presets optimized for the Vyper, the loudspeaker assures excellent coverage of the entire musical frequency range. A steel bracket accessory provides an option to mount wall application for permanent installations.

All Vyper components can be colour customized to match any RAL code or coated with a premium brushed or polished stainless steel finish which give the products a chameleon-like ability to reflect surrounding surfaces and blend in with the background. The most luxurious finish is our 24K gold-plated aluminium which renders exceptional performance in a variety of distinct finishes combining beauty and design.

Modular Capabilities

The length of a line array is a crucial parameter to consider when approaching the design of a sound system. The longer the distance to cover, the longer should be the array. For maximum adaptability to any venue, our slim line arrays have modular capabilities: dedicated hardware allows the joining of more units to reach the desired length and guarantee a perfect coverage of the entire audience area.

Visually Discreet

For architectural reasons, a visually discreet audio system may be required to integrate seamlessly with the layout without compromising sound quality. We put careful thought into designing a sleek form factor taking into consideration shape, space and function, resulting in a delicate balance of durable materials and advanced technology.


We created a portfolio complete with lightweight products that are easy to transportation and quick to setup optimizing logistics, space, labour costs and time. Boasting an incredible size-to-weight ratio, the most important factors of our audio solutions’ weight are design methods, materials and manufacturing technology. Our strategy consists of utilizing minimal components and certain lower-density materials like aluminium and steel.

Colour Customizable

We have the ability to customize your project by colour matching your system to any RAL colour to help you to better integrate the speakers into a wide variety of venues. RAL is used for defining standard colours for paint and coatings and is the most popular Central European colour standard used today.

Pure Array Technology

Composed of closely-spaced, full-range sound sources, our line array elements feature demonstrate pure line array characteristics.

With no drivers dedicated to the high frequencies, no bass reflex or passive radiators dedicated to the low end, there are no crossover points and a perfect phase response is achieved in both the near and far fields.

All the sound sources in the array are identical and perfectly coupled producing a true line array with benefit of having the sound beam radiated by the column very wide on the horizontal plane and very narrow on the vertical plane. The amount of energy sent towards the ceiling and the floor is then minimized greatly improving the intelligibility in highly reverberant venues like houses of worship and conference rooms.

Furthermore, such a focused sound beam is able to cover a long distance uniformly: both the audience located in front of the array and at the back of the venue will experience the same tonal balance without the need of several delay lines.

With no horns and no waveguides, PAT columns can be joined to create longer arrays. The longer the array, the narrower the sound beam and the further the distance that can be covered uniformly.

Dedicated accessories aid in connecting the columns and tilting at an angle, while dedicated stacking and suspending hardware render the installation quick and easy.

Made from stainless steel with the possibility to customize the appearance with fine finishes and an endless spectrum of colour choices, K-array’s discreet PAT columns meet the demands of architects, system integrators and rental companies alike who are looking for invisible systems that provide excellent audio quality in sleek form.

Selectable Impedance

When connecting many loudspeakers in parallel to the same amplifier output channel, impedance matching is no more an issue! Selectable impedance lets the user to choose the right loudspeaker impedance value allowing to set the proper load and maximize performance.
