INTRODUCTION

evoke3 is, with a total installation depth of just 17 cm (6.7 inches), a highly integrable solution for any music venue that hosts a variety of music styles and events. Non-perforated panels subtly tilt when the system is ON.

The panels can have a variety of sizes and finishes and are our most discreet solution, simply offering variable acoustics building blocks with a subtle and minimalistic expression while still complying with the latest acoustic research findings, performing top-notch!

Panels can be angled in the closed state or have a curved or scattering surface to render a more sound-diffuse room.

HOW IT WORKS

When evoke3 is OFF, it’s invisible. When ON, the panels subtly tilt, absorbing sound through gaps. 

These gaps absorb significantly more sound in the 125 Hz band than higher frequency sounds in and above the 250 Hz band. And it's not a bug - it's a feature! This is due to a two times higher absorption coefficient by audience/chairs and a twice as high directivity factor of the PA system speakers in the 250 Hz octave band compared to the 125 Hz band. This effect is even more pronounced in higher frequency bands. evoke3 also has a frequency variable aspect: The greater the gap, the greater the absorption from 250 Hz and above.

We have scientifically substantiated that reverberation time benefits from rising towards higher frequencies - even when factoring in the audience and furniture. A relatively low RT value, especially at bass frequencies, is crucial for amplified music to sound great.

DESIGN

evoke3 is visually discreet by nature - subtle when ON and invisible when OFF. The front is a wooden board available in any finish - lacquered, veneered, etc. 

The panels can be made in virtually any size - the maximum is 300 x 120cm (118.1 x 47.2in), but it is possible to order even larger, custom-made evoke3  panels.

However, it is essential to know that size affects the absorption coefficient.

CONTROL

Once the modular evoke3 panels are installed, you can create presets to fit any type of music or event the room allows for, and switching between them happens in seconds in our app that you can run seamlessly on any tablet or laptop.

evoke3 can be controlled on a per-panel basis, and we help create the required presets for your needs.

This way, you can easily pre-schedule your entire season in the app, ensuring that once the artists are in for the soundcheck, the acoustics are already optimized for their performance. Plus, the sound engineer is now free to polish the fine sonic details rather than struggling to make it fit into the room in the first place.

We guarantee it will be a much better experience for all parties involved, from the artists to the engineer and not least the audience.
