Acoustic panels enable acoustic arrangement and noise reduction in rooms by means of sound absorption. Simple installation in corners enables us to make the room an ear-friendly environment. They can be mounted in control rooms, recording studios, loud rooms, radio studios, lecture rooms, halls, classrooms and other types of rooms. Having a nice outward appearance and installation options, the panel will ensure a pleasant atmosphere and add some colour to the room.

Panels are made of various materials, such as absorbent substances, acoustic fabrics, various felts and colour coated perforated steel frame, providing the panel with a rough appearance, at the same time integrating various materials together and making installation simple.

All Crux Acoustics products are entirely made in Slovenia from materials provided by Slovenian suppliers.

Crux Acoustics AP3 and AP4 acoustic panels are common versions with standard front dimensions and filled back sections, as well as enhanced perforation for increased sound absorption.

This panel helps alleviate sound anomalies occurring in corners, where the lowest frequencies usually emerge and accumulate.


The main board being of triangle shape, the backside is additionally filled with sound absorption filling and the panel is intended for corner installation/assembly exclusively. Only as an exception, it can be positioned freely in the room, particularly in cases where low frequencies accumulate excessively as they can be absorbed very successfully by this panel.

Such panels are very efficient when corners are filled with them completely.

These panels can be used in all types of rooms where acoustics need to be regulated, such as: control studios, vocal recording studios, instrument recording studios, radio studios, loud rooms, music listening rooms, lecture rooms, halls, classrooms, libraries, etc.


The panels are made of the following materials: galvanised steel sheet for the frame, various fabrics and “filters” and acoustic materials, all of them harmless to health.

The standard colours is black. However, when placing a pre-order, all colours from the RAL chart are available. Colours can be either shiny or matt.

The panels are painted with a special electrostatic coating that is baked on the steel, thus having much higher resistance to moisture, heat and scratching.


These panels are easy to install on a vertical wall. In most cases they can simply be placed on the floor and put one on top of the other until they reach the ceiling. If there are fewer panels, they can be mounted with their middle part at the height of sound origin using screws and wall plugs. When ordering panels, screws and wall plugs have to be ordered separately.

Installing such panels on the ceiling requires a bit more effort. Supports to be fixed on the ceiling are enclosed, and they enable for the panel to be positioned as close to the wall as possible. The panel then has to be slid along the supports. Supports have to be mounted on the ceiling with high precision.
