The KINO BT SOFT polyvalent bass traps can be used as bass traps, when installed at corners, or installed on flat surfaces, as broadband acoustic panels.
Based on our Kino BT bass traps, they incorporate a textile cover that absorbs the light avoiding the reflections. Due to its extra thickness (120mm), gives an extraordinary sound absorption performance over a wide frequency range (broadband absorption). They are the ideal complement for accompanying acoustic treatments with KINO SOFT panels in home cinemas.
Bass trap designed specifically for the acoustic treatment of cinemas, home cinema, TV sets and broadcast. Specific treatment for controlling and reducing reverberation at low and mid frequency, reducing acoustic anomalies in rooms ('boom' effect, echo...), and as a broadband absorber to control low-medium, medium and high frequency reverberation.
It is advisable to install the same number of bass traps in each corner of the room, to maintain the balance and symmetry.
The following image contains a rough guide with the number of units installed and the degree of sound absorption obtained.

* it is usual to start the installation with the 'light' assembly, in order to check the result obtained. If you want more absorption, add more units to get the 'medium' or 'dark' absorption degree.
