Many of the rooms in which they are the monitors facing the problem of inadequate acoustics. Blank walls, bare windows, a small amount or a complete lack of furniture, stark interior - are the main elements that negatively affect the perception of music. Very long reverberation time and thumping bass dominant in the transmission of music is only a small part of the problem. In such circumstances, it is almost unattainable to achieve full potential of your system - both financial and composed of components of the highest class.

Rather than fall into the trap of wasting time and money on testing the next column or investing in expensive cabling, much better and noticeable immediate effect is to install regimes modifying room acoustics.

By installing the panels in the corners of the room listening obtain improvements in the lowest frequencies, such as reducing the beats, which results in increasing the transparency of the sound system. Installing the panels in the first reflections of the signal (the side walls and the wall behind the columns followed by wall and ceiling behind the listener) is beneficial for improving the stereo and the location of the virtual sources in the transmission of music. Often there is calming sound of the sharp-sounding systems with excessively.

Another function of damping panels to reduce reverberation time RT60 listening room. RT60 optimal value fluctuates within the range of 0.4-0.6 s Too much reverberation time that blur the soundstage and significant impairment in stereo. It is important to avoid excessive damping of the room - in the natural environment, to our ears, but there is a whole bunch of sounds reflected - the excessive elimination will cause the system will sound unnatural "hollow"

BROADBAND ACOUSTIC PANELS diffusely - damping GRAND / PICO

A series of unique panels that combine the ability to attenuation and scattering of the sound wave incident on the system. The most advanced adaptive acoustic characteristics of the room.

Available on the market can be divided into panels and damping incident on the scattering acoustic waves. What distinguishes our solution against the competitive products is a combination of absorption features (effective absorption from 150Hz) with the diffusivity function. As the absorbent material is a combination of wool acoustic use high density foam with a thin layer of acoustic aesthetic hidden under the upholstery material. Moving diffusers allow the user to control the degree of dispersion in relation to the degree of attenuation, which gives great opportunities to create the ultimate end result.

We warn all against the use of low-cost solutions based on the use of sheets of foam (pyramids, cones, cones, etc.). Apart from the purely aesthetic qualities - the foam will never give even close to the results of the action panel built on the basis of fibrous materials with high density.

Key features and usability:

Versatility - a combination of scattering attenuation. You can adjust the damping

Mounting system adapted to each type of substrate (concrete wall / wood / plasterboard). After the initial attachment position is adjustable in a horizontal plane within + / - 12cm

In order to perfectly match the decor of the room panel, you can change the color of the frame and upholstery fabric.

A range of models:

PICO-6 panels with a thickness of the damping layer 6cm - minor correction of the acoustic environment in a pre-arranged public listening in home audio-video systems. Dedicated to smaller spaces. Dimensions - 56/56/6cm.

GRAND-6 panels with a thickness of the damping layer 6cm - variant intermediate between that model PICO-6 and GRAND-11. Dimensions - 73/124/6cm.

GRAND-11 panels with a thickness of the damping layer 11cm - advanced correction of the acoustic environment in large audiovisual systems - "empty" rooms with areas larger than 20m. Dimensions - 73/124/11cm.

Panels CORNER-7 7cm thick layer damping panels - to be placed in the corners of the room, to help in mastering the bass. Dimensions - 73/124/7cm

The chart above shows the effectiveness of suppression by a panel of G11 sound wave incident on a brick , plastered and painted walls. The sound source was directed to the wall at an angle of 45 °. After reflection from the sound wave is recorded by measuring microphone put under an angle - 45o ( minus 45 degrees ) . The way that overcomes the sound wave from the source to the microphone is about 1m. In addition, between the microphone and the sound source was placed baffle insulating effect of the wave that she could go directly into the microphone , distorting the measurement of the intensity of the reflected sound. 

On the characteristics can be observed two characteristic phenomena that significantly affect the performance of the panels :

1.  Small, although there is a noticeable attenuation in band bass to 100Hz panels start to work very clearly ( above 3dB attenuation or elimination twice reflected wave ) frequencies from 200Hz . Very important is the fact that the frequency of 1kHz panels operate in a linear manner , suppressing a wave reflected by up to 8 dB . The linearity of the attenuation is extremely important to the operation of the whole system. With such behavior panels do not cut down the treble band but eliminate reflections evenly across the audio band .                                                                                          

2.    Gray waveform shows how, in the context of the reflected sound attenuation is often used  behaves acoustic foam formed into suppositories. It is clear that such a solution to the frequency of 1.2 kHz has no effect . The effect of leveling the effectiveness of the two approaches we see only at a frequency of 12kHz ! It can therefore be concluded that the sponge suppository is not a good solution because it does not  work in the field that usually causes the most problems .
