If we asked audiophiles which element of the stereo system is the most important in their opinion, most of them would definitely bet on speakers, an amplifier or a source, or - in some cases- on something like cables, power accessories, or anti-vibration pads. A large group will answer, however, that the room in which all this equipment works has the greatest impact on the final sound result. In a room with poor acoustics, even the most expensive and the most refined equipment will not be able to show even some of its capabilities, while in interiors adapted to listening to music, even inexpensive equipment should do well and give us a lot of pleasure. What to do to find ourselves in the latter group? There are, of course, many simple home methods to improve acoustics, but more and more people are choosing a "real" solution - the assembly of professional acoustic panels. There are many companies on the market offering specialized products for the adaptation of room acoustics - not only listening rooms, but also recording studios, concert and conference halls, offices, hotels, restaurants, and public facilities. One of them is Vicoustic. The Portuguese have long been providing audiophiles, sound engineers, and installers with panels that do not look like typical, ugly, gray pieces of foam. A lot has changed recently, so I decided to explore the subject in more detail and talk to Vicoustic's technical director, Gustavo Pires.
