In Wall Speaker
After a company to ask to acoustics (I have never done this before) and read in a thousand places, I think eventually I'll snap on speakers in the corners myself with the help of a couple of friends and the advice that we draw from here and there. Why? For thus avoid unnecessary reflections of sound coming from the sides and rear speakers and bounces off the walls, which causes certain frequencies to further delay come to our attention and superimposed on coming straight from the speaker, are canceled in perceive the sound side and "distorted", not as they really should be. Right now the structure of the front in wall speaker is of metal profiles (plasterboard) with 8 cm of rock wool covered with fabric. The structure follows the shape of the plane, but the speakers are not embedded, so the idea is to keep everything but the speakers inside the wall. The first problem I've encountered is that the plasterboard profiles can not be used as a framework for the speakers because they are very light and could create resonances. Items that do can use: or SOLID WOOD METAL. Therefore, to start building, apart from having to remove ALL equipment, I have to remove also all aluminum front wall. Due to excessive work in the studio I postponed the work to within a couple of weeks. Soon begin assembling the photos. I have been advised that the first thing I do is to make a in wall speaker perpendicular to the centerline of study. I will use half of metal profiles and the other half of strips of spruce to the "wall" I use a sheet of chipboard 19 mm. What is not is whether I can leave a big hole in the bottom, like a bass trap. This would come to the end of the in wall speaker (so that is not at right angles to the backbone). I acabn commenting that steps should move aside because heat can affect the perception of high frequencies. Tomorrow I will do a test if I have a while to see what happens. Here I tried to put the bottom plate covering the stage . . but no, no, it seems a blind, no?. Even if I move the stage of siege and under a little, just is not so bad, do you think?. . . .
