Position of Basstraps in bedroom to mixroom in Argentina

Hi. I'm new in the forum. My name is Matias and I'm from Buenos Aires, Argentina. Here is an SketchUp file that I made of my bedroom trying to transform it a little into a more decent room for hearing and mixing... So I wish if you see this layout to give me the "ok" or give me some help, and there are some tips that I'd like you to see: 1) All panels that are in the front corners, front wall, side walls and roof are bass traps. So the questions is: are there in right place, I mean, in height is this right to put this in the middle of the wall or just in the middle of the height of the speakers? 2) There are two deflector made of 1/4inch plywood in the front and fiberglass cover the air space, on the rear wall and the right wall. So the question is: are there in correct place? I mean, the side wall deflector is to deflect the reflections of the window on the left wall, but I think it will make a difference in the stereo imaging, aren't it? The windows has cortains, so is it better to put another basstrap instead of deflector? I guided from this forum and from the realtraps articles of Ethan Winer to make calculation of the position to get the Reflection Free Zone. I know the room is very small (3.85m x 2.20m x 2.67m), but this is my bedroom and I'm trying to get the best sound that it can putting some absortion, so any suggestion is well recieve. So, thanks for reading this, and sorry about my English! Bye!

Hola Matías, y bienvendio al fóro! Yo soy casi vecino tuyo, en Santiago, Chile. Pero voy a continuar en inglés, por respeto a todos los demás miembros aquí. Otra cosa: Para que te contesten aquí, debes leer y seguir las instrucciones aquí.. Muy importante. Por eso nadie te respondió. Matías, your basic layout looks good to me. To answer your questions: Your bass traps are fine, but they can be bigger. They will be more effective if you make them all the way from the floor to the ceiling, and make them deep. Put in lots of rockwoool ("lana mineral") or fiberglass. As much as you can. In fact, if you can afford it, fill the entire corners with triangles of rockwool, from floor to ceiling. For bass traps, bigger is better. However, if the size that you show is all that you can afford, then I'd move them up so they are touching the ceiling and only come half way down the wall. The reason is because room modes all come together in the corners, so putting the bass traps in the "tri-corner" where both walls and the ceiling meet, is more effective than just putting them where two walls meet. You could also put bass trapping in the wall/floor corner at the front of the room (where the speaker stands are)

There are two deflector made of 1/4inch plywood in the front and fiberglass cover the air space, on the rear wall and the right wall. So the question is: are there in correct place? I mean, the side wall deflector is to deflect the reflections of the window on the left wall, but I think it will make a difference in the stereo imaging, aren't it?

Your diffusors on the front, back and side walls are not really necessary in such a small room. I think it would be better to place additional absorption in those positions, especially on the rear wall. I'd suggest putting a bass trap all the way across the top of the rear wall, above the bed and closet, and absorption underneath that, on the wall where you have the plywood diffusor at present. Your room is not symmetrical behind the listening position, but since it is your bedroom there isn't much you can do about that! Besides, the rest of the treatment is going to make a BIG difference to how your room sounds, so I wouldn't worry too much about the rear. If it really concerns you a lot, then maybe you could move the closet and the bookshelf out, but since it is your bedroom, that might be a problem!!! Besides, I don't think it is a big issue. You might want to put some absorption on the closet (the side that faces the speakers: the doors), but once again, I'm not sure if it would help much. Your windows: It looks like part of your window is at the first reflection point for your left speaker. Maybe the best thing you could do here is to build absorbers on wheels, sort of like a gobo, that you can wheel in front of the windows for critical listening, and wheel them out of the way when you want light in your room! Make two of them: one to go in front of the window, and one to go in front of the wall on the other side of the room (where you show another diffusor), to keep things symmetrical. As long as it covers half of your window (the half away from the bed), that should be plenty. Apart from that, it looks good! Suerte con la construcción!
