Dimensions l: 380cm w: 280cm h: 240cm Desk and wardrobe's matter is MDF. Wardobe's height is 210cm. There is my some stuff on wardrobe and no left space to ceiling. Now, I think to place 2 trap to front and back of listening position and 2 corners. I guess, here is no problem. A corner is really small, 5cm. Should I place a trap there? It will really difficult to place, if I must do it. Because the door :) Wardrobe is almost touch to wall and corner, 2cm space. Is this corner need a trap too? I will put trap to corners from floor to ceiling. The traps are rock wool with coating MDF, about 4-5cm thickness. What should to be width and gap?
hai, first: Look at the sticky threats. READ, fill in your form, Learn, design and review. IF you've read this forum you'll prolly alter your design which looks like; - mixdesk in front of the window to shoot monitors in the long axis of the room - move the wardrobe to the opposite wall of your desk, next to the door and add a thick absorber on the wardrobe's door to create a basstrap. - add a 5cm thick absorber onto the door and leave the 5cm corner for what it is. - fill the remaining corners with a descent basstrap. - make use of all corners if you like
Thanks for your answer. I posted the message after read the stickies. So, do you mean this?

My english is not very well. I'm drawing because that, am I understand right or not. Actually, I prefer this design in my room if it's possible. I don't want to close to front of window. Is this possible?

If this is possible, can you tell me (or a simple draw) where I should place the traps. I can move wardrobe to left way if necessary.
Welcomed to the forum. The first plan is the best with the window in front of you and the wardrobe on the rear wall. Hang all your clothes in the wardrobe and remove the doors. :) Unfortunately you will need additional absorption. Demetris was able to purchase this product in Cyprus so I assume it's probably available to you in Turkey.

There is a radiator under of window (not moveable) and sun is directly coming from window. It's really hot for computer. I think it will overheat, dangerous for pc. This think is making me uncomfortable :? I was thinking like this,

May there isn't mobile trap. Why you propose that window is back of speakers? For wall bounce or something else? What should be width of corner traps?
The problem with your second layout is that it is not symmetrical. Room symmetry is very important. Without symmetry you cannot get an accurate sound stage, and your mixes will not "translate" very well. Also, with your design, you have a hard, reflective surface right behind you: the window. You will get reflections off that coming back to your ears. There are a couple of other reasons why I would not go with your second layout. As John already said, the first one is much better. - Stuart -
I understand. Thanks for your advices.
Yes, stick with this design:

It's gonna be hot in the room anyway, it's a small room and it doesn't matter where you put your computer for that matter. Just add blinds too your window if you like. You can also make use of the corners between wall and ceiling, you know?! It'll save space. And John had a good point on the wardrobe ;) Or loose the whole darn cabinet... put your monitors on heave stands, behind the desk. Add good basstrapping in the corners since your room is tiny. Follow the acoustic threats closely to learn

I wish I was a girl :) More clothes, more absorption. Lucky girls :D What should be corner traps width? Still no answer :?
depends on the wool for practical reasons. If your wool is 120x60cm for example, you can cut it into half en cut those half pieces into quarters using a diagonal cut. Then your width will be 60*60cm :) For basstraps a 50x50cm is a starting point, more wool is better low end absorption.
