help/advise on my room setup (pic included)

[masoodkhodayi]

hey guys

this is my first-ever setup for a 12 sq/m2 sized room , can you help me about best location for speaker monitors ( YAMAHA HS8 ) and also acoustic treatment ? my windows have a vertical curtain in front of them , can i install acoustic foams on the curtain in front of windows or i must install them directly on glasses ? ( acoustic foams shown in colors with a map legend ) glass thickness are about 3mm

any pro advise will be appreciated

thanks

Hi. Please read the forum rules for posting (click here). You seem to be missing a couple of things!

can you help me about best location for speaker monitors

First, get the orientation correct. Rotate the orientation of your room 90° to the left, so that it is facing "down" the page, with the from of the room being the yellow window. Now set up your speakers and mix position like this:

Neither. That would not help much. What you need in that room is major bass trapping, in all four vertical corners. Make "superchunk" style corner traps there, using OC-703, and install 4" thick OC-703 panels at all first reflection points, plus across the entire rear wall.

Be very careful with cheap "foam by mail" vendors. Most of that stuff is useless, acoustically.

hey Soundman2020

profile got updated sir

thnx alot for answer & those sketchup designs ! that was really clear and helpful answer !

seems like i gonna need some bass traps then

i will change the orientation so that speakers fire along the long side of room and set speakers as u mentioned , if i do these steps do i have to worry about the windows @ the back of my speakers and also the one which will be on the left side speaker ?!

i searched about this article alot on net but some say window is beneficial and some say not! really got confused on this

I have a feeling you might be our first member from Iran! I'm not aware of any other members from there. Welcome!!!!

We'll get to treatment later, after the initial test, but yes, there acoustic panels behind your speakers might partly cover the edges of the front window. The window on what will be your left side should not be a problem, hopefully, as it seems to be a bit behind the first reflection point. But even in the worst case, the panel would only cover part of that window.

Acoustics can be confusing, yes! But think of it this way: glass is just a fairly rigid, heavy building material, so it is not very different from drywall, wood, brick, and similar things. Yes, there's a difference in the mass (surface density), but the reflections from all of those are similar. Not a huge difference. So it is neither a lot more beneficial, nor a lo more detrimental, as compared to other building materials. It is sort of the same.

The real issue is not so much what the wall is made of, but what to put in front of it to control the acoustic problems: from that point of view, there's no difference between having glass, metal, brick, wood, drywall, or concrete behind it. The issue here is first reflections, and they need to be absorbed, regardless of what is behind the absorber. Building materials are important in other parts of the room, and also in all parts of the room for other reasons, but for first reflections, there's not much difference. It's the treatment that matters, not so much the building material behind it.
