hey,
i need some help finding how far my head should be from the wall, and how far apart my speakers should be.
My room is - 9'9" X 10'1" X 8'
It has a window on the middle of the 10'1 wall
I got 12 bass traps and 8 Broadband absorbers
Right now i have my head around 5 feet from the 10'1" wall with the speakers being 3 feet apart ( there laying sideways and i messureed from the tweeters )
Now when i move my head more to the right, left or back, it seems to be more bass and im wondering what i should listen to.......or should i move the speakers closer and move my listening position closer to the wall.....or is this just normall.
I'll try and post some pics soon*
any help will be appreciated
Thank you

Aloha and welcome to the forum! 
Congrats on your studio build! Any chance you could please:

Also, any pics you could post would help. Thanks!
Setting up the Mix Position
Here are a few bits of information I’ve collected along the way…
• Monitors should fire down the length of the room
• Soffits angled 30 deg. in from a flat wall result in speaker baffles being perpendicular to the two legs of equilateral triangle comprised of two speaker centers and a point about 10" behind your head
• The baffle extension (the face of the soffit) should be as large as you can make it, up to about 45" in each direction from the woofer in a system with a LF cutoff of around 45 hZ - There's a formula based on LF cutoff that ensures full 2 pi response for the woofer if the baffle is at least the size obtained in the formula's solution -
• Monitors should NOT sit on the console but behind, placed on heavy decoupled stands - console placement causes early reflection problems in most cases, unless the console is slanted down in front a LOT.
• Distance to wall behind speakers will change response drastically - there is a wall bounce calculator on the Acoustics forum that's fun to play with (needs Excel)
• Moving either speakers or your head by as little as an inch or two can sometimes make drastic changes in response, due to modal peaks and dips.
• Left/right room symmetry (at least within a foot or two of ear height) is important for good stereo imaging.
• Roughly 38% of total room length from the front wall
• Equilateral triangle formed by left, right mix position
• Monitor angles 60 degrees
• Monitor height – woofer at ear level (avoid mid point of floor to ceiling measurement – either sit higher or lower if necessary)
• Angled side absorption panels – left/right of mix position
• Side walls 6-12 degrees
• Ceiling 12 degree slope
Hope this helps,
Aloha

You'll probably get more of a response by doing so and this will really come in handy two or three posts down the road. It's also part of the forum guidelines:Edit your profile to include your location. This is very important, because this is a worldwide resource, and as such, material costs and availability vary widely. For example, masonry is cheaper than gypsum in some parts of the globe, whereas it's the exact opposite in other regions.
