How do you measure a room for treatment ?

dude, yesterday there were TWO threads with how do roomtreatment content. u dont even need to search.

http://www.realtraps.com/ ->starting point for speaker placement
www.hometheatershack.com ->additional info and REW

standard treatment would most likely look like: diy bass traps (rigid fiberglas or rockwool) in 4 corners from low to ceiling, diy broadband absorbers (rigid fiberglas or rockwool, there COULD be a foam for broadband absorbtion....) to left, right and ceiling. your room doesnt look like its huge so a diffusor COULD be of high priority after the two things metioned above. further info ->link
