Room Treatment experiment

Gammajo
A simple method is to have somebody hold a mirror and moving along the walls while you are sitting at your usual listening position.Every time you can see the reflection of your speakers,that is a first reflection point and that's where you place your treatments.
However I am only repeating what I read from other people comments.Try and see.

Yiasou Yiorgo!

go to this web sight http://www.atsacoustics.com/cat--ATS-Acoustic-Absorption-Panels--100.html.these are real cheap to try,your room looks very hard to me,you can get these roomtreatments and put the big ones behind your speakers,and if wife dont like them you always can put them in the closet when your not useing.all that glass is another thing,curtains with backing will work.i to share a room with family,and the wife let me keep the panels up behind my speaker,there are 4 colors to pick from ,so i let her pick it,as my first reflection i have a nail in the wall and when i want i hang themup,when finished put them in closet,for the price of these there cheaper than building

Thanks. I explored the site and they look like the way to go for cheap and moveable. I'll give it a try
