Thanks everyone!!!! I'm sorry for the couch...hahahaha!!!!! The total cost of the contruction include the acoustic designer(eric arbour (orangenumerik@yahoo.ca Amazing guys to deal with) is 30000$ I do everything by myself. I hired 2 guy for the beginning of the control room to make sure everything was perfectly symmetric. For the control room the design it's kind of live end dead end. The back wall have a lot of roxul in it with 8 hanger. Took me around 8-9 month to build. I'm very happy with the result. Eric has come to do some analysis to make sure is design work 100%. My stereo image is insane...now I can see the sound..haha...It's not a joke! If you have any question let me know...It's a pleasure!!!!
