I have a problem in determining where in my room should be my listening position and where my monitors should be based on that listening position.
Specifically, i am talking about the listening position where my room has the least problems with room modes and where monitors based on that listening position “create” or “produce” the flattest frequency response. And it very confusing what comes first.
I am aware i ll need to move things around and measure with REW to fine tune.
My room size is L 470cm W 310cm H 270cm
You misunderstood me.
I meant the starting positions where i would have the least amount of problems with room modes to begin with. After determining the spot i would start with room treatment with your DIY BDA and so on and fine tune it. The reason why i want to do this is to see how room behaves with the sound source so i know where the most critical spots are. Amroc calculator gives you a clue but it is not exactly like you see but if you play the sound source, you can get a clue. But there is big difference in playing sound source (for example) monitors in corners, monitors on front walls or maybe 1/3rd of the room.
You are approaching this process incorrectly. If you set up now using an untreated room and determine X, then you treat, you will no longer have X. You will have X + – . It is always best to treat first and then set up after treatment. All small rooms need to have two issues resolved: pressure and reflections. Pressure must be managed on all 4 walls and floor to ceiling. Reflections the same requirements. Once you decide on which issues to treat and which to live with, and install the appropriate treatment technology, set up is easy and final with no hoop jumping.
