Hi vivek
Hearty congratulations on your new room. A dedicated room is a very distant dream for me.
I had saved the below article, just in case I won the lottery someday
Not necessary that one has to go into such depth or expense. But it definitely is a reference level read for me, when it comes to designing a 2 channel listening space. Wishing you all the best
P.S : just my 2 cents, we would all like a large room, but keeping it practical in size is important. Larger spaces will mean a larger investment in room treatment, larger speakers to fill the room, and bigger amplification too.
