Hello everyone,
Just got finished using and abusing this site to help me finish my sub. I ran my first tests with REW and did my first EQ with the BFD, PDQ. hehe. Anyway, my question is: Now what? Do I start to add room treatments based on my response? I have another couch to buy and some curtains to put over the windows and I am sure this will effect my response. So... do I just wait, then run some more tests and see what it looks like? How does one determine when treatments are needed? Say I had a poor reponse (which I don't know how that looks), how do I know what kind of treatment is needed and where to put it. Is it a trial and error thing, or can you look at a response curve, look at the room, and say, "hey, I need a bass trap here?"
Just for kicks, here is my first EQ's response and the response from listening position with no EQ.
