My biggest problem is definately not really knowing what to do or where to begin. I picked up the AVIA disc and it helped a bit, but I really just don't understand the whole process of sonically tuning a room. I actually tried a few test tones, but didn't get the whole thing with charting it and have no clue what the chart I came up with means.
Second to that is I am currently renting and would like to buy in a year or two. So, I really don't want to invest a lot of money into the tiny apartment I'm in (350sq ft) for better sound.
