I hope this doesn't come across as a loaded question from a new member. But I have a system that I pieced together that does not include any kind of room EQ abilities, and I'd rather not swap out any components at this time. So I'm wondering how much value there would be in getting a mic and running through amirm's excellent tutorials on measuring room acoustics. If I'm "limited" to speaker placement and maybe acoustic treatment changes ONLY, am I likely to experience significant improvements? I guess what I'm asking is: take someone who feels they made dramatic improvements to their system through a combination of EQ, placement and room treatment. In general, what percentage of that improvement would you say each of those categories gets you? Is 75% of the improvement due to room EQ? Or are they generally about the same? Or is speaker placement the largest driving factor?
