Good timing for this thread- I'm finally dipping into the world of treatments.
I've rearranged the furniture in my listening space, and the midrange is now killing me- it's much brighter than before. Unfortunately, the room is mostly plaster and lathe, and the left speaker is only about 2 feet from the wall. I've relied on the furnishings before, but now I need some panels!
I have a friend who didn't believe in treating a room, at least until I showed him an extreme example of just how important doing it is to do SOMETHING. When I moved into my house, the family room was completely empty. Just plaster walls and a hard wood floor. I tried to set up my new out going answering machine message while standing in that room- it was completely impossible! The room was so live that nothing I did worked. Even with my mouth pressed against the machine, you couldn't understand what I was saying.
After I threw down a carpet and moved a couch and piano into it, I was finally able to set the outgoing message. It was crazy!
I've already double hung curtains on the back wall which is a large grouping of windows, and there are a few pieces of puffy furniture as well as a book shelve, but the wall on the left is untouched. I'm confident that a few panels will take care of business and get the plaster out of my midrange.
