I'm wanting to start treating my room this week and I have planned to start with bass traps in my front two corners. I have read through numerous diy threads and sites, but I still have a few questions that I hope all of you can help me with. First I'm debating between a panel style that would straddle the corner leaving an air space behind. The other would be to cut the fiberglass into wedges and fill the corner to the wall. Is one method superior to the other? I would think that the wedges would be better since I would have a significant amount more of insulation, but there would be no space for the sound to pace through and come back. I can not treat my back to corners because one has a door and the other is part of the staircase going upstairs.
I also have base trim around the room. I think the easiest thing to do would be to remove the trim and cut it so that when reinstalled it would butt up to the trap. If anyone has other suggestions I'm all ears.
Concerning the fabric to cover the traps, I know that most people use GOM. I do work at a retail furniture store and have access to a huge selection of fabric. Is there a certain content that I should stick to (polyester, etc.)? From what I have read the GOM is not real stretchy so if I did go with another material I would cover that base. I am more concerned about it being to reflective.
