Timely thread, I have some basic room treatments, two corner bass traps and four 244's base traps all GIK. I went thru the room analysis with GIK, placed an order for two more corner traps.....to start. Based upon GIK recommendations, I put two 244's on each side wall at the first reflection point.....it made a noticeable difference. I am hoping that they arrive undamaged, as some, as experienced. And I was told shipping was 8-12 weeks out.....that's OK.
My room is a dedicated 20' X 14' in the basement. I did not do double dry wall...instead, the non-foundation walls have staggard studs, and the dry wall on the ceiling is on a track system. There is a solid core door, rarely closed.....thanks to our dogs.
Anyways, I plan on following GIK's plan and believe the end result will be nice surprise.
