Glad to hear.
Hope I'm not high jacking your thread but this seems the best place to post and I'm sure you will do a much more thorough test.
SO here is my 2c worth of test with my $150 bucks of materials and CL.
So I did a number of readings with fuzzmeasure.
(Also to note I might not be doing my test completely right because I'm new at this. I just did a "what I think" calibration with the ECM 8000 pointed up. The mic was about 2/5 from the front of the room facing up towards the 8' ceiling. I should Point out that it was facing the ceiling right where a 20" deep sky light meets a ATS 2" panel mounted flush making a T)
I saw no difference with two 3' by 15" capped or un-capped tubes in the back of the room and next to and about 20" below the mic. I didn't get fluffy filling because of spending more cash and the public transportation trip.(sorry no car) To note they also were not mounted mic/speaker high which I think might have made a difference AND they still had their original aluminum covering which I wasn't sure would through the whole test out the window.
I did notice a big difference between my readings with doors open and closed so make sure you close your doors.
Next I place four quarter rounds that are covered with material and backed with 1/4 wood, around the mic and found an evening out of 5 db around 70hz, 170hz and between 200 and 500hz on my measurements. It also sounded great. I put reflective material on two of the quarters. It sounded somewhat absorbent but not dead like a vocal booth.
In hinds sight I wish I didn't cut up as many 15" rounds and used them more like what ASC designed them for. I'm trying to make my living room into a tracking room when friends stop by. Having a room that you can change to meet different situations would have been the best for my needs.
