I'm planning to treat my room. I just had my room finished. Its 12x7.25x19.58. I posted the question before but didn't get any response. So hoping someone will help me out this time. I can ask in other threads but the beauty being on this thread is that if anyone is telling me what to do here, he knows it works because most likely he tested it with REW to see before/after impact.
After reading in different threads, its a common agreement to
1 - Cover Front wall completely with 1" linacoustic.
2 - Cover Top/Left/Right wall with 1" linacoustic up to where the front speakers will be placed.
Then handle first reflection. For that I'm going to hang panel that I made using 2" Fiber Glass on side wall. For celing I'll be using 4" Roxul mineral wool. I'll be taking before/after reading to see the difference in
Now comes the low frequencies. I made my own bass traps using two layers of 4" Roxul mineral wool. So basically, 8" of Roxul mineal wool covering corners. How effective is it? Well when I took reading, it made FR better.
But I have been reading around one one issue that's catching my eye is that these Home Made bass traps will not only absorb low but also high frequency which can make room sound dull.
I'd like to know if its worth/better to buy commercial bass traps like this one http://realtraps.com/p_mondotrap.htm?
Also, how can I tell using REW that the room is over damped? Using Impluse, one can see if there is too much reflection (anything going above 20) but is there a way to know if room is too damped?
