| i would put up the absorbers you have first before making more that you may not need....but, if you are going to make something before you put up the other absorbers, make bass traps....you can never get enough of those especially in a room thats really live.
in any case, yes, rockwool is fine...in fact its the only thing you can get in the UK. lots of people use it..including me.
i would make 2' 4' wall panels of 2" rockwool. since it comes that way...and you want to have first reflection stuff a bit larger than it needs to be for good measure. ( to clarify i mean bigger than you were talking about making, and when i say 2' x 4', thats in feet not meters....) |
