I am having problems with my listening room making some nasty high frequency peaks, that's probably not the best term, but basically 2.5-3.5 khz frequency range is generating a 'scream' factor to music, mostly heard in high pitch voices or guitar solos for example. Having read up a bit its seems 1 inch rockwool type panels would be good to reduce this issue but there are various types and makes to chose from. A rigid board would be a lot easier to install, so 25mm Rockwell Rockfloor seemed a good choice but then the Knauf RW3 60kg wool on paper sounds a better product but harder to work with.
Has anyone any experience of one type of insulation board over another, or should I not get hung up on such issues and just go for the easiest to install option ?
