I presently have a GIK monster bass trap & two Echo busters corner traps. The difference they made was quite noticable. I want to take it further w/ more absorption panels, bass traps, diffusion panels, etc. but first I'd like to measure my room's acoustics. With room measurements I can then decide on a plan of action. Did any of you guys do this & if you did how did you do it? I'm not very savy with this sort of thing. Hopefully the simpler the better.
