Welcome to sE Electronics
Does this really help prevent low frequencies as well as high?
I have a room that is pretty dead, but I do still have problems with some reflections and a little bit boxy, boomy vocals. -What I have now is glassfiber behind me in a "diamond" shape, I also have a glassfiber-cloud above me and the mic when recording. I do also have wooden walls and sealing.
Is this thing a good complement to get rid of muddy, boxy vocals?
