      wedge recording room absorbing foam
      greesound Homework 2" Wedge foam is the best choice to improve stereo imaging, and fix problems with high frequencies.
      Because of the deep-cut wedge shape, it soaks up more sound, leading to better frequency profiles, and therefore better overall sound.
      The 2.0lb density, 2" thick, Class-B flame retardant acoustic foam is ideally suited to absorbing mid and high frequencies.
      Specification:
      Size:30.5cm*30.5cm*5cm(thickness).other size can be order by request.
      Color:black/white
      Density:22kg/m3
      Flame:fire resistance
      Deciding how much acoustic foam your space needs can be complex. In most cases, you''ll want between 25% - 75% of the walls and ceiling covered.
      You might want closer to 25% if you have a lot of furniture or draperies in the room, or you want a more "live" sound.
      You might want closer to 50 or even 75% if you have big problems with "flutter echo", or you want a "dead" sound.
      100% coverage is best for vocal booths - in other spaces, it will sound unnatural.
