.6m x 1.2m x 10cm thickness broadband absorber frame. USA dimensions would be about 2' x 4' x 4" thickness.
Wood Broadband Absorber Frame with picture-frame style face made from one piece of wood (for each side). See my other model if you would like to make it with the picture frame front seperate or if you don't need the front framed. Just wrap your fiberglass or rockwool in fabric and put it in this frame. #acoustic #Acoustic_Panel #bass_trap #broadband_absorber #ceiling_cloud #listening_room #studio_treatment
