Every DJ knows that the music is only as good as the acoustics of the hall/room that the music is being played in. Acoustics is an art of it’s own with ceiling,wall panels, bass traps etc. The most common panels start with a raw fiberglass panel manufactured by Owens Corning. These panels are sometimes used to cover whole walls which are then covered by fabric. The most common line of these panels are called Owens Corning 703 panels. They are available in thicknesses of 1,2 and 4 inches with various facings.
