The DST-114 is part of the Designer Series Treatments (DST.) Perfect for use in rooms where a more designer look is preferred, such as churches, home theaters, recording studios, offices, etc., these 12" x 12" dual ridge square panels provide a great design base. The panels reduce uncontrolled ambience and ensure greater clarity and an enhanced sound field in the surround-listening environment. They come in Charcoal Gray only and can be highlighted with other colors of the other DST acoustic products.
