The DST-112 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. They can easily be cut in half to offer exciting combinations. 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.
