Acoustically Treated Surfaces

The combination of padded walls and fabric covering is the most acceptable way to acoustically correct the reflective sounds on hard surfaces. By intermixing your choice of fabric styles and textures with your furniture, draperies and walls, your home, theatre or other any other room, will take on a luxurious look complete with rich sound while drastically cutting down on outside noises such as traffic, planes and other unwanted distractions.  Your unique room is sure to attract compliments and imitation.
