The Auralex Sonolite panels are a fantastic set to go with your home recording studio. The panels themselves are made of an either tan or black fabric, depending on which you would prefer. Working best with acoustic sounds, the panels absorb an amazing amount of the sound to prevent it from bouncing off of the walls. The panels come with the mounting tack. When combined with the Sonolite Bass panels, they cover a wide range of low to high frequency control. They can be mounted on any flat wall or even the ceiling.
