The ClearSonic A5-5 is a 5-section drum shield. Each section is 2' wide and 5.5' tall. The A5-5 will usually cover the front and sides of a standard drum kit. To be fully effective, ClearSonic panels should be used in conjunction withSORBER baffles. Remember, ClearSonic products are modular, so the A5-5 can easily be made larger, or even turned into an IsoPac.
