The A2 3-Section Acrylic Panel from Clearsonic is made from 1/4" thick acrylic and helps reduce drum bleed into microphones (vocal and instrument) for a better sound experience. The A2 is designed for guitar speaker cabinets. The 3-panel configuration has accordion-style folding for easy storage, setup, and dismantling. In order to ease wiring, cable cutouts are located between each panel.
