Retractable room treatment
Does anyone know of any retractable or removable room treatment systems for a large wall behind speakers? I have a challenging room, and a wife that won't let me treat it. I'm wondering if there are any sound absorbing screens that fold flat for storage, or any other type of retractable wall treatments?
