I am about to build my room and I really like the screen walls where the sides start out a bit from the wall to enclose the L,R, SW and center speakers around the screen. I am wondering how many of you are building the fabric panels to cover the speakers? Are these made like regular speaker panels, with the normal plastic ball and socket joints for quick removal of the panels if necessary or are people using velcro? If so where are you sourcing the fabric and connectors? Any details on the materials and attachment method will greatly help my construction project.
