I've been doing some research and have decided to build a couple of panels to go in front of my RPTV when I'm listening to music. Basically using the Jon Risch/AudioWorx spec's. I haven't been able to locate Rock wool so I'm just going to use the pegboard method. Is there a reason to use pegboard and not regular board? Haven't found hardware cloth yet either. There's a serious hardware store I haven't tried though. Would "fly screen" material be a valid substitute? It should allow the sound to pass through and be easier to work with than hardware cloth. I also haven't found a huge selection in Burlap colors. Muslin looks easier to work with and it's cheaper. Is there a big difference accoustically? How does one fix the burlap to the frame without leaving unfinished edges that will pull apart? I figured the easiest way would be to fold it back on itself and then staple. At the moment I'm planning to lean the panels against the top bezel of the TV. If the panels too heavy I may have to look at leg supports. Anyone done this? TIA.
