I'm interested in treating the primary reflection points in my listening room, but those spots also happen to be the locations where I would like to hang some art.

I realize that fiberglass can be used as absorbers to a certain degree, which is what most poster frames use as a practical solution for glass. So if I could use a frame to not only treat the room, but make the room look pretty, that'd be great.

But how effective would it be?

Are you referring to Plexi-glass or fiberglass?

Posters are a bad idea for early reflection treatment. The paper reflects high frequencies, which are the one that need to be absorbed. The only way I know of to have your cake and eat it too is to have poster images silk-screened onto fabric, which then covers fiberglass absorbers.

Huh? I think the previous poster is right, you are confusing plexiglass with fiberglass. I have never seen any kind of poster frame made from fiberglass. Obviously I have seen many frames covered with plexiglass as opposed to glass. Plexiglass is a clear plastic, like a window.

Fiberglass is not anything like that. Fiberglass is the insulation that is in your walls.

Plexiglass is reflective, as you can imaging, much like glass is. This would be an absolutely terrible absorber and totally not appropriate as a treatment unless you WANT a large, flat, extremely reflective surface (extremely unlikely). Fiberglass is a fluffy like material, opaque of course. It's more like cotton/wool, or dense cotton/wool if made into more dense fiberglass type boards as the lower picture shows.

BTW: the bottom picture i stole from ethan's site, the other two i stole from the interweb.

Thanks for clearing that up guys.

I prefer my art plax mounted anyways...
