Why not DIY? Its incredibly simple. You buy duct board and wrap them in fabric for simple ones. Others have made much thicker panels that absorb more freq's. Brian

I'm planning on building it myself... buying these, or similar panels, and wrapping/framing them with somthing. I was inquiring about these particular panels - the performance, cost, where to buy - or other specific options. What's "duct board"?


Anyone with some usable feedback?

It is a rigid, porous weave of fiberglass fibers on a reinforced foil backing.

Here is an article with a picture.


BTW,dctboard is falling out of favor with AC systems due to it's porous surface being a polace that "stuff" can collect. It has other advantages, though.


Best regards,

Doug

Western Macarthur in Oakland (2855 Mandela Pkwy) carries the Owens Corning Select Sound line and the JM Linacoustic Permacoate rolls. Ask for Gerald (510/836-0600).

Duct board is what they typically build return air plenums out of. Its also basically what the professional panel companies use. It comes in various thicknesses. Check the pages of the acoutic panel companies for the sound coefficients on their panels and you should achieve similar results assuming you use the same thicknesses. They have an extra process though where they coat the edges in a hardener that keeps them from denting or damaging easily.


Now if you want REAL acoustical panels try some of the recipes cooked up on this forum and in other places by the likes of Ted White. Just do a search for DIY Acoustic Panels.
