Material/technique to substitute facing on fiberglass ?

Hello all, Just picked up some OC703 and in the process of making bass traps. The local distributor only had unfaced. Is there a proven material I can add to these panels to reduce High freq absorption while maintaining or increasing the low? thanks

All you get is a low, just one, and that's it? I located a few links that seem to be made just for your situation. Actually you had to trip over it to get this far in the forum ;) http://www.johnlsayers.com/phpBB2/viewforum.php?f=3 Oh your going to need more then this, but this is all I have time for tonight.

yes, adding a plastic sheet will do. As X mentioned, there's a lot of info here on the forum. Read and you'll find the answer... may the force be... ah, whatever
