Re: Jon R: painting acoustic panels

Paint on any acoustic surface is a no-no, and will cause HF reflectance.

First, check out Wal-Mart for the different colors of burlap (it may be called jute), they have green, blue, red, yellow, brown, natural (sort of a straw or tan color), and off-white. They may have other colors, and I can not remember if they have black or not. One of these colors may be suitable to your wife.

If not, then check out a fabric store, and see what they have in the way of burlap or jute in colors.

Failing both of these, speaker grille cloth can be used, and will perform better than painted burlap. There are many different sources for speaker grille cloth, including RS. Just be sure it is being sold as speaker grille cloth, and is not just some random double-knit polyester or other fabric that is called grille cloth by some local vendor.

Realize that anything else will affect the HF reflectance, and this will make the wall panels less effective. It would not affect the bass traps as much, especially if that was all they were going to be used for, and there was no concern for using them in other manners along the side walls, etc as indicated by ASC. If you were to paint the bass traps, it might be OK _IF_ the paint did not fill up the fabric holes, as once this occured, they would no longer function properly. In the case of a painted bass trap, you should omit the layer of plastic beneath the one side.
