Acoustic absorber panel question


Referring to absorber panels (fiberglass covered with fabric): I see a huge difference in cost between panels from various manufacturers, specifically between the big commercial outfits and the "cottage industry". Of course Mr. Risch has shown us how cheap they can be made. Can I get equivalent performance from the inexpensive ones as I can from the big name commercial ones?

Best bang for the buck I've seen for anything but bass. http://www.readyacoustics.com/index.php

In the process of building DYI membrane traps now. Three of them cost about the same as one commercial unit but I used solid oak frames.

Yes, you can. MDF substrate & melamine laminated panels are very inexpensive compare to others but acoustically very effective. Please visit  www.acousticmanufacturer.com/Noise-Barrier-on-Temporary-Fence-for-Construction-Site.html. Here you will find visually attractive, acoustically effective panels at a very competitive price.
