Sonopan Accoustical Panel vs Rigid Fiberglass

Has anybody ever used Sonopan Acoustical panel instead of Rigid Fiberglass sheets to build bass traps with. Is one better than the other? If you have used them what type/size of trap did you build and what frequencies did you think it effected..

Also, has anyone used either one on a low basemet ceiling to help with reflection and bass.? Do they work well etc..
thanks

I have not used Sonopan panels but I have used rigid fiberglass and bonded acoustical cotton.

Our limited tests proved the cotton to be superior but only by a slight margin and at a considerable price difference.

So if you are on a budget then rigid fiberglass of say 3.0-6.0 pcf would be the best way to go. Get at least 4" thick for bass trapping purposes - 1st reflection points can use 2" thick material.
