A typical absorbing panel, using 6 1/2" fiberglass AND the rigid panel glued to the rear will be effective down to below 100 Hz.Using only the fiberglass will result in a panel that is good down to around 200 Hz.I don't understand, I've been told by several of the members here, that I can use any type of material at the back of the panel, and it won't affect performace. Now, if I get Jon right, he says that if the back of the panel isn't rigid, performance will be halved.
What am I missing here ?. Is a rigid back mandatory, or can I really use any type of material I want ?.
