(Not in the same sound = absorbing compartment.)   I have looked at some Internet pages from companies that sell such materials, and see something that looks very much like thick regular foam used in chair cushions.   Are there any benefits to using a specialized material as opposed to thick =   foam pads?   What about the material used in audio sound chambers?   Thanks in advance,   Paul R. Swank Baltimore, MD.

I have two Moller chests that were already professionally so converted. I had planned to use a third Moller chest (not converted) for = my principal chorus, but I really want to borrow the 8' Principal for the = pedal and the 4' Octave for the swell.   Dennis Steckley "For I am possessed of a cat, surpassing in beauty, from whom I take occasion to bless Almighty God."
