Interesting! I suspect that the dried out paper of the cones and the deteriorated dampers significantly change the resonant frequency of the clarifier. I may have to play with one to determine the resonant frequency of the clarifiers on my 37 and 38-116's. If they can be brought back into the designed frequency, they may be more effective in reducing cabinet boominess. Thank you for the link to the original patent!
