Bill, the 6 " of Sonex will do nothing at 60Hz. If you look at the absorption diagram of Sonex then you will see that it is has very little effectives below 300-400Hz. And of cause I will not use notch filters. The notching must not be used in pass-band – only in open-end applications. This is one of the Macondo's Axioms pastulates.
