Acousta blue + / No Rez

Hi
I saw a GR video on upgrading some Revel Monitors and one of his hacks was to line the speaker with No Rez. I bought some Acousta Blue+ from Parts Express and lined my Revel M16 with it. Definitely made a difference to the extent that I had to stuff polyfill in the port. Too much bass. Not boomy just a little too deep for my bedroom setup.
Thoughts?
