Being that one of MW is in front the rear PR, what is the recommended area(s) to locate the polyfill? Also is it still recommended to put some BH5 (or similar) on the left and right insides of the cabinet? Thanks

    thats is a tough one because of how the CRS's are made, take a look at this thread Dave @westmassguy made about the BH5 damping boards he created on a idea of how to use BH5 in a CRS and he made these for me to put into my CRS's and he did my crossover

    you will in the pics as you scroll down how he put the polyfill into it and it will give you some things to try!

    Your welcome, the damping boards really did help the sound and took some of the shout out of the speakers & gave them a cleaner sound to the mid's.
