Adding Polyfill to a speaker cabinet. What to expect?

The MBL101E tone control is implemented switching among different types of wire between the crossover and the drivers - you can read the description of its effect in the Stereophile review.

Don,

I think that's exactly what occurred.

Bare in my mind I might have decreased the overall cabinet volume by maybe 5% or so but it's quite audible and to the good I think. Need a bit more listening time but this seems to have helped mitigate the issue.

Awesome, I love it when a tweak works and makes technical sense!
