I searched using a few different words, but couldn't come up with anything for this model. Seen numerous 5's/7's/10's crossover upgrades... just not the newer ones.
My quest began last week, as I picked up a pair of Black Ash Mon7 SeriesII speakers. Wood grain is in pretty good shape, though I'd like to try reveneering someday. Don't expect to see that in this thread, though.
Applied Mortite to the drivers already, and dynamat on the PR. For those of you looking to do this upgrade... save the Mortite for LAST. This may seem obvious, but I was excited to get cracking on these, and the Dynamat/Mortite was all I had available to begin the mods. Now I'll have to yank them off to get the drivers reconnected after the Crossover is finished.
