Hi,
Well, the highs seemed clearer and the mids were more open.
Over all an improvement and now have done everything possible to help them sound as good as possible.
Worth the money and effort to me.
Cleaned the wood and stained with black leather dye, did not want more paint on to hide the wood grain.
Installed a grill on the back to protect the passive.
Later rubbed in some Howard'sFeed and Wax, and was done.
