Has any one attempted to upgrade the internal sound deading acustic padding?

Not complaining, but mine was loosly set in - not adheared to the inner walls, and does not cover the entire inner surface. Was not sure if some upgraded acustic padding covering all of the internal walls would make any difference.

These speakers are remarkable - but being a manufacturing engineer, I recognize that some times short cuts are taken in the manufacturing process outside of the engineering requirements.

Basically I like to tweak everything I own. Any suggestions?

Thanks

Love the speakers - the family now loves to have "Dance night" at least 3x a week, which did not happen with my other speakers.
