Ok Duke,

I saw a picture of L7's with drivers removed on Lansing Heritage Forum.

My pair had a peculiar lower midrange coloration, and some brightness UNLESS I used the Luxman M 117 amp.

I got curious, and removed my cone drivers.

The 8 inch lower mid had just a LITTLE sheet of fiberglass in it, and the upper midrange had a balled up piece of fibergalss in it.

This looked totally different then the one on Lansing Heritage.

So, I decided to experiment with Kapok damping material, additional fiberglass, and dacron.

To make a LONG story short, I am still playing !

I THOUGHT I "had" it the other day, but further listening revealed un acceptable coloration.

Tell me about the amount and positioning of YOUR L 7's damping Duke ?

Ever been IN there to have a peek ?
