    Indeed - I made a fiberglass screen "shield" around the 2 woofers to keep the fill from getting into the speaker proper.
    Actually, I switched from polyfill to a measured amount of raw lambswool, based on feedback from my audio guru,
    who explained he'd had significantly better luck with lambswool.

A mesh or "net" around the back of the driver will keep the poly from getting where it doesn't belong (or use a different material that is more cohesive).

    Good deal- I know you're experienced but we all make mistakes and it'd be a shame for such a simple thing to be overlooked. I've heard similar reccs re: lambswool. I really like ultratouch recycled denim batting- easy to work with, holds itself together, etc, and performs similarly to itchy fiberglass.

    Right know these two sources are spread far apart and might not match up well...

    Are Fostex diaphragms available any more? I can't seem to find anything with a Google search. I'm dealing on a pair of D252 drivers, but if I ever blow one they become pretty worthless if I can't get a diaphragm. I have a pair of pine H425 horns.

    Nope no diaphragms available, so be careful. Pictures of your Horns and drivers would be great!

    Best regards
