    Any idea where I can find "lead-bitumen"?
    Anybody know of any other names for this substance?
    Anybody know of any good substitutes?

    In this article lead-bitumen is used to seperate two layers of MDF. I have some Focal (JM Labs) 6.5" midrange speakers kicking around with a couple of JM Labs titanium tweeters. I would like to put them in a box similar to the one in the article mentioned above but haven't been able to find lead-bitumen anywhere..

    Thanks in advance

    The Andromeda is a fairly over engineered speaker design! I'm not sure how much difference you'd notice over a well braced, double thickness MDF cabinet. Especially if you're not going to be putting some big old woofers in there.

    Anyway, I think your best bet would be to try roofing suppliers, something like
    these people.

    You might get a better answer at www.diyaudio.com, they're a very knowledgeable crowd over there.

    Mac.
