    Seriously though:

    Has anyone used these tweeter tweeking products?

    If so what brand or type and a link to their product would be nice.

    I have read a number of articles on the subject (many google searches) related to these type products, also have seen some measurment and graphing showing that some of these products apparently actually work quite well.
    Some though making the on aixs and off axis response even worse!

    They (supposedly) deal with reflections off the tweeters baffle and help to control a smoother response dispersion.
    Many DIY'ers and experimenters seem to make their own many times. A certain type of wool is supposed to work better than felt or rubber/foam type products.

    Might anyone have experience with this or a type of product that is similar, and whats your take.

    Regards

    Geoff,

    ThomasW uses "Machine Gasket Material" aparently it's
    fairly expensive stuff but it's real dense wool and you
    can seperate it into thinner sections..

    The baffels of my 9's are completely surrounded with a
    Dense Cellular Foam that helps the tweeters radiation and
    it works, I have tried them without the foam on and they
    image like crap.. Here's what the baffel looks like..

    Yup, Exactly...I have been experimenting with some different type materials and there is definitly a difference!

    Where dose he find this machine gun material-stuff (in sheets I assume)?

    I also read that TI-33 ? wool sheets or something like that number, and (another # type) is the best.

    Geoff,

    I think he gets it from McMaster Carr or some other Machine
    Tool supply company. It's meant to make up gaskets for
    machine equipment (Lathes, Mills etc) I guess it's some
    sort of very dense wool product or a mixture of wool and
    something else.

    You could also try the Dense Acoustic Foam tiles PE sells
    or maybe even Black Hole 5 could work.... Experimentation
    is the key I guess.

    Yes I am familar with those but not what I am looking for. They changed the design of those I belive just last year in both the material make up and from a circle to a more oval design. Some people do swear by them, but again not what I am looking for.
    Thanks for looking for me though!

    I have a few friends in that line/type of work and will ask if they are familar with this material, also if they can put me in touch with locating some of this stuff. As with Rick efforts, thanks for all your leg work also.

    Regards
    Geoff
