    Ok. I will have to admit that I purchased a pair. Can't honestly say I noticed any difference. Someone else might have a different opinion.

    Sorry, should have stated that.

    I used them on Paradigm Studio 60 V.2 Like I said I did not see any change, but then again someone else might. For the cost give them a shot.

    I should really try and do some comparison on them and see if there is a change. I guess I must be the only one to purchase them. [​IMG]

    Do those have any kind of anti diffraction ring already? That might be why, no?

    Depends on your speakers. One shape will not work for every tweeter. The relationship of the position of the drivers is important too.

    That thing has a vertical ridge on the inside, and would actually seem like it would cause problems, rather than solve them, for how tall they are.

    You should be able to do the same thing for next to nothing:

    No this was a first time using this type of tweak.

    I've seen it done before on M&Ks and one or two other speakers though.

    My main HT speakers use the same tweeter, all of which have a little ridge for edge diffraction and the ones in my bedroom have an aluminum waveguide, and I am very happy with the way they both sound, so I haven't tried it out.

    How can I tell if my speakers have wave guides or anti diffraction set ups? What should I look for?

    If it's flat, there's no waveguide or diffraction ring. You can see here:
    [​IMG]

    the waveguide that is built into the front panel of my 902s

    You can see the "hump" on the GR T2 (aka "eyeball") tweeters used in all my GR Research speakers:

    [​IMG]

    In both cases, the tweeters are completely flush with the front face of the baffle (in the 902s case it IS the front baffle) and the guides should help minimize edge diffraction and aid dispersion.

    For what it's going to cost to try it out, even if your tweeters have waveguides, it's worth it to give it a try.

    This guy is an example of a tweeter that is basically flat

    I think I could consider mine flat as well then. How do you post a pic? I wanted to post a pic of my tweets.

    I may give this a whirl for how cheap it is.
