    The coating must be less than 0.2 gram.

    I couldn't find any different weight for 3 2425 dias and 1 275ND dia.

    JBL says the 275 dias was lighter.

    What were using measuring with? The kitchen scales?

    D8R275ND is EXACTLY D8R2425 with Aquaplas. But they need to make a bit mystery.

    They certainly didn't have the same FR when I measured them.

    I need to get back to working with those. There's way TOO much mystery here....

    There are too many variables to see the weight difference on the mounted diaphrams installed into the ring holders. You need just the diaphrams to see the weight difference.

    Rob has a good point.

    2nd pic D8R2425 in same core

    Lower Fs for 275 means slightly more weight

    the plot thickens

    Hey Guy's,

    I have 4 pairs of dia's to Aquaplas. Judging from the post's Pehaps I'll should wait on it until a verdict has been reached.
    The main reason for my ergency whas the NEW SCREETHCY Ti dia in the 2425. The mids seem a great deal smoother since some clever cloggs suggested using the L-pads. - 1db sounds much,much better. Thanks for the Photo Ian.

    Rich, Keen, but new to this

    Aquaplas, Antivibe & BaryVibro

    The BaryVibro certainly looks like aquaplas in the description, and in the application. the picture they have of a post treatment sure looks like aquaplas.

    I'll email them, and get samples if they sample. meanwhile I've got the a sample of the thicker trowlable coating coming, which I think can be high speed mixed down into a thinner coating with the proper rheology by adding water carefully, and perhaps a rheology modifier, like PUR based associative thickener.

    Time will tell, but if it can be made down to a usable viscosity, then anyone wiith a small mixer (drill and a mix blade) could get a sample and follow instructions to make it; since the rheology modifier samples go a very long way (as they are used at a very small amount added to get thickening effect).

    It might be asier than we all thought

    I just talked d with Betsy at Blanchard about the antivibe (formerly Aquaplas).
    She says there's only one version, it comes as a thick paste with complete technical instructions for use as a spray-able version or a trowl-able version.

    Saty tuned for updates.

    If you call and ask for samples they will send 1 gallon, however I didn't mention aquaplas, and I expressed interest in coating acoustic materials onto a web.
