    Question foam guard sealer

    so I'm reading this article ...

    http://www.audioholics.com/tweaks/do...imply-speakers

    and it says "Use a foam guard sealer on the new surrounds. This increases the surround life expectancy while also tightening up the response a bit to actually help improve the driver performance over its original condition."

    never heard of this stuff .....anyone ??

    Snake oil. Does it grow hair too? If so, I'm interested. Bet their next product is speaker wire insulation protectant.

    Seems unnecessary to me: as mentioned in the article, new surrounds are
    often made of material with a longer expected lifetime... also, one person's
    "tightened up response" is another person's "changed the design even further
    than the replacement surround material difference" (unlikely for a "foam sealer"
    to compensate for a loose spider).

    Doesn't bother me that someone might want to have it done or perceive
    some value in doing so, but if I were buying something, I'd want to know
    if this was done, just like I would want to know if a cone had been
    "weatherized"... I sort of see this "sealer" service in the same vein... there
    may well be legitimate reasons for having it done, they're just outside of my
    personal intended use and need.

    well , this super stuff is guaranteed 7 years , which is less than I expect from normal foams

    Editorial Note on Foam Surrounds:
    Simply Speakers utilizes a poly-ether based foam rubber material for their refoaming kits. This has a much longer life expectancy than the original foam used by the manufacturer which was a polyester based material. Simply Speakers also warranties their refoaming on home audio for 7 years and automotive for 1 year.


    then their picture "with sealer applied" certainly looks like standard foam glue ? and it may appear that the
    foam is now on the fronts ?

    and if you look at the bill that the writer is so proud of: $30 for 2 new caps & foam sealer.

    - A few years back a local ( longtime ) reconer here in T.O. showed me a plastic-bottle of foam "guard/sealer" .
    - So the stuff does exist . It was to be brushed on after the normal refoam procedure . He couldn't remember where he had got it from (ie; it wasn't in the typical Waldom tin-can ) . He speculated it was from EV maybe .
    - Anecdotally; my cousin has a pair of Tannoy HPD315s ( coaxial twelve-inchers / circa 1977 ) whose foam surrounds should have disappeared by now / but they haven't / leading me to believe his are treated with something similar.

    >< cheers

    Call me Snake.

    What is snake oil? LOL

    So that’s what JBL Control 1 proIII looks like up close. The size of that tweeter is larger than the regular control 1.

    Is that the same tweeter as used in the control 5? It sure looks like it.

    Okay so I’m into rubber then. I just want my JBL to be kinky that’s all.

    That didn’t take long to read though. I don’t have issues with cloth ribbon it’s been a good long lasting and durable on the 2240.
