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. :applaud:
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 foamsQuote:

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.
after
- 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 :)

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.
Why can’t they just use rubber its less depressing than foam.Quote:
