a pot to do what

honestly i think its an RTV that just survived cost and performance natural selection
thats what it feels like at least

i would make a tape cylinder a box around the connector that extends past the contacts, and fill with RTV
remove tape, usually looks okay
yeah i would make a tape cylinder around the little ring by the contacts, and the fill with RTV
maybe get a fat needle syring to make sure it fills around the wires nice
RTV rocks for this kind of shit
theres also the white glue they use in amplifiers and subwoofers
the shit they pour on the caps and magnetics
i dont know what is it, because its always just called 'white glue'
the hard shit they use for fixing screws and connectors is 'yellow glue'

that said, ive never had the wires fail, its almost always the connectors
like, i guess that logic is lots of RTV between connector and board keeps the connectors from going resistive due to vibration, then up the wire to spread bend stress
and its still servicable if you use lots
hot glue, not so much
so it kind of looks like solder cup connector?

sometimes it looks like they dip the tinsel in RTC or something
er RTV
also if the tinsels are assymetric, your solution on the VC side should be small, in terms of mass, and shouldnt interfere with the spider rolls
oh this is for the wires to the terminal board? not the tinsels?
that will work, if its not a very high power speaker, hot glue too
but RTV is prob best bet
like, use more at the connector and tin it out along the wire
spreads out the stress and keeps it pretty fixed at the connector

i would trust that for the rubber cement
and tinsel probably has the highest variability in terms of prep methods
yeah rock hard is really bad for tinsel
same as solder wicking up crimped wires, its creates a localized stress point right after the glue joint
like, if hard glue is used, its usually a very small amount, and the way the tinsel bends with excursion is controlled so it does a nice arcing bend
problem is sometimes the leads will slap if left untacvked that close to the voice coil joint
rubber toughened black CA is used a lot
it would probably be used more but its relatively expensive compared to the rubber cement stuff
on the terminal side of the tinsels, heatshrink and/or RTV works well to control movement

rab: its not always the same thing, but a lot of times its a heavy rubber cement
dont remember the name of the black stuff, i should, lame
the other stuff is just two part epoxies with decent toughness
a few of the loctite hysol are flexible and flow enough to work well,
anyway, transducer manufacturing engineering is prob like 75% about figuring out the right adhesives, it effects the soft parts and symmetry so you can measure differences caused by wriong glue or fucked application
