using weatherstripping instead of silicone dots

[brxl]

Hello all,
after years of service my Audiostatic ES300s have lost sensitivity and I refurbished them with new diaphragm and coating. I am about the last step, the silicone dots. I was wondering if I could use weatherstripping, foam with adhesive on one side, to achieve the limit of excursion, dampening and altering resonance. I would tape it to the aluminum bars and like the idea of not making a glue connection onto the diaphragm,
what are your thoughts?
Cheers

Foam use to deteriorate quickly. Also, there may be noises if the dots are not glued to the diaphragm.

Hi,

I used neopren rubber foam cut in strip shape on both stators.
Then one doesn´t need to glue them to the membrane also.
The silcone dots on the other hand only need to be applied to a single stator and the membrane.

Thanks a lot for the input. Will think about it for a day or two, then decide. I still like the idea of being able to stick it on (and possible easy retrieve) vs. gluing. I could try different amounts and positions of "Stuetzpunkte",

there will be no added damping from the foams properties that will translate into a noticeable difference.

One possible issue with the "foam" is getting exact thickness so it doesn't hold the stators farther away from diaphragm than the design wants to see, The foam needs a small amount of compression to hold diaphragm without possible Buzz. If the foam is elastic then its "spring" will have to be compressed putting force on stators.

I took the easy route...went with the silicone dots as per before.They are back together and get broken in as I type. Playing detailed on an almost scary level now, that is how I got used to the deteriorating sound year by year. The instructions per Het idee om een elektrostatische luidspreker te bouwen zat al langer in mijn hoofd. De restauratie van een bestaande electrostaat, een Audiostatic ES100, is het geworden. Niet eenvoudig, wel geslaagd. - Audio-Creative were very helpful and I tested the resonance with a real time analyzer and ping pong ball for excitation.
