dtr20 Posted April 16, 2016 Share Posted April 16, 2016 One of my woofers in my klf30s has a nasty rattle from a dust cover. What type of glue do you recommend to seal out? Thanks Quote Link to comment Share on other sites More sharing options...
jason str Posted April 16, 2016 Share Posted April 16, 2016 (edited) I used epoxy before with good results but they do sell glue just for driver reconing and repairs that may be a better choice. Rubber cement i hear works too but i never used it for speaker repair personally. Edited April 16, 2016 by jason str Quote Link to comment Share on other sites More sharing options...
mungkiman Posted April 16, 2016 Share Posted April 16, 2016 Not the same woofer, but I found this thread very informative: https://community.klipsch.com/index.php?/topic/140231-how-to-recone-a-k-33-woofer/ Quote Link to comment Share on other sites More sharing options...
pzannucci Posted April 16, 2016 Share Posted April 16, 2016 I have used clear adhesive caulk on a dust cap on some klf woofers in the past. Easy cleanup if you need to and totally damped due to being latex based. Just buy a good brand which should last for years. Quote Link to comment Share on other sites More sharing options...
dtr20 Posted April 16, 2016 Author Share Posted April 16, 2016 So upon further inspection, the dust cover in front is perfectly fine. There is a screen(?) thing in between the magnet and voice coil that is loose and vibrating around like crazy. I have attached a picture of a good woofer so you can know what I am talking about. Is this needed or can I just rip it out and go back to enjoying my klf30s? Thanks Quote Link to comment Share on other sites More sharing options...
Karsoncookie Posted April 17, 2016 Share Posted April 17, 2016 Without understanding specifics of the application, but generally speaking for vibration isolation, RTV Silicone caulk readily available at any lumber yard or Big Box. ??

Karsoncookie Posted April 17, 2016 Share Posted April 17, 2016 The thing is , silicone is not only well adhering, but totally more flexible than epoxy, which I think ? would be preferable. Lars Quote Link to comment Share on other sites More sharing options...

Thanks I had a rattle and there was actually some additional glue that they had bound the voice coil to the former with had broken off. There was a glob under the cap. Removed the cap and the chunk fell out. You would not hear a screen rattling loudly. If it's loud you need to remove the dust cap. Just get yourself an exacto knife and slowly work it between the dust cap and the cone (if you don't find a problem elsewhere). Quote Link to comment Share on other sites More sharing options...

I'm guessing it is a dust cover from the magnet Quote Link to comment Share on other sites More sharing options...
mustang guy Posted April 17, 2016 Share Posted April 17, 2016 The screen is to keep stuff out. It is a screen because air needs to pass to cool, and it would also affect the T/S parameters to cover it completely. If it is the spider to frame, you can repair that like this: https://community.klipsch.com/index.php?/topic/157084-voice-coil-rubbing-how-to-repair/. It is possible the spider is the cause and the sound is transmitting through the vent hole. It is also possible the screen is loose. If you decide to glue the screen, make sure you don't block the air flow. If you decide to rip the screen out, pray it isn't attached to anything important in the former.
