Sticky Problem Recommendations

I am looking for input how to remove plastic from my ADS 1290 II midrange dome? :scratch2:

As you can see from the photo, the stuck surface area is about the size of a penny. This plastic is very thick, so from the little bit of careful pulling, the dome/speaker is in a dangerous situation. :tears:

I did use a hair dryer for a bit, but I sense the sticky material needs to get to a pretty high temperature to loosen up, plus the fact I can't see a way of getting heat equally distributed across the dome surface area.

Any and all input is greatly appreciated.

BTW - the midrange part number is 206-0215

Thanks for the idea, but the warmth of the sun in these parts (~Cleveland, OH) won't warm this mass very much until late-August. Now that would be a great idea out west. Regards, Dean
 
Maybe turning them upsude down setting over a steaming pot of water? Perhaps even taking some acetone and lightly dabbing around the affect area. Wish you luck- those are very nice mids hope you can restore them!

Put it in an oven that you had on and have turned off, after the temperature is below 110 F or so, would be my suggestion for using heat if that might loosen the sticky stuff.

I might also be tempted to try using the rounded end of a toothpick (carefully!) in one hand between the dome and the sheet, while (gently!) pulling the edge of the sheet with the other hand. Push up at the sheet with the toothpick, don't dig or poke the dome! Maybe you have a vice you could hold the flange of the midrange with while doing this, hopefully at an angle you can see what you're doing.

We're all holding our breath- hoping for a happy outcome on this episode of Speaker 9-1-1!
 
i believe i'd stick with the hair dryer, gently pulling, and lots of patients. anything you use as far as chemicals could damage the dome. if heat doesn't work, cold might.
 
Well, the plastic has been removed by placing the speaker in front of an electric space heater for approximately one hour, then gently pulling the plastic upward.

Assuming no damage has occurred and the speaker works, this wasn't a bad resolution! It left an unsightly appearance to the dome and there are now a few small depressions, but it worked.

Be careful with those sticky domes!

Question, What is the sticky stuff? IS it a glue? What glue? What is that dome - aluminum, paper, fabric, plastic?
I have dealt alot with many types of plastics and glues. Let me know more and maybe I can help.
