044 tweeter dome diaphragm replacement

[Wildrat]

044 dome diaphragm I found these on EBay. I ordered some of these a couple of weeks ago.

For JBL L112, L150, L96​

Here are a couple of pics of the domes received today. Anyone know the type of adhesive to use?

 

[Wildrat]

Tom, at SimplySpeakers could not suggest an adhesive for these. I know someone here can.

I would use the same glue as what is used for foam surrounds.

I'd use anything similar to the UHU all purpose glue.

To glue the surrounds I use white wood glue (pva glue), but I think it won't stick very well on that kind of hard dome.

 

[Wildrat]

When I did a search on Google, different sites were suggesting Gorilla glue as a good glue to use.

 

[elnaldo]

You need something sticky, able to glue plastic materials. Even contact cement should work if you set and center the dome while the glue is still wet.

Anyway, the piece won't be doing any force once installed. Check the glues you have at hand. Many glues could work. I wouldn't use an epoxy or cyanoacrylate, but general purpose glue of any kind should work.

How big are those dome VC's?

I'm lovin my Phenolic domes.

I'm lovin my Phenolic domes.

The dome is approx. 1 inch, then there is the part you glue which make for about 1.5 inches.

How are those diaphragms working out for you? I too have a set of L112's and i have a duff 044 tweeter. Mannaged a repair previously on the other unit, by resoldering the hair folical that had become dettached. This time not so lucky....

Hi,
I have a spare non-working 044 I am going to repair eventually. I have done nothing with it yet. Likewise, I know there is some kind of seal inside you have to be careful with. I don't know if it is an o-ring type of seal or something else. I've been searching for info on it. Furthermore, I may have to take it apart to find out.
Well, I gave more info than you asked for. I'll get to it soon and get back with ya, but at least I have the domes. They are inexpensive, and took about 2-3 weeks to receive.
