This was NOT my goal. I purchased a "non working" driver, cheap (far as I'm concerned) as another sample for my tweeter rebuild. Well this got deeper than the other experiments. I performed all the usual checks, tests, etc. and concluded I wasn't going to get it working. Used a blade to separate the "surround" from the plate and then carefully removed the driver assembly. Since the leads are "in" the adhesive I can't verify if the break is in the adhesive, but from the looks of things there are no breaks "outside" the adhesive. So moving forward I wanted to remove the black plastic housing. These are held in place with, likely, two part epoxy. Looks a lot like varnish after it's aged many years. Since varnish can be removed with impact, due to it's brittle nature, I began tapping around the enclosure in hopes of breaking it free. Oh, part of the reason was the flange was badly distorted and I was hoping to come up with some replacement "solution", later down the road of course. Well my tapping didn't go over well. It chipped away a lot of the epoxy, but in places it cracked the housing, so I simply busted the housing off. I know, some of you are shaking your heads, others have their hands in their heads and hopefully others are LAO. I didn't have a functional tweeter to start with, so not really a big loss. But, I did learn some interesting things about the construction of these buggers. I'm attaching images of the tweeter from the original listing, don't worry not a link to eBay. Also will be a number of images of the different phases of the deconstruction. This will be my third tweeter taken apart, but NOT to this degree. The others I just removed the dome/VC assembly.
First two images are reversed, chronologically speaking. The first image is what happens when tapping breaks the face plate from the magnet assembly. Note the third image, a blob of epoxy. There were NO imperfections in the magnet or the face plate. Both were very flat and smooth. Can't understand why that blob, and a couple not visible, would be there. Also of note is the corrosion (oxidation?) on the pole piece. If this is not uncommon (near impossible to determine without taking apart), it may explain some failures or why some tweeters do not perform as well as others. I test fit the VC assembly (will post image later) and it was snug, not free play to speak of.
Anyone who has questions, please feel free to ask and I'll answer as best I can. I can't get too technical, I just don't know enough to formulate opinions on much, but will try where I can and feel comfortable doing so.
I do plan to re-assemble, and additional images will show my efforts thus far. I did all this work just this afternoon.
