Hello everybody!
I newbie with these drivers, never seen them before. I got pair of EV1823M drivers, they were damaged and taken a part. So i do not have idea what kind of parts there should find inside of complete driver.
I have tryed to fix them, byed new diaphragms but not succeeded. New ones seems to be higher and cup profile is deeper than "original" when i compare with old ones.
I cant use those new diaphragms, i can trim outside edge diameter to 84mm but the cup height is the problem. (Spider to top of the cup profile)
On the box, where parts were, i found magnet and cover, i found also insulating rings like plastic. I tought that they need to install underside of diaphragm. I just start to think also, that should there found other ring as well which one needs to install on to upperside of diaphragm?
My ask is, should there found two insulating rings, both side of diaphragm spider? If yes, i undersand why cup profile seems to be too high and takes contact on to its cover.
If somebody know and will help me with this, it would be very helpfull.
Thank you guys, try to understand my english 🙂

Can you post some pictures? Hard to say what your problem is but almost sounds like you have the wrong diaphragms for them.
Of course, here is picture where you can see difference between new and old diaphragm profile.
I bought this new one from ebay. Afterm. Diaphragm Für ElectroVoice EV 1823M 8ohm | eBay and they told me, that they do not have any else diaphragm for this driver.
Old and damaged one is lower profile, somebody has trimmed outer edge to smaller diameter. But, i do not know what type it is for really.
Now, maybe somebody has solved this same problem, that i want to know about 🙂

If the profile of the diaphragm isn't the same as the original then these things are useless, the tolerance between the diaphram and the phase plug must be very precise. I suspect you got some cheap chinese knockoffs so you will have to chalk this up to a learning experience, at least you are not out a large sum.

I had a box of 1823 drivers needing diphragms a while back. No more replacement diaphragms available. SOme company sold me a couple replacements, but indeed they were too big around and didn't fit. I sold th half dozen drivers at a music flea market for a few dollars.
