Hi, i am new to the forum amd new to iem diy! Nice to meet you all and thank you all of you sharing your knowledge of iem. It really helps!
Dont know if anyone here still love ue11/jh 11? I love it so much but i couldn't find pair of custom made nor demo unit for sell on the internet. (second hand)
As far as I remember, someone had told me that it is not possible to "copy" the ue 11 on your own since the dual low driver ue11e/jha xxx were tailor made for ue/jh. It looks pretty much a 33aj007i/9 to me.
Then, I read a passage from a Japanese blogger who tried to build up his own ue11 and tried to draw myself a circuit according to his sharing just for experiment/learning
Dont know if anyone of u discussed about before and hopefully i didn't get anything wrong on the circuit.
If I didn't get him wrong from translation, he thinks that the replica ue 11 he made was pretty close to the original one except the bass amount.
For more info of that ue11e driver, i found it appears on the ue 18 pro (the old one) too. They were just keep reusing the same driver perhaps haha.
For that 22955 like ba they used as mid range. Some photos shows that the driver is ue low by soion (2015 i think) and some shows ci60003. It mostly like can be replaced by a standard 22955.
When it comes to the hi driver. it is a well known ue hi which similar to sonion 2389/ ed 29689.
And thats all i know for the ue11. I have also got the circuit of UE 10 (not tf10), and found it most of the iem shared similar circuit design. Dont know anyone here still remember these legacy iems. I think i will diy a ue 10 for myself first
