Hey guys!
I've been reading the thread for a couple years, built(and rebuilt a couple times ) my own custom 2-driver IEMS and have been using them for more than a year already, mostly on-stage
.
Some time ago I got the insides of UE11 but they're not soldered together and as I have no experience with crossovers I wanted to ask if anybody has a diagram for UE11?
what I have is:
- Driver that says "UE 0832 UElow" attached to a dual driver "UE11e 0744" (I think these are Mid + Sub/Low respectively, but I got confused by "UElow" written on what I think is a mid driver) x 2
- Driver that says "UE 0837 UEhi" x 2
- thin film resistors "10R0" 10 ohms each I guess x 2
- SMD capacitors "155 35k" seem to be 155 pF if I'm not mistaken x 2
The other problem is that I can't figure out polarity of the drivers as there's no schematics for them at least I wasn't able to find any info about those. What I figured out was that dual "UE11e 0744" driver seems to be the same as Sonion 33AJ007i/9 in size and appearance
pictures are here:

Ue11 uses a Knowles CI-60003, Sonion 3300 (probably 33AJ007i/9 ), Sonion 2300 (probably 2389)
according to this pics the 2389 is wired half coil,
look at this one
unfortunately I don't have time right now to completely figure out the all the connections but from here you should be good to go. yellow and red wires are usually the positive ones...the resistor in series to the CI, and the cap is for the 2389 half coil
polarity for the Sonion drivers can be found here
http://www.head-fi.org/t/430688/home-made-iems/4380#post_12321839
Pay attention that the 33AJ007i/9 you have is already wired in series for both parts (this is a double ba)
can you post a clear picture of the cap values you have? cause it seems like a 1.5uf from what you say...also can you say what color are the dampers to which drivers (one is green from what I am able to see)?

I have a question for anyone that had/have a UE900 or UE700.
Those iems use a TWFK-60232
this a a TWFK with a cap attached to it.
if the ue700 are just using this driver with no additional components then the impedance should be ~40ohms according to some sites or 49ohms according to this graph. which is close to the impedance of the TWFK-30017 rated at 43ohms...
measurements of them from here http://en.goldenears.net/index.php?document_srl=2072&mid=GR_Earphones&sort_index=readed_count&order_type=desc
The ue700 have a green damper to them.
Anyone knows the value for the cap? I think Shilo stated it is 22uf. I just want to be sure
Also are those a TWFK the same as the old TWFK-30017 with a cap on them?

hi all,
my result is so bad with derve fotopast S hard, it's not so clear like it should to be.What am i wrong with it ? or Should i use a sandpaper to make it shine ?

how to make the silicon without air bubble or less bubble ,could you please give me an advice .

thank you, sir! great info.
dual bass driver and mids use 1 tube and there's a green damper there
tweeter uses a white one

you can use a vacuum pump for that
you can use a vacuum pump for that
pressure pot rather than vacuum chamber.

The ue900 uses a 0.82 uf cap on the wbfk side of the twfk, the 22uf cap I talked about is used with the GK driver.
I have a few twfk drivers from ue900 and I'll look at them when I get home and see if I can run some tests. I would just check to see which side you connected to, if you ran positive to the FK positive pad then it would be wired correctly like in the ue900. I removed the cap and tested which is where I got 0.82uf (also most favored cap for the twfk according to knowles). I think it is twfk 30017

thanks for the answer So,how about vacuum hand pump is that work too ?

it shou
it should work I guess give it a try and let us know I'm also experiencing some issues with damn bubbles
or maybe this thing could help, what do you think guys? will it be enough power?

Awesome, if this is the case then I think this kind of twfk is used as parts of the "big shot" 10 BA drivers CIEM

I'm planning my next set of IEMs and I wanted to emulate the setup on the Noble Savants so I got myself a pair of ED-30761s from AliExpress. The issue is that the drivers don't have ports on them! They have small slits where (presumably) the sound comes out but no cylindrical nozzles to connect tubing to.
Any idea what I can do with these?
Here's where they came from.

You can cut your tubes and glue it over the top and side of the drivers.
I think there was the tear down video of the savants and showed how Noble did it.
