LOL I couldn't resist and opened it up and messed around. I removed the band pass filters and made them a regular low pass and high pass and everything is normal

You mean normal like it's good now, or nothing has changed?

The impedance swing is normal now. The impedance is still quite low. But it sounds normal on the ZX1 and my HA5000. I think the sound got worse though The frequency response curve didn't change that much, but the sound did.

Ohh looks nice! Did you print the checkers on paper? 
 
How does the SR sound?

Would you recommend a single ED or BK for making a single BA universal?

I was thinking about making a 12 driver iem, but I’m not sure which of the drivers to use.  I was thinking about using the Knowles FH series.  I’m not sure if the RAB series is better.  I’m looking for experience.
 
Thanks!

A friend of mine gave me his spare ED30761, are they full range? Just want to play around with these and make a single ba iem of it.

  The CI30120 seems much less peaky than the CI22955. 

So I got CI-30120 spread sheet which sort of confirms my findings in fr difference.
 
PS: the spec sheet says 41 Ohms at 500Hz so I don't know why my measurement is off.

ED will be the better one.

Why not 18 drivers? More seriously though, you should try getting the right sound with less drivers. Making a 12 drivers IEM is not just stacking BA's together and hope it'll work out.

They are kinda full range. In case it doesn't work out for you, run a search in this thread about this driver. it has been discussed already and you might find a better solution...

Let me try playing around with it to see if I can get a good sound. Less peaky makes it easier for me  
 
Is there a CI with better bass than the 22955?

Well the 30120 would appear to be one.

Can you add 30120 to GK-31732-000?

why not? still depends on how you "add" it to GK

I know nothing so open to suggestions.
