Do you mean universal or customs? If you want universal you might me able to get some shure shells from ebay seller. He also sells cables and plugs.

No. The last thing you want is ear irritation. You should look for bio- or medical-grade materials.

Yeah, I know about the Shure shells; that's not a lot of room, so you can't experiment with anything greater than 2 or 3 BAs... the ASG generic shell can probably stuff six drivers in...

There is lot of info on BA driver mfg, is there any similar info for Dynamic once used in iem?

 

[piotrus-g]

actually no, but maybe I didnt go into reseach deeply either
I know that Knowles makes some DD but besides one 16x3mm none of them seem to be interesting for earphone application. Yet 16mm OD is def. not for custom IEMs.
 
Fosetx maybe? you could try mouser but there's probably lots of DD

Friedrichs, check ou Solarez MSDS (= material safety data sheet) section: http://www.solarez.com/msds.html. The monomers (these are the plastic polymer building blocks) such as styrene, other epoxides or acrylates which are used in mixtures such as those of Solarez can be allergenic, toxic or carcinogenic. They are fine for outdoor applications where residual monomer usually do no harm without contact to skin. But nothing you would want in your ear canal for the duration of a symphony. 
 
-> dont use materials in contact with skin that are explicitly designed for this purpose.

Would anyone happen to have a link to a supplier that would sell to individuals?  I have gone through this thread but have not necessarily found a good link for UV curable bio/medical grade material?
 
thanks

Loctite 3321 AFAIR

If I were to do a quint, with 1-CI and 2-TWFK, should I bother with a crossover, or do I not need one?

LOL. Yes you need one and actually pretty complicated one. You'd need 3way 2nd order crossover
 

 

[alexlsn]

thanks, my only problem right now then is finding small enough inductors...

 

[bonebrain]

Can you not wire the two sections of the TWFK independently as well so you could do a fifth order such that each section of the TWFK has a distinct section of response?

I am wondering about how important venting for IEMs is. I realize some earplugs are vented, some not. Whats the rationale for this?
