The link you provided doesnot work, but normally they are sold in single units.

Apologies,try this one here.http://search.digikey.com/scripts/DkSearch/dksus.dll?x=0&y=0&lang=en&site=us&KeyWords=dtec   in this case the price will be at $45.51 for 1 driver?

Certainly looks like a single unit to me.

 

[MuZo2]

Yes. Though DTEC is dual driver, but its in once casing, so you will need 2 drivers. DTEC and TWFK are bit expensive.

 

[royneo]

I am planning to use them(Knowles Acoustics DTEC) as mids,any good alternatives to those drivers?

 

[MuZo2]

check page 71 for various drivers used in IEM

does anybody know where to buy a good full range dynamic driver with 32ohms??? All I see is 8ohms and a few strange looking 32ohms.  Any idea why they are encased like seen here? http://search.digikey.com/us/en/products/AST-1732MR-R/668-1140-ND/1464879

Because those are designed to be soldered directly onto a circuit board?

actually they are for alarms/buzzers hahaha.
I'm going to be doing a dual diaphragm with no crossover.  We're gonna see how this works.

Wow, this thread is fairly amazing...just spent several hours reading through all of it :3
 
So now that i'm all hyped up from reading....made a little set up and was wondering if anyone could input on some changes/ possible alterations
 
3 drivers all in parallel:
 
CI22955 +red filter
 
2015 + white filter? IF  I cant get a hold of these then ill use ->> ED Series, maybe 23147?
 
WBFK30019 +white filter + 1 microF cap

my apologies..forgot the values of the filters....been through too many pages to back track to where they were listed
 
How I think I will to make the shell:
 
1 - make impression with impression kit
 
2 - Make a silicone / epoxy mould
 
3 - Make a plaster earpiece. Make this nice and smooth
 
4- Make another mould
 
5 - Layer of Shapelock in the mould to make a shell-ish thing. At this point it should still be "open" without a faceplate. I will add parts which extrude into the area where the faceplate is meant to be and have holes to accommodate a bolted assembly with the actual faceplate. 

Question is,....with this hollow shell would i still need tubing? or could i do a funnel like thing into the canal section of the shell and call it a day?

Here is my first attempt: Sonion 2323 + Sonion 33a007
 
 
(the covers are missing)
 

 

 

 
The result was not what I was expecting!
I will build another pair with Knowles drivers (CI+ED)

Nice! Not what you were expecting in what way? That's a TF10-like setup right there; was it unexpectedly unlike a TF10?

Very impressive! Great job ebda! Did you experiment with sound tube lengths etc?

Very nice, the shells have come out very nicely. Whats wrong with the sound ?

 

[bonebrain]

Interesting shell's. What was the material that you used? It appears to have a rather rough finish to it.

Also, do the coax connectors have more weight then expected?
