Carbon fiber IEMs: could this be the strangest idea I've ever had?

So, here's my thinking, I wana try to build a set of custom IEMs, but out of graphite, why? Because it's easy to lay up. I plan to get my ears molded, lay graphite over the thing to form a shell, vacuum bag it, and grind off the top at which point I will position as many drivers as I can in that sucker, then fill it with some dampening epoxy such that the drivers are held firmly and the shells don't resonate. But here's my only question, where do I find a tiny tiny crossover? I think I'll have to make one... and does anyone have any thoughts?

They make the drivers (transducers) you would try to fit in and they also supply crossovers.  I think you could have them connect all the drivers together with a 2 pin (female) connector for your cables to plug into.

 

You would still need to get audio tubing.

 

I would really like to try this out.  I have some extra impressing if you want to try making a shell for me.

 

Would you do the body and faceplate separately or as one peice?

why not start with a single driver iem and then maybe upgrade later

point to point SMT components.

wow, that's a good idea. the only question is how will delicate skin inside your ear react with carbon fiber. anyway, let us know about your progress.

btw, +1 to the single driver idea.

My idea would be to mount the x-over externally.
Then you can use the right components for the job.
The so-called x-overs I have seen so far seen to feature
tantalum caps to get enough capacitance in a small enough
size, and we all know tantalum don't sound very nice...
