Wow! Amazing, can you tell some more about them, drivers, filters, crossovers, tubing, cableing, connectors, sound impressions etc? It will be helpful for all of us... :)

The basic are all in the DIY IEM documents. I am sure if you study that carefully, you can make some awesome IEM. The design are just from your creative ideas and practice.

Yes, of course, I've read this thread and the diy google doc, and that's all you need to get it done... and I'm on my way of finishing my first CI+TWFK pair.

But still it's great to hear from others who has finished up on a pair and how they did it and how it worked out. People subscribing to this thread are from all over the world and we can't get hold of the exact same materials to work with and some are newbies and some are hardcore diy'ers. Therefor I think it's great to get as much details as I can from the rest of you and your finished ciems.

Just kidding.

 

There are a few DIY guides out on web.  The key to remember is use what you can get in terms of supplies and develop a process that works based on your skills.  I've published a very doable design that sounds pretty fantastic called the Opus 3 (post #2642)  The hardest part for sure is learning to create shells, thought creating shells isn't the only place you can start.  Some people create solid IEMs and then hollow them out with a rotary tool and lots of patience.

 

HAHAH its perfect in the content side, but as a designer i felt it was too harsh to read, so I ambascially doing a book design. and printing one for my self.

To be honest I created the DIY guide as a way to study this thread and organize the content for my own self interests. Reading it and this thread should give you everything you need to start building your own.  Or, if you're wired like me, re-write/re-organize the DIY guide so you can wrap your head around the different aspects of cIEM design and there is definitely a lot to consider. Once you have a good foundation, it's time to put it to use.  Nothing takes the place like actually trying to build something and seeing the many pitfalls that need to be overcome.  But once you do, you won't make the same mistakes twice......usually.   :gs1000smile:

I am in the process of reworking my most difficult build to date. 2x CI + 3300 + WBFK

 

The Dual CI drivers take up a ridiculous amount of space and I have had to do a lot of planing just to figure out how to fit all this into the shell.

 

Currently I am trying to figure out how to make sure none of my tubes bend too far and collaps. I originally merged the CI tubing together into one tube but this joint takes up a lot of space and is rigid resulting in more extreme tubing bendis and collapses.  I have switched over to Heat Shrink tubing so that I can fit 4 tubes into the ear canal but on my most recent attempt to fit the drivers into a shell, one of the tubes collapsed again. I may need to order some #16 tubing to use on the CI's but I am so close to completing the build I hate to have to wait for another shipment.

I had the same problem the thinner tubing works great and it fits perfect on the CI nozzle. I have small ear canals and was using 3 tubes and couldn't get a triple bore in the nozzle. So I had the 3 tubes going right at the beginning of the canal portion of the shell  and made one big bore then backfilled with acrylic were all the tubes met up.

I love that idea. I will see if I can get it to work for me.

I didn't think of doing it that way because the tubes do fit, but this could really solve the problem.

Its kind of like a rigged manifold I have done many builds with 3 or 4 tubes just going to the beginning of the canal part into 1 big bore. Instead of using acrylic to seal the back portion up you can back fill it with almost anything just so sound doesnt leak out. I have used putty and pushed it in to seal it and it work fine.

Are you all using UV acrylic from Dreve, Egger? I'm looking for alternatives as I can not get these in my country.

back to the basics. IMO you learn more about acoustical tuning when working with 1 driver designs than multifold ones.

Nice work what driver is that? One of my favorite ear buds uses one driver the Final Audio AKR01.
