TL : DR - Please recommend the best sounding driver setup that requires a minimal amount of soldering/setup. My focus is primarily the design/printing side of things but I'd still like them to sound good.

So I just got my impressions with the goal to build my own IEMs. I'm handy with a soldering iron but know next to nothing about driver/crossover science. I currently listen on Tin T2s with custom diy molded tips. To me, the soundstage is very nice (I consistently hear something off to the side in the distance and turn to see what it was only to realize it was something in what's coming through the audio) and I'm hoping to meet or exceed that with my DIEMs. What driver setup should I use? I've found that the Tin T2s seem kind of hard to drive with a FIIO BTR3K and the FIIO UTWS1's. I seem to have to nearly max out the volume to comfortably hear the audio if I'm not in a relatively quiet environment. I'd love for my diy's to be easier to drive so I can use those BT receivers if possible.

I've done some reading but I'm still unclear on what to use and how to connect things (series/parallel etc) so I'd like to find something easy(ish) to install or some write-up of what drivers to use and how to connect them.

I know this information exists somewhere in the 837 pages here but I'd prefer to get these done sooner rather than later after spending the next year reading through all the posts.

Thank you for taking pity on a first time poster here and dropping your knowledge on me!

I don't see the point of investing in electrostatic for DIY without a background in reverse engineering and a lot of experience in armatures. 120$ for pair EST is a package of drivers for the top of the line DIY project.

38D1XJ007Mi is a bass crushing, rumble beast. The best woofer without low pass filter problems.
I was told the ESTs are not that hard to implement as they need no damping, what seems hard is rather attenuating the other drivers for their higher efficiency

I'm trying to facilitate a group buy of the Sonion 26-E25WT02 for this, they are pretty much plug and play it seems and already crossed over. Only available directly from Sonion though, MOQ is 25 units.

You could consider a single balanced armature driver, this literally requires a wire on the + and the - :D

Sonion 2354 is a suggestion for a full-range driver

How close are you to fulfilling that minimum?
So far no one was interested lmao but I only posted it in this thread yesterday. I'll take 6 myself

Finally got around to posting the new iem I've made - another one based on the UERM. Wanted to improve the treble extension and flatten the impedance while keeping a similar FR. Uses 6 drivers, 2x Mid-Low, 2x High, 2x Super-high. Sounds very flat but the bass doesn't sound as anemic as it looks - bass quantity feels quite decent.

Made with abalone shells and nail art products lol

My god! Those look really hard to make! Are those dual CI and ED? How does it sound? Faceplate looks amazing!!

The faceplate really nice, but the shell transparent look not good in this one because inside look quite jumble. Thanks for sharing.

@Xymordos that's a tight fit, nice work. Are those 1206 size caps? Do they have advantages over 0805 size? And can you give a basic circuit description (what is in series/parallel, zobel on anything?)
