I posted some videos previously. You can find the process of trimming them there.

I was browsing on aliexpress and saw quite a number of DIY iems, these quad BA's in particular had my interest:

I sent them a message for more details and was told they're Knowles units with a 3-way crossover; 1 high, 1 mid, 2 low units.
 
I'm tempted to get this can any of you diy buffs tell me why this could be a terrible idea? My knowledge of DIY'in these things is minimal
 
Thanks

Why do you want to spend that much on some diy iem. With that money you can buy some well know brands.

Hey guys, I've been reading this whole thread and a ton of others on different sites for the last 3 weeks and I am interested into making my own CIEM.
Now I have amassed sufficient knowledge to start but before I pour a ton of money on gear I have a BIG question.
 
I never heard BA drivers, I am aware there are different ones with different combination and endless ways to get different sound signature but what is intriguing me is the bass quality/quantity I can expect from it. There is this kind of "common opinion" that BA bass cannot rival Dynamic driver bass....
 
I am not looking for bassheads level but I want my future builds to have at least the bass quality of my current Vsonic GR07BE. The Vsonics BE have a very good bass impact that goes low with the right amount to my taste. Is it even attainable? Will they be able to move sufficient amount of air or have the same rumble?
if so What bass driver should I be looking for CI's, Sonions? should I use doubles for bass? 
 
Also i have a basic circuitry question about impedance. If I want to calculate it (with no tool just based on a design schematic) do I add the total left earpiece in parallel to the total right earpiece?
Also if anyone have an impedance calculation example of a 2way crossover or 3way crossover design that would be nice.
 
I am sure I will have other questions on the way ...

Maybe buy some shells from aliexpress (DIY Custom/universal) and some Knowles GK and GQ drivers and experiment?

That's what I have done and its a cheap way to get some decent drivers and crossover components, TWFKs, CIs, caps, resistors, etc.

Mine don't sound too bad, even experimenting with adding dual dynamics I took from some Samsung's that where hyped last year.

Can link shells if needed.
