Yeah, I'd trust these drivers more than the millions of unnamed drivers on Taobao, since even if after countless hours of testing you finally found an excellent driver, it'll be difficult for you to find the exact driver again next time.

I have heard the name of the taobao seller a lot
Golden voice audio

They have good dynamic drivers..what I have found out..

But for some reason, my google chrome not translating the text, which is making it hard for me to understand..

I was thinking on making something like Tralucent Audio 1plus2 in structure, but slightly more complex tuning design and simulations

I can help you translate (if its not too difficult) if you PM me the original.

Hello everyone.
I’m reading a few pages about MASM7 and I can’t find the diagram - which drivers and which crossover?
Please get a link to a post or article.

I carefully read most of the forum and found some of the information - Bellsing 10013 + RAB 32257.

But I did not find information about crossover.

There's a search bar, just search for MASM7 and read the last few posts

Therefore, he asked that I did not see information about the crossover.
Do you need to remove and install your Bellsing crossover and install your own?

Thats not the crossover but an impedance flattening circuit which goes after BS6.

You dont have to remove anything, just add it

Ok.

@Xymordos @wolkegeist

I am trying to do a triple dynamic symmetrical push pull
Do you know any small driver

6mm nearby size
And a back vent at center

Because I am not able to find one

Perhaps this one:

Or this whole shop:
https://store.taobao.com/shop/view_...9.68627484HR1nZe&user_number_id=2200714357465

Or this one, when the seller goes online (the seller seems to close the entire shop when he is away for some reason...)

Hello guys, I been reading this thread for a few days, I was hoping you guys could point me in the right direction
My wife has some serious fit issues with iems, we have bought many but they either pop out or they don't get a proper seal.
So after reading for a wile I decided to try and make and iem for her.
At first I thought the Knowles GU series would be a good start but then I read the GK series was a big step up, but after reading more and more I am wondering if it maybe better to start with a single b.a. Iem, maybe a sonion 33ap007
What do you guys recommend?
Is a single a lot easier to tune?
What single b.a. Do you guys recommend?

yes, start with the simple concept for the first time,( single ba )can use the series ed, rab, bk, other friends might be able to give a more detailed explanation

First of all

Sonion 33AP007 is not a good fullrange.

Second.

GU won't be sounding good due to its roll off in treble zone.

See, you can try

Knowles RAB/RAF
Knowles ED29689
Knowles ED26805
Knowles SR32453

For dual driver

Knowles GQ30783
Savant DIY

Etc

Thanks a lot, I guess I will keep reading, but so far I have 2 models in mind
Knowles ED29689
Rab 32063/32033
What tuning filters/tube length (if any) would you recommend?
Do these need addition elements, like cap/res or anything of that sort or can I simply solder and play?

Again thanks a lot for the advise, my wife is pretty excited, she also said thanks

In my opinion soldering skills for single driver or Knowles stacked up drivers (GQ/GK) is exactly the same - two wires and that's it. In my experience single driver setups are a bit lacking in everything.. If your choice of shell can accommodate GK, I strongly recommend it. You can choose either one or two tubes and use dampers according to your preference. I used green one since I do not like intensive high frequencies, but anything from grey to green are fine.

To make single driver sound good it takes a lot of effort - zobel cirquit, additional series resistors, horn tubing, Helmholtz resonator, etc. dhruvmeena96 can point you to the right direction. And still they are lacking in spaciousness and bass impact (limitation of the driver).

Popular option is to take ED+18 ohm res + green filter, but it sounded way too bright and sibilant for my ears.
