Its hot and cold.oh wow, that I didn't know of, that BAs are small portion of their company. Just wondering to if there's a place that the RDI can be purchased in a not so huge quantities? If not, what good dual woofers can match it?
I thought you had a good relationship with Seltech?

I mean, its $45 per driver. You can get two 3800’s with ferrofluid , shipped for less than that.

What's the basic tools/equipment that you need to start?

Hello,
I've managed to create my own CIEMs from GV 32830, can't seem to find the way to share picture, but I guess you've seen a ton of those
I would like to try to add a tweeter with a crossover. I've checked a lot of in these forums, but could find any answer on which tweeter I should buy and how my crossover circuit should look like. Anyone could help on this? Would be really grateful
Most of the information I found here, but not sure if it's correct, that I should use this tweeter:
Knowles TWFK, but which one? Will this one fit for me? TWFK-30017-000
Do I need to add woofer CI-22955-000 or just taking the tape of from GV will be enough?
Thanks

Hard to find anything from Sonion that mentions ferrofluid, could you let me know which drivers / what indicates ferrofluid in the part#?

Do you have any idea for fixing vocal backimg?
I believe it's the 3800 series 38d1xj007mi that has a ferrofluid

would a consumer dlp printer like the mars 4 dlp suffice for printing tubing (like 1mm id 2mm od)? if not, are there any consumer printers that are up to this task? from what ive read dlp printers should have less problems with printing small holes

also if any of you have experience with printing tubes i would like to hear as well.
Hi guys , i forgot if you asked you guy if Sonion 38D1XJ007Mi and twfk 30017 build it good idea ? Should i wire reverse polarity on woofer or on twfk ? I should write this stuff , i always forget 
Hi everyone,
I started the hobby three years ago. I want to go deeper yet the diminishing return and the price is holding me back. Im still a student so I dont have the capability to buy really expensive iem. So I guess I'll start to make my own iem and in return customize my frequency response. I don't know much of building one but I believe I have enough skills working with resin and some circuits.
I plan to make a three driver setup with three way crossover, yet studying signal filtering, cause me confusion on why do everyone only use simple circuits.
Are these diagrams overkill? Or there are something Im missing out, like the drivers' resistance simplify these diagrams that makes them insignificant. Wouldn't there be any signal noise if these kinds of circuits were not used?
The diagrams in the first img are just my sketched diagram of what I think might be a three-way crossover. Is this applicable for an iem or is it just exclusive for speakers?

Hey.
My first time working with the 38d1xj007mi/8a. Just want to make sure.. I shorten the + with the second + and the same with the -, right?
And what is the method to shorten the pads, with the same wires that are used for wiring?
Another thing, I measured the driver with a 1mm ID tube about 10mm long. The response graph is very different from the one that sonion presents.. I measured an increase of about 10db between 20 and 100 and a decay only after the 1k (in datasheet a decay between 100 and 1k of 25db is shown..)

It works well. I found it easier with the wbfk and fk drivers being separated, to achieve the proper eq.Hi guys , i forgot if you asked you guy if Sonion 38D1XJ007Mi and twfk 30017 build it good idea ? Should i wire reverse polarity on woofer or on twfk ? I should write this stuff , i always forget
I have to order some wbfk .
I went for 4.7r lpad and 4.7r on series on 38D1, and it’s became quiet . Im not sure if i like that lol . Also i put 22 cap on twfk .
I will post drawings tonight
