How they fit?im having hard time putting 20 mm lol.

Does yellow filter affects on dB as well ? I guess ill keep 16 mm . im still looking for soft and pleasant bass sound with lots of air.

Hi guys. Someone said to make tubes for HODVTEC as long you can . Like maximum length. I usually make 16 mm ,but i can do 20 mm . Is it really gives you something? I cant find that post about that .

Hi guys . Please can any one tell me the right way of measuring a ciem with microphone? Ill show you some pictures, please tell me, which one is more accurate. On the first picture, i placed it really close . I asked, because first example gave me different frequency response from the second...

This is short video of making it. Dont pay attention on the drivers On the video . In the beginning, I was experimenting with twfk. But I end up with sonion 2389d

I mixed Egger with white resin pigment. I bought it in the Michael’s store .

Hi again, in this model ( white and wood ) i use sonion 2389D and sonion 38d1 woofer . I wired 5ohm resistor and 22 cap on one of the 2389(no center pad), and 2.2 cap on the other 2389(no center pad) . On the woofer i wired 20 ohm resister reversed . 2389d,12 mm tube with green damp at 3-4...

I will post today or tomorrow

Do You mean how i made it,or what i used ?

This is my 4 drivers that i told you guys , i just finished today:)

Uhh nice ,look at you 👍 . It got some futuristic vibe. how long you cured it under the lamp?

Yeah, i actually wanted to order them . Can get better results with E50dt ?

O nice . May be i can use Raq as a low and mid . Guys,post some pics of your iems . Im going to finish my New 4 driver setup this week with some wood face plates,and ill post it :)

Thank you I like the sound of it . Also,it was loud lil bit and i put there 5R on one of the 2389, and now i got 2khz dent lol . I like to hear details without sharpness ,also it can be my green damp. Next time ill try 3 uf for highs . Also, at this point ive tried nothing besides the...

This is my latest fr graph for the 4 drivers setup . It got sonion 38 and sonion 2389d . I reversed polarity on woofer ,because they were canceling each other . And no center pad, i liked the sound of 22 uf on one of the 2389, and 2.2 uf on other one of 2389 . All caps i ran with positive wire...

Man , thank you . Speaking of myself, i try to remember as much i can , but lots of time i just forgetting the stuff i learned here ,specially on polerity and wiring . But i got better ! Also swtnate and other people Helped with crossovers and tuning. And i still got lots of questions lol

Lol I don’t know what is leakage Whatever you say, I’m for it:)

It 38d1xj . I used 20 ohm resister on it . I like the volume of it . Also I reverse the polarity on 38 . I thought I don’t need it, but I saw something crazy happening on the graph that look like cancellation . Also ,he is my coffee time drawing ✍️ lol I want to try and see if 1 is...

thats what im about to do as well:)

Thanks man! Im really bad with math, sometimes when im confused, i just trust my ears . What if i wire one 2389 center tap, and other one normally, since ill get mids from one of 2389 ? Also , is it really matter if i put yellow damp close to driver or far from the driver(sonion 38) ...

Do you think I should wire them separately? Also,should I always run caps with positive? Because on the graph 📈 I don’t see difference. I was planning to run first 2389 with 22 uf cap and second with 2.2 or 1 uf. I spent sometime on how to wire the 2389 , because I don’t want over heat the...

yeah, i noticed that even when you cut 2 mm off, it shows big difference.

I’ve changed it. I just ran negative terminals separately with cap . Middle stays the same. Also, i do feel i need lil more mid frequencys, Since i run 2389d with sonion 38 . well, lets see .:)

O interesting:) 12 mm tube or 14 mm ? I tried 14 mm , and its seem to working. Lil bit loud

Hi guys , i just got some sonion 2389d . I think it should be wired like that right? :)
