It can be folded, if a person is using single driver

lol
it is shell, Loushi drivers(i think some of the native Chinese cannot pronounce knowles properly....CI, TWFK), female 0.75mm connector and stuff on you bill
not a master of chinese, just know a little kanji from japanese so i was able to comprehend some letters though
by the way colsan micro as started selling electrostatic drivers

hey anybody knows why Westone uses pressure pots for their acrylic? what method are they using?
Edit: Nvm, I confused the vacuum chamber with pressure pots. Slater gave the correct explanation.

Pressure pots are an alternative to vacuum chambers when casting resins.
Both can give crystal clear, bubble free castings.
One compresses the air down with pressure so you can’t even see any bubbles. The other sucks the air out with vacuum.
This Peter Brown (dude makes some cool stuff) video explains the difference and the pros and cons of each:

Well, I don't think that they use UV curing. Know what they are using?

Peter brown uses a number of different resins. I don’t think I’ve ever seen him use UV resin though.
However, the idea is the same. When mixing any epoxy, air bubbles are introduced. After mixing but before mold pouring, it can be put in a pressure pot or vacuum chamber to eliminate the air bubbles.
Once it comes out of the chamber, the bubble free resin can then be pointed into a mold.
For UV activated resin, it then goes through the extra step of UV curing. But that step is done later, so whether it was vacuum degassed or pressure potted beforehand shouldn’t matter.

Oh okay. any idea how westone does their shells?
Slater

No, but I assume it can’t be too far off from how everybody else does it.
Hi guys!
I've been tampering with different wood faceplates lately and I came up with this pattern which I am quite fond of. Just a GK inside, but really happy with the result overall!!

They are gorgous. What is your process, do you put resin on a plate and add the wood on top? Or do you first glue the wood on the IEM and cover with resin later? How do you get them so shiney? Lacker or buffing or both?
I had to glue the wood pieces together first, then cover them with resin and glue the whole thing to the shell. Finished the whole thing with Lack 3 and voilà!

@piotrus-g @Slater @CoiL @Furco
i have this question
can we add zobel circuit and theile network to BA
i know, you gonna ask about the inductor involved in the theile network and the saturation effect plus the electromagnet effect affecting the freq of BA
i think i can shield the BA and coil, but that is not the solution
but how to avoid saturation in small coil is main issue
does anyone here has proper electrical knowledge to either guide me or make a theile network example with RC circuit layout, if it is possible
i am using Knowles ED26821. Its a fabulous driver, i think it is better to my ears compared to ED29698 and ED30262. I had to sell my pair of measuring unit in 2017 due to financial crisis so i cannot exactly tell why i like this driver. it just sounds good
My question to tagged guys is
1. if you guys know about the stuff i am talking, can you tell me how it is gonna affect the sound in IEM??
2. Where do i get driver specs
3. @piotrus-g is ED26821 technically better than those two in reproduction of spectrum or my ears are fooling me
from my speaker building experience, properly designed Zobel circuit, Theile network and Baffle diffraction compensation makes a DIY project very amazing in sound(Markaudio Alpair 7.3 frugel horn)
plus now i days i test my project with AUDIOSTAX CD
https://www.discogs.com/Various-The-Space-Sound-CD-Dummy-Head-Recording/release/7870641
It tells you about space, image and placement in accurate testing
@piotrus-g i should not post the info coming now here but i raised the CD recording above
FIBAE 1 Universal destroyed the following iem in AUDIOSTAX test and Philips Golden records plus Soundgym was easier on FIBAE 1
ETYMOTIC ER4XR(they are better in defining in low notes in space compared to SR): FIBAE 1 image or harmonics were clear by margin
Campfire Orion Cerakote : FIBAE 1 clinical definition takes the lead
JH audio LAYLA : LAYLA structures everything artificially big and hollow or sucked out guitar strings on test(I dont have LAYLA II)
Benchmark DAC 2 HGC as testbed amp and DAC
Benchmark test
Soundgym all training program
Audiostax CD
Kenshi yonezu lemon(real world test)
BTS and Blackpink
well i tried you dual CI and TWFK reverse version
@piotrus-g
This is a bad comparison.................. as two of @piotrus-g creation is what i am going to compare
one he gave to masses for free on this thread and one what he created in his lab
FIBAE 1 vs scary crossover
on blackpink this song
at time 0:11 to 0:15
exactly between 0:12 to 0:13, producers of the music added a tone which if not noticed, gives a sound of somebody slamming the door at full power
FIBAE 1: the tone was more noticeable instead of effect but the air rendered was enough to give that door feeling
Your Dual CI and TWFK scary crossover(said by some members)mk2 by @piotrus-g : This things shakes the heart, i always get startled(Literal one). i was sleepy one day, listening to this song, and it scared the crap out of me in a good way. Air rendered is amazing, but the total rumble and bass air was intense. It was like Bone conduction haptic feedback crossover-ed at 40Hz. Stage was bigger and nothing got bloated.
Tiffany young - Over my skin
FIBAE 1: there is small metal sound on left channel, dont know if it is cymbal or what, sound amazing and rendered....Way clear and crisp compared to Etymotic ER4.Actually leagues better. Perfection. Cannot explain this sound
Dual CI and TWFK scary crossover by @piotrus-g : Energy, making this left metal sound come a little in front compared to FIBAE 1 perfect placement. vocals seem more clear but not as textured as FIBAE 1
What creeps me out about FIBAE 1 is that it places things so accurate in space, that it becomes hard to fault, even with flat bass which does roll off. It places better than etymotic and fitear and feels less pressurized in ear canal. i think it is due to long horn. hmmmm.....hmmmmm.....it feels weird actually, in a great way.
second thing is
on the scary crossover
can we add a ED driver or RAB driver, because their was a specific warmth ever so slightly creeping in mids, which some may like, but not me. and this is warmth and not bloat or bleed. This creation is what i enjoyed/scared the most
cannot play doom and wolfestien anymore on both of these
one creeps me with bass and effects
other creeps me with placement of sound
both failed in making me enjoying the game......lol
1/10 to both
(This is a joke ok, i already gave my review....it is actually 9/10 to FIBAE and 9.5/10 to scary as i was able to enjoy music more)
*instead of increasing my post count for no reason, i edited it after testing*

Well the beauty of this hobby is that you can do whatever the hell you want
you can add those networks and see how they are working for you and decide if you want to continue using them. ED-26821 looks like ED-29689 with no center tap and vent instead. It will definitely be better full range driver. However if you need a low impedance tweeter 29689 would be better choice.
Thanks for review man!

i wanted to ask about thiele network(It includes a inductor)Well the beauty of this hobby is that you can do whatever the hell you want

It fixes capacitive value from driver, same as zobel circuit which flattens impedance graph on speaker
so the capacitive and and impedance graph are presented flat to graph.
theoretically, Thiele network recovers the treble which is lost due to zobel
but i read on this forum about coil getting saturated
and is knowles open on giving their driver's in detail spec like speaker driver manufacturer
