I've also just picked up a Photon mono 4k for cheap too. I haven't used it yet, as I'm trying to read and learn as much about resin printing as I can before attempting anything.

It's good to know there's a few others here using the same machine, so maybe we can learn from each other.

Download an application called uv tools. Its a gamechanger.

Wire + wire to - pad (green arrows)

Otherwise your ED will be cancelling with both 3300 and CI.

If you want less bassy like I said you can wire CI in reversed phase too (orange arrows), but I would add some extra resistor on it then - 20 ohms min probably if not more and remove damping from 3300 completely or use something like 4 ohms you have here. It also depends on the amount of acoustical damping you're going to apply to either CI and/or 3300.
Both CI and 3300 in the same phase configuration will create a bass monster.

HELLO CAN SOME TELL ME HOW TO WIRE A 3300 FOR CI 3300 ED SWFK SETUP PLEASE THANK YOU

Why is it nowhere to buy Knowles TEC driver? Has anyone tried them before? I think it will be a good low/mid driver for a dual ba IEM~

IMO You may reverse CI or SWFK, I have tried it on a CI 3300 Swfk pairs. You are also need to turn those drivers very carefully, avoiding the sound to be too narrow or noisy. A lazy way to do it, You can put CI and 3330 in same tube using red or green damper will be fine and ED+SWFK Sharing same tube using Wh/Brown/Green even Red Damper depends on your crossover. You may also want to know that 3300 esp 33aj to me couldn't generate very deep in bass segment but the mid to hi freq are quite annoying. You are going to get a higher cut off point on ED like 3.3 - 1.5 uf and for swfk you can try to utlise it as a tweeter, a 0.47-0.22uf to me is comfortable. Someone might also use a higher value rez on ED/SWFK to create proper highs...


Cheers.

what are the disadvantages of making ciems that only go past the first bend?

The insertion depth is also something you need to consider during prototyping electrical and acoustic design - the deeper your CIEMs are, the lower the air volume between the IEM and eardrum, and hence the resonance frequency changes. That is why the approach to constructing universal IEMs and customs needs to be slightly different.
The more shallow fit of IEM is (eg. like you mentioned at the first bend), the volume increases hence the resonance frequency peak moves lower.

A I open thread, I have a question about designing a crossover, in this case I am using a 16 ohm dynamic driver and a BA Knowles 33518 Of 13 ohms and I need to make a two-way cut in which the dynamic driver reproduces me from 20 hz to 8 or 12 Khz and the rest is reproduced by the BA, but the question I have is if there is a separate formula for iems why do i know only from 10" speakers that they are low pass filters and high-pass, but I don't know if it works for iems that are much smaller, the calculation formula is necessary or if there is a two-way one with that type of controller that I have.

Looking for specifics on filter material.
For the 7z IEM, see this video:


I have a 7hz Timeless AE. It has similar three components:
metal screen (top)
white cloth circle screen (middle)
black foam (bottom -- inside bore hole)
[Below, I removed all three for experiments]

I have seen some aftermarket filter kits of this nozzle size (4.5-5mm).
Not sure about what the foam or cloth is. Or can those be made from source material or other kits.

I have done quite a few repairs and mods of various IEMs (Shure 535, EarSonics SM3v2 , Senn IE-8). The Earsonics and Shures take similar Knowles or Sonion filters. The Senn just has metal screen.
Yes, these can be fun and important tweaks.

Thanks!

Hi has anyone tried Siraya tech BLU to make iem shells?
it is biocompatible under ISO 10993-10 (skin safe)

Hi you all , please can you guys tell me what cam and resistor on GV-32830?
I want to buy separate driver twfk and hodvtec but i don’t know how to wire and what cap and resistor i need ?
Thank you

From what I remember - the left cap on the picture attached by you is 0.47uF, and the right cap is 5.2uF

thank you . So no need resister for woofer?

 

[saldsald]

I am trying to figure out how to implement the Sonion EST due to the very low output. Is it necessary to tame the rest of the drivers so that it is really audible? Or it is designed to sound this extremely dim?

GV has no resistor on HODVTEC
