Maybe one with lower viscosityshould be better. (Fotoplast LV is Low Viscosity btw).
also temperatures play a role since when colder it's more viscous.
what about pro3dure stuff? they should have a resin for dlp applications iirc. maybe you can acquire it
Dreve makes resin specific for DLP printers, problem is I haven't found a place where we "mortals" can purchase it...

Yes they just sell to companys
Lol man, you'll get terrible readings with this, to be honest. You are trying to replicate a IEC711. This what you need to know: a 1/2 in tube around the Dayton mic. You can expand your mics diameter with tape, as the tube is too large for the mic. Then, make your tube 15.75mm long. This is the essence of a 711. Make it taper down to say, 1/3, maybe 1/4 of an inch, and then add a second tube for inserting your drivers. The taper must be at 90 degrees, and the whole thing must be sealed.
15.75mm or cm ? Can you show me pictures of that constuction ?Lol man, you'll get terrible readings with this, to be honest. You are trying to replicate a IEC711.

Wow thanksThe taper is approximate. It is symmetrical. 15.75mm is correct, not .7527.

Indeed, we mortals lol.Dreve makes resin specific for DLP printers, problem is I haven't found a place where we "mortals" can purchase it...

I feel your pain.
there is that stuff https://www.imakr.com/pro3dure-resins/pro3dure-gr-10-guide#/288-wavelength-405nm
https://www.protoproducts.com/store/Pro3dure-GR-10-Clear-1-Liter-p51396484
they also have those https://www.pro3dure.com/en/products/audiology/polymers/3d-print-resins/

noob here, what happens is you block the vents on a BA driver?its differ quite a bit. 32033 which is vented, will add quite some to the bass, has slower bass decay, but sometime also creep into the lower mid (i dont really like it). And due to it's bassy nature, it doesnt help much on treble area. it will have warmer vocal.
32063 is the opposite of 32033.
the build is depend on your taste:
32033 for extra bass & dynamic-like slower bass decay (will pull it toward warm)
32257 is the middleground (i prefer this) (less warm)
32036 wont add the bass (might be bright? i havent tried)
why everyone tends to use 32033? Could it be because of me spam posting my build which use 32033, LOL.
I don't recomend 32033 either. Go buy 32257 instead, its flexible, if u need more bass, just remove the vent cloth. 32033 is 32257 without vent cloth.
Then you have less bass ba drivers dont move air whit a vent it does move a little bit air and simulates kinda dd bassnoob here, what happens is you block the vents on a BA driver?

Guys where you buy your capacitors, i can't find a 5µF anywhere, albeit mouser or digikey...
Two 10uF in series is 5uF.Guys where you buy your capacitors, i can't find a 5µF anywhere, albeit mouser or digikey...
Caps have very bad tolerances, if you have a multimeter that can measure capacitance to some accuracy (1% is good) then just buy a few and look for some that come close to your values.

Thank you man! It seems i will finish all of this with a 10ohm28ohm10µF10µF sausage xDTwo 10uF in series is 5uF.

Should be good now haha

less bass, as @Cevisi said.noob here, what happens is you block the vents on a BA driver?
Also on some case, u'll get some kind of distortion/weird resonance as a bonus, lol.
try to give the vent some space to breathe.
Here we go i take impressions by an audiologist a few minutes ago she asked me for what i need them i said i want to build ciems by my self she was pretty interestet and gave me an tutorial she was laughing all the time from where i know dreve and knowles she told me how to make the shells and yes we all do it right like an profesional she was astound that i know how to do it but we make one fault she said there is acryl from dreve that is light harding but not transculent and it will make a 1.5ml tickness shell from it self even if you put it for and hour under a uv light
She said they are ready to go i pre cut them just dont forget to dip them in wax 2 times before you make the mould
Now iam try to build my first shell

They look very good!
