This is the left side before closing the shell (green) and after (purple). Makes me think when i pushed the components in, some passives ended up touching

UPDATE
went in and realized one of the fullrange drivers got unhooked.
Fixed.
Blue line is CIEM form and green is UIEM (subbass roll off due to fit)

Is this actually a BA https://www.knowles.com/docs/default-source/model-downloads/sr-32453-000.pdf ? Very unconventional shape for a BA, to the point where if someone gave it to me and told me it's a DD, I'd believe it.

I think it's shaped that way so it can be a drop-in replacement for DDs.

Right from the link you posted. Yes, it's a BA

hey guys.....need some help on crossover.....

I mean I know it's made by Knowles. I know it says Balanced Armature in the spec sheet.

Is just the shape that throws me off since It seems to be one of a kind of sorts.

Claims full range but apparently another spec sheet shows quite a bit of a distortion spike at 2kHz, so I'd imagine this would make a good woofer?

Hi,
What are some options to add color to clear UV resin?
I'm using Egger clear, and Egger UV lacquer.
Maybe mixing nail polish into the liquid resin?
thanks

your best bet would be resin Obsession or Daler-Rowney Acryl ink.....they both work pretty good! i would definately would not use nail polish...

 

[johnchpark]

thanks!

so do you mix the acryl ink with the liquid resin before casting, or do you paint over the hardened resin before lacquering?

after mixing colour to resin.. let it sit for a while so the bubbles who apeared during mixing remove!! but be aware...if you wait to long the color might sit back to the bottom!
then do the casting shells...

Thank you!
Just ordered a few Daler-Rowney FW Pearlescent acryl inks.
Seems like 1 part ink to 10 part resin’s what ppl use?
Does it come out as solid color or translucent?

If your ink is an opaque, it will either not work, or take a long long time to form a shell. I have a LED box with eight LED bars in it. It's WAY too strong. I can form shells in 12 seconds with clear resin. Using black, it's 20 min, and black resin is still translucent, barely.

You will have much better luck with translucent inks than with opaque stuff.

I second this. I usually just do clear or lightly tinted shells then treat the inside of the shell for the desired effect. These purple ones were clear. I simply used metallic nail polish to cost the inside, then floated polish in water to get to the spots a brush couldn't reach.

Hello everyone, I have been trying to figure out how to do a low pass RC filter but I just couldn't even after days of trying and reading, maybe I am just dumb.
So I tried to do cutoff frequency at around 800 hz at 22955. Which I used 20 ohm connected series to the 2 pin, and then parallel 10uf.
Can someone helps pointing out my mistake?
Thank you!
