Hi all, this is my first ciem, I build with 3D koi fish. The lacquer look better than previous one, indeed must sand shell stritcly to get smooth surface after lacquer.

Do you all have experience with black color? I mix with uv glue. But after UV, its still not dry completely inside although outside is hard.

Looks great! Keep on building.

Oh damn that fish looks super cool, how did you do it?

I got the litz wires from soundlink. It's already tinned, however I want to cut it into shorter wires for my crossovers so that the cable/wire management will be more manageable.

Alright, then just do as I said, will work fine

Just place a fish in face plate, bro.: )

I always put flux on the litz wire before tinning, no other prep, works great. Scrape some flux up with a razor blade and put into the wire, then solder.

Will there be a difference if I use 2-3 wires from the pin to 1 pad of the driver? Say 3 wires from the pin to CI's positive connection? Or it's just stupid?

Theoretically, you'll divide the wire's resistance into 3. But there would be no difference than making the build harder.

Details on the switchable crossover. Trimpot lets me boost bass more, wasn't sure how far I could/should take it, so I'll have to tweak it and see.

Switch position 01 sounds best so far, no bass boost, bigger low pass filter to cut midbass.

Good treble presence from 10-20k, bass is thick but clean, so good soundstage. Pretty happy with these.

I can try to justify that circuit design after the fact, but honestly just playing with with breadboard, that got me the curve(s) I was looking for. Full range mid and high passed tweeter, in parallel with a resistor (variable with switch and trim pot) then a low passed woofer in series (more caps switched in for lower frequency low pass.)

1) First way I found to get a low pass working without affecting other drivers
2) The resistor in parallel with mid/high limits the impedance spikes (edit: and makes it very easy to attenuate the low driver -smaller resistance here = more volume on the low end.)
3) It still has good instrument separation and clarity, which I did not expect in series with the woofer, but go figure, it works pretty well.
4) I don't know exactly how the big guys use switches to tweak the sound, but usually it is very small changes. I wanted something pretty noticeable, so again, it just seems to work.

My fish is bigger than itsfit , so difficult to put it in face plate

Is there now any place on the internet to buy a Sonion E50D? E50DA005 exactly?
