Now I need some help...   I'm ready to hook it all up with internal wires. I got the CI+TWFK and can't figure out where to solder which cable, how do I know which solder pads are +/- or doesn't it matter? I can't find any schematic at knowles site describing anything. I did find som scheme...

  It's awesome to see all finished works, looked at a couple yesterday and was thinking that a great idea for all aspiring pupils of this thread would be to share as much as possible of the builds. Such as:   * Pictures * Mold/Shell materials * Drivers * Filters/caps/res. * Tubing *...

What kind of tubing do you use? I seem to have some trouble finding any specific for audio use. Is it a 2mm inner dia. to be able to fit any damper inside I should be looking for? Perhaps I can get hold of a PVC 2.0/2.7mm (id/od) isolationtube, will it do?

I'm not sure, but doesn't all plastics bond with acrylic more or less. Perhaps I'll have to use some bonding between, or some superglue.   My first finished shells are done, some final finishing still to be done but overall I'm really pleased. Great glossy shine, not totally transparent but...

Well it seems it doesn't really matter how it looks... Since I can't effing solder!! 

They look great but still there's problem with soldering on the socket pins. If they were hollow there would be no problem but now I have to solder the wire onto the pin (which doesn't seem correct?) and then put on some shrinking sleeve. 

I received my connectors from Null Audio yesterday, tiny little things :) They fit prefectly together, with a little snap and it seems to grip tight.   But I'm not really sure how to proceed with the pins inside the shell. It's two solid pins, am I just suppose to solder the wires straight on...

How do you compare MMCX vs 2-pin, except for the obvious pricedifference. Which ones do you prefer? Do the MMCx attach to the socket enough?

  Thanks, I actually found these as well yesterday. But first I'll try the connectors/sockets ordered from Null Audio, which was shipped today :)    Next problem is the acoustic tubes, I don't really know where I can get them. Does Microsonic ship to Europe? I also looked at Audiotronics.it...

But if I need to find some nice 2 pin connectors male/female at Mouser, how do I filter it out... There are 12.000 connectors and I don't know what to search for?

  I ordered sockets and pins from null-audio, and you can choose from 3 different variants   http://www.null-audio.com/collections/diy-parts/products/ciem-diy-sockets    Only ordered last week so I haven't received any yet.

+1 Looking at clear UV gel for nails as an alternative to Fotoplast, anyone who has any experience with this?

I'm not that far into this project yet but thought it best checking about this already... When soldering the cables to the drivers soldering pad, do you think it will work to use a professional desktop laserwelder? We have a unit at work, I can't work it on my own but somebody will be able to...

Ok, plaster I have plenty and I think I can get some agar-agar as well, will try it out.   Right now I'm doing a new negative mold in gelatine (food-grade) instead, last time I used it for the acrylic mix it came out very nice and smooth.

  Wow, great info! Do you know what material is used for the negative mold, since it has to be preheated. Don't know if it will work with silicone? Then you just let it set a bit and then pour out the remaining acrylic mix, am I right (like they do with uv treated shells)?
