Would having the tubing twisted like this cause problems? I'm trying to reduce the size as much as possible

For what it's worth, I did not see any frequency response change between a straight vs coiled 110mm long, 0.5mm ID brass tube. With sonion 3800 woofer, used as a low pass.

Do many use the blue and red wax filters on their DIEMs? If so how do you mount them, I've seen a video where a small ring holder is glued onto the end of the tube but can't find anywhere that sells them.

blue????

plus those are not wax filter but sound dampers to tune sound by adding acoustic impedance to the pipe
and control tube resonances and amount of damping by adjusting its place in the tube

you can contact bellsing directly to buy them. they quoted me 50 USD each.

mh, theyre not answering to my emails somehow... do you know other sites to buy the 6 driver ones?

Hi everyone.
Looking for a recommended build for live sound monitoring (as a singer)

not that I know of, most places stopped carrying bellsing after the lawsuit

Has anyone a good way of cleaning the paraffin wax from the negative mould. I did not use agar agar, but silicon from trollfactory for it and was already able to clean most (95%) of the wax with some water. Is it a good idea to try hot or even boiling water? I dont want to ruin the form...

 

[tomekk]

freeze it in the freezer and crush

Any ideas for crossing 2389D and SWFK?

Any ideas for crossing 2389D and SWFK?

That one would be bright AF in my opinion

I'd start with full range 2389D with red damper and 2.2uf swfk with green damper.

really? i have someone I made ciems tell me that their's work. from InEar prophile 8 tho.

I have the Cerustop bushings and the HF-4. Cerustop bushings look fantastic, but they fit into a #16 pvc receiver tube (2.16mm). The HF-4, I HAVE NO IDEA HOW TO INSTALL!!! LOLOL!!! Nick from Warnertech and I went ten rounds with those boogers to no avail. In their installation instructions they mention a "tool" to use that they neither market or sell. How every body else is installing them is anyone's guess. BTW, getting the cuff installed is no big deal. It's getting the tube through the cinch THEN plowing out the tube inside the sleeve without stripping the sleeve or breaking through the backside. I tried at least 50 times, and absolutely NOTHING made any sense. The HF-3 however, thats a different story all together. Those were pretty much a no-brainer to install. They were/ are considerably larger however. Those are probably the ones you're referencing.

Ear impressions can keep their shape for 2-3 months and often more but it depends on the quality and type of the silicone used. Some can hold their shape longer, some less. It also depends on the climate and humidity swings.

Why not use the current ciems as mold before breaking them? I would do that just plug the holes with blue tak and pour the colloid over like you would do over waxed and trimmed ear impressions. Also make yourself an extra pair of shells while at it for future work to use as molds.


Fotoplast is good for a year or more at least.

There are some silicones available now that can be used as both impression material and hearing aids. Essentially equivalent to platinum silicones in retaining form through their lifetime. However, for all things that are life, Biopor Extreme is a beast.

HI,CAN SOMEBODY HELP ME WITH WIRING A BOURNS 100 OHM TRIMMER PVG3A101C01R00 TO A BA THANKS

Can someone give me a schematic of the "new" MASM 7Z Circuit? @stephensynanta16 wrote:
"
Add 10 ohm before BZ6's zobel: Mmcx - 10ohm - zobel - BZ6
Leave RAB out of those extra resistor.
"
Considering this "default MASM 7 Circuit":

What is meant by adding a 10 Ohm resistor before the bellsing 10013? Just update the 25 Ohm resistor to 35 Ohm, or add an additional 10 Ohm resistor just before the Bellsing 10013 positive solder point like this: ?

Another question: Should I put all 3 bores of the Bellsing 10013 in one 5mm OD 3mm ID sound tube with a white and a green damper like this:

or should I go with this design from @dhruvmeena96:

"
Do BS6
TWFK grey damper@15mm (20mm lenght(2mm ID))
DTEC orange damper@10mm (20mm lenght(1mm ID))

Damper comes in small size so you can have small tube

And make RAB 30mm tube/2mm ID
Add resonator as it is
Dont change it
No damper


And use RAB32033
"

The other question: I want to use the dreve s/io fotoplast and want to make opaque white shells. Is this here fine to color the resin: https://www.ebay.com/itm/361395714212?var=630747153102&hash=item5424dcf8a4:g:7d4AAOSwEetWBJAO ?

Thank you very much

Use a multimeter and the datasheet, find two tabs that change resistance when you move the dial, wire that in series with the BA on the + wire.

Source + --> trim pot--> BA +
Source "-" --> BA -

I use the same silicon...always used hot tap water to melt the wax. Never had problems with the silicone changing shape.
