Are you using any dampers?
I use loctite on the tubes/driver connection, no issues. As for face plates, mostly five minute epoxy.

Wow. Let us know if any of them fail after some days of use.
Yes. I make the tubes as short as possible (in my ears ~12mm is enough) both ears same length though. And at the tip of the tubes I insert the dampers, to exchange after the IEM is assembled. Best sound for me is yellow on HODVTEC and red on TWFK.Are you using any dampers?
I bought a tool to stretch the opening of a tube, that way you can fit two drivers in one 2mm ID tube.How is everyone joining two or more drivers/acoustical to one tube?
Thank you. 1% sounds absolutely acceptable. I will try to follow your advice with the handling of the glue.I've gone thru at least 100 GV drivers. I've had one failure. One. That's acceptable. That very well may have been user error/abuse, but I replaced it anyway.

I use heat gun at slow speedI use a soldering iron on low to warm the tubing, then take a chopstick and push it in the tubing until it cools. I repeat the stretching if needed or for three tubes. I use glue to affix the 1.5 tubes (obviously). Then the 1.5 tubing OD fist perfectly inside that larger tubing. So it’s ok but time consuming and I worry about long term use.
I use a very soft 1mmID 2mmOD at the driver (length approx 2mm) . Then 2mmID and 3mm OD through the canal.
I have the impression it reduces some resonances if I do it like that.
Regarding glue: what to use then? I also have UHU which is better for gluing wood but worse for gluing the tube to the drivers. UHU also creates the white flume sometimes. I tried SK47 silicone glue which doesn’t create any flumes but also is not sticky enough to attach the tubes.
Well Knowles consumer paper has the impedance data. I can send that for youcan anyone advise how to accurately measure a BA driver impedance (circuit setup, measurement instruments etc?)
