Yes and no. BA’s are incredibly inductive. Hence, not using inductors as passive components. They same can not really be said for dynamic drivers.- swtnate

For fixing tubes to drivers, I use loctite uv glue designed for medical devices. It is not cheap but lasts forever and doesnt crack over time or slip off from the drivers. For gluing drivers to the inside shell I use clear patch resin.- swtnate

Venting out of the shell will cause a considerable loss of sub frequency when using BAs. In practice, Ive never had much success. Maybe others have? I know with DD’s and Planars it can work wonders.- swtnate

Literally too many variables and not enough information to give you anything specific. We would need tube lengths, diameters, dampers, passive components, and so much more. My first bit of advice would be to keep it as is and remove all passive components and retest. Second start your mid...- swtnate

Light intensity for sure plays a role. Distance from the source can lessen the intensity in a very uncontrollable way. A 40W LED is not going to penetrate like a 80-100W LED. That being said, you are spot on about timing. I find on clears and whites, I have to dial back light intensity to...- swtnate

Here is the testing microphone and adapter I have used for years, to test out custom IEMs. Dennie Miller has been an awesome resource and extremely helpful with an question or product support issues.

@piotrus-g is spot on. You could also have a leak between the IEM and the testing microphone. That can also give you a false reading.- swtnate

Wire the whole circuit, including all components. Reverse the polarity on the Dynamic and standard connections to the armatures. Be sure ever driver in connected directly back to whatever connector you have chosen (mmcx, 2-pin, etc). Now, test polarity of the connected pads. Also, due to the...- swtnate

being a dynamic driver, you have to take into account how different they are from armatures. I would say its either a resistance issue causing the DD to not get enough signal OR when the tubes were pulled through, it got pinched. Get a component tester and test for signal at every pad.- swtnate

Also, I use 1mmID tubing with a yellow damper. The smaller sized diameter will also not require much of an l-pad as it will squash the mids and highs peak(s). I usually just use a single series resistor in place of the l-pad. The l-pad I HAVE to implement when using the sonion 33 or even the...- swtnate
