Damn! And I thought Dreve a
Thats a

Loctite 3301. I bought a small pocket UV flash light at a home improvement store. I push the tube on the driver while having the light. Its cured enough to stop holding it after 2-3 seconds. Then i put the drivers in the cure box for 2 minutes. You have to cut it off cuz you’re sure not pulling it off the driver.

Damn! And I thought Dreve and Egger were expensive. 3301 is USD$50 for 25ml!

I've had my ONE tube for 8 months. I've made at least 40 pair and a BUNCH of prototypes. Its in a syringe with a blunt needle tip. It lasts forever and, aside for a newb mistake not recognizing it's differing viscosity, its has NEVER failed.

Alright, somebody talk to me about RAB32257. I have NEVER included it in any of my builds due to a BAD first impression when I first started in this racket. lol. I KNOW there are some avid fans in here. I know all about the Zobel, etc. I'm just sitting here looking at the measurements between RAB32257 and the Sonion2389. They're REMARKABLY similar.

I see that loctite makes some low-bloom, low fogging super glue. Which number do you use?

I use a regular one - 430 and 406. Bought a few to test them out and they're sorta similar.

Bondic, the little tube with built in LED for curing, very convenient. Holds well but will pull off if enough force is applied. It can also be re-glued if needed, if it pulls off accidentally.

It is fairly high viscosity, but still be sure to use a small amount at first, cure, then add a little more to the outside and cure again.

Any easy 2 driver builds? I got an extra pair of sonion 38d1xj00 7mi/8a, anything good to pair it with? I'm looking into making a bass boosted neutral set or a mildly v shaped with good vocals iem. Thanks!

Pair it with a 2389 or a knowles 29689 with a 4.7uf. You could also pair it with a TWFK.

38d1xj is already a dual driver, 29689 would make it triple. 30017 (dual) should work, pretty much any mid/high would work but 38d1xj will probably be too loud for most, Lpad it.

You could try to fit the other driver inside a zobel on the 38d1xj if the resistance works out. Then zobel that driver and you have pretty flat impedance.

It's easy to tune ED and CI
Either you can do zobelception or tune them seperately(will help in both)

For TWFK

That driver is one of the messy driver
The wbfk has to wired in reverse phase with FK in twfk

Actually my advice
Make two different iem
How to wire a twfk-30017 using it with a sonion 38d1xj007mi ..Please thank you
