    That is the correct tool. I always mount my dampers at the tip since I want to tune ‚by ear‘
    Someone has to invent a flexible damper tool to get around the ear canal bends :)

    858E91E2-BA9F-410D-B654-242F2CC6C076.jpeg Do you guys have any idea which one is positive and which one is negative on this driver? Straight out from westone w3 with TFWK +CI set up

    where were the input cables attached on the crossover? Can you provide a better closeup of the crossover?

    I only had phone quality pics but here they are.

    Now that the wires have been removed, not as easily. Before that, it would have been very easy. I'd try to trace the circuit out and see what tends to suggest hot from not.

    Try to get a photo of the pcb from above, in a way that the traces on the pcb can be seen clearly. Maybe a flashlight lighting the underside of the pcb could help

    I don't want to start the heated discussion, but polarity does not matter, as long as it's the same for both IEM. There are some diehards arguing that the kickdrum needs to start with a positive pressure, but I don't hear the difference. And I tried really hard.

    I will probably do that way. I am not sure which one goes which, but try left one on (-) and right one on (+).

    If the tweeter is not vented, go for reverse polarity
    Otherwise no no.
    So, never reverse a Wolfe
    You can reverse a tweeter

    I have done this, so I am telling from experience

    Does anybody know part# of these ported DTECs? Or maybe Sonion?

    Sonion 38AJ007Mi/8a X 2

    Once you get into to many builds

    A Sonion and Knowles becomes obvious

    You see the tab of soldering.

    Knowles TAB are not that great looking compared to utterly sexy BA of Sonion (well Knowles do tweeter tech better, the SWFK....but still, Sonion looks sexy and sounds sexy too)

    Knowles true back port are RAF and ED specific model

    Quite a few drivers in those shells. What are they?

    Since you're trying to avoid the bloom of CA, I stuck some tubes on some drivers from the experimental driver graveyard tonight with Bondic. Seems to work fine. It's a little amber in color, but not terrible.
