    No idea what that is. LOL.

    What's a RAB-P?

    if I'm not mistaken and iirc, this is what they did with the QDC Gemini, single switch. Either resistor in series with dual CI or by pass the resistor so the dual CI is directly connected to the source.

    probably something more like this. Or other configs. you can wire them up in different series/parallel configs. In your diagram, when you turn off all of the switches, the driver wouldn't be connected to the signal source.

    I use the 365nm one. I don't have problems curing dark colors with this one. Tho I use a different one for my clears because this is crazy powerful. What I did with my dentist's light pen is replaced the LED with a 365nm 3W SMD UV LED. That might work for you.

    What do you mean? I'd use it for better layout for engraving in my laser. Would also prefer to laser out the faceplate shape from my faceplate blanks. If you're thinking that I would send them to be printed by other shops, nah, I print my stuff in-house. :D

    Hey guys, aside from Fusion 360, any other way to create a PDF for the faceplate from an STL?

    cramming it inside a really small shell is kind of difficult tho. I used to do that a whole bunch but after lifting the pads (both from the cap/resistor and the BA themselves) I moved to making a wiring harness. Never did a parallel to the driver with caps tho. Wouldn't that act like a LPF?

    you have to check your settings bro. I think 8 hrs is a bit much. 5 hrs max for me. That would depend on how I orient my shells and how high they are.

    This would depend on your printer, sadly. You have to know which works for you the best. Printing without failures + printing at the shortest time. Sometimes, there are even batches of resin that you have to increase exposure time by a second or two.

    Great! How did you manage to create the chamber/driver holder? Is it from a hollow shell?

    Yup, there's even a 24 drive monstrosity with a crossoverless design! never liked anything from CA personally. Especially the OG Andromeda. It sounds weird and unnatural to me. it's in page 85. Download it and change the file name extension from .txt to .stl.

    With that response, do you find it necessary to apply a high pass? Looks like that can do without one and can just be controlled with resistors and dampers alone.

    Exactly my point. It's hard to compare just by data sheet alone.

    What are these graphs? Bottom SWFK? Problem with Knowles' graphs. Sometimes they aren't standardized. So comparing them them via spec sheets is not comparing them side by side equally. Best way is to measure them side by side from the same jig.

    Anyone can compare the e50 to swfk? Graphs would be great.

    Home-Made IEMs

    Yup! That's mine! How do you like them? Isn't it too small for your builds? I'll try too look for the other stuff I made. Here's also one I made. Lemme know if you guys want it.

    I do soldering to the socket, and in between wires then attached to the shell. I stopped soldering them directly to the driver.

    I have modeled some shells for different folks here. I can share em if you'd like.

    Already posted above. there's a slit on one side so it can only go one way.

    3 of them are positive, 1 gnd.

    Japanese DIYers integrate a holder for connectors when they 3D print their shell. You can just cut a slit at the shell and add resin around it and cure it. That will hold the connector in place.
