Any ideas for crossing 2389D and SWFK?

How's the 38AJ007 for low mids? Haven't seen a build here using it yet.

Already close them, sorry :/

Someone stepped on my BGVP VG4... So here are it's internals. It uses 2x green dampers, the 29689 and the 33518 is glued together in a 2mm ID and the 33AJ 1mm ID. Very interesting. Someone could try crossing these over and graphing to see if they match at all :p

Whats the difference between the SWFK 31736 and the 61835?

I'm asking this because I ordered this DD: https://pt.aliexpress.com/item/33031313972.html?gatewayAdapt=glo2bra&spm=a2g0o.9042311.0.0.4e53b90am8ClfE and a 2389D with creating hybrid in mind. I read somewhere here that damping too much the DDs reduce their dynamics, so I thought that L-pad +...

Have you tried an RC low pass with cap and resistor? Or you can't really do that because it will sound weird?

How did you lowpass the DDs?

So... how do you guys work with the soundlink shells? Does it need lacquer, nail polish or resin? I intend to get one but no idea on how to work with it.

Taobao seems to have a lot of very interesting drivers, but never ordered from there. Is it worth? It's way cheaper and we get more options than ali. Btw, whats the difference between the PKs? And whats Fengda or Fengru? I'm kinda new to this stuff. Also, what is 3H, 4H etc?

As @jeejack has shown

https://a.aliexpress.com/_mKuPqH5 Micropore or microporous tape. I've used tons of times with IEMs before, but works flawlessly to reduce bass duration and quantity without changing the highs response by much.

Just wow! The composite BE driver and the metal shell from NSC. I tried stock with no tuning at all but there was too much bass bleeding to mids and too much bass. Tried foam and terrible stage and no bass and texture. But microporous tape does magic. The bass now is punch and very present...
