MASM 6 = BS5 + RAB
Hmm, how was the sound???
Hi,
Here is a diagram of basic crossover. I've seen preinstalled filters on Knowles GK and Bellsing 6 drivers bundle, they only have a capacitor and a resistor. So basic principle is resistor will low-pass, capacitor will high-pass. Values depend on the driver.
Smaller diameter tubing also works as a low pass filter. Higher value damper works as a low-pass.
Horn shaped end of the tube will increase high frequencies.
As for the problem you have, maybe you can simply try adding dampers through the nozzle of the IEM to reduce intrusive high-frequencies. You can also add acoustic foam between the nozzle and the eartip, sound might become more enjoyable.
I personally would not open up this 3D printed, 8 driver per side small IEM. I would assume tolerances there are so minimal you would not be able to put everything back let alone change some drivers.
I used 0805 XR5 caps (22uF seems to be the highest value available in this size), but avoid Y5V as they have bad tolerances and fluctuate with the temperature.
Caps could also be paralleled (and resistors too), this helps to get over tolerances (as these average out), I usually use x2 or even x4 resistors in parallel if I don't have required values handy.
I'd say 10 or even 20% variation in values is not an issue as zobel has minimal effect on FR and also works due to capacitors reactance, which is not changing in line with the capacitance as much.

Well I think others might be more experienced then me on this forum to answer your questions regarding different recipes. Also it all comes down to taste. I like MASM3 pro, and it’s not to hard to make. If you’d like it even easier a “simple” GV is also nice. BUT I find that listening throughout an iPhone with only apples lightning to jack adapter is almost useless. The source really matters. The MASM3 pro sounds really thin and flat through iPhone. But with balanced cable though my Fiio Q5s it’s just amazing. Bass is solid and fun and makes some of the criticism of this recipe invalid.@kmmm Curious question, of all the projects you have done which recipe would you consider suitable for listening to music (iPod, phone, etc.) and which would you think it can work well for live playing? Also if it is possible, whichever you considered, would you be able to link the specs, materials, etc., whatever you have.
Thank you
Here are my opinions on the best ones I have built so far.@kmmm Curious question, of all the projects you have done which recipe would you consider suitable for listening to music (iPod, phone, etc.) and which would you think it can work well for live playing?

Thank you
Those 50ohms are in series.Thank you @Kulgrinda, I just want to confirm when you say "low-pass" does it mean that it Filters high freqs so low freq can pass, right? As far as the project I guess I will have to figure out how to add the acoustic foam or damper. The holes of the 3D printed acoustic structure look smaller than a damper, judging by the pictures, I will have to investigate.

I also have two component silicone but it’s more expensive and kinda Messi (brand is trollfactory)What transparent material, other than Agar-agar, can I use to make the negative mold, that I can get here in the USA?
