    Try reducing the overall spl of 31736 i suppose? Try a lower capacitor to cross

    I see! Since i have been seeing ue doing series inductor and series resistance, so I have been wondering that.

    What does series inductor does? Never used inductor but it seems that quite some big companies use them. And with inductor as rc low pass it does not add resistance.

    Thank you for the swift reply! I see, I will try it out tomorrow as its getting late here. Another question, for dual drivers like 2389d, do i only need to solder one terminal of a ba or do i have to solder both of them? What about drivers like 30017? Thank you!

    Thank you for the reply! What do you mean by control resist it? I tried bigger series capacitor, but it has a lot of 7 to 8k, and it makes it really sharp, i only wants the treble after 10k. Also I just realized that i forgot to include the picture of the graph! Silly me.

    Hello everyone, I am trying to cross 1audio 31736 at 10khz, i have tried many series capacitor and the best I could get is with 0.11uf which gives me this graph, and the SPL is crazy low. However, what I would like is to only have frequency above 10k,, is there anyway I could do this? Would love...

    Thank you! I should try to get an impedance tool.

    I see! Thank you for the reply! I tried adding rc filter to my mid high drivers just to test it out and see if it changes from different amp just to experiment(I dont have the tool to measure impedance yet), but its only the low end that changes. This is becoming a problem as it sounded bright...

    Hello guys! I am facing this problem frequency changes on different amp. I have been using my Ifi nano BL iematch which is for sensitive iem and headphone as an output to my iem and to measure. Recently I have tried using the direct output and other amp and noticed a 2-3db decreases on the low...

    Hello everyone, anyone know where I can find sonion e25 series of super tweeter? I searched everywhere but I couldn't find one, the only one on taobao has only a stock. Reason I am looking for it is because it is arguably best super tweeter(?), and i really like sonion's sound when compared to...

    I see! Besides phase cancellation, what else does a good phase alignment do? I see big company like JH always make sure their phase alignments are close to perfect, even to the point of not caring much about the tube resonance(tweeter having 2 times the length of woofer).

    What does this means? I am confused. Does that means that using a longer tube for bass driver shouldn't affect the phase?

    I am using 1.2mm for 22955, and a short 2mm in the middle for the damper to sit on. I was thinking of even longer tube (3 cm) but it mess up the phase 😕

    Oh! I havent really tried using L pad, have been reducing spl with only resistor but it somehow flattens the low which is not a good thing in my case. I shall look into it!
