    Hi Gabby, I want to thank you for all the information that you carefully selected to pass for your viewers. I am currently planning to build my first hi-fi system. The journey is absolutely amazing and rewarding. I was thinking to buy the speaker kit from GR-research and build my own amp, dac, and streamer. I am learning so much from you, as I;m a student and i can't afford to pay thousands on each component.

      Hi Gabby, thanks alot for this huge information. I'm working on a project and I'll like to partner with your company. I'll give you details of the kind of specification of speakers and sub woofers I'll be needing crossover for. Please can I get you email address or a phone contact so we could talk more .

    I have a pair of Pioneer CS-99A with a very complicatedly designed crossover, however its bass is weak, while the mid to high are too hard. I also have another a pair Technics SB_X500A with a much simpler crossover, but its bass is much stronger than the CS-99A, and its mid to high are very much warm and comfort. Its bass is even stronger than the Pioneer HPM-100.

    Good work! To decrease size of an inductor we can use ferrite road.The size of a coil without a road is quite big.

    Hi Gabby, We love you speaker design, Thank You!
    - So exciting that you are documenting your build to help others , so few people show these kinds of examples to help others learn.
    - I really like you hidden wires in the crossovers - very good idea!
    - Thank you so much for the crossover schematic! ,
    - It would be so helpful if you can give a list Please ? . . .
    - to show which parts you used , - ( example only),
    - C1 - .0uF Miflex copper
    - C2 - 2uF MBGO
    - L4 - 0.62mH copper/wax jensen , ..... ..... etc . . .
    - ( it's hard to read them all in video, thank you)
    ----------------------------------------
    ----------------------------------------
    - here is a suggestion for you maybe to look into down the road - this is by another speaker builder , I can let you know who if you want to know latter ...
    - " After years of putting up with Duelund resistors and their terrible customer care (Brand new ones arrive already broken… (and they do) - sorry… they won’t refund or replace them) I finally had enough and found my holy grail. They are made by Path Audio of Poland and they are even better than the Duelunds, but that is only part of the exciting news.".

      Here is the caps list a couple minor changes from the schematics 2 Miflex are 0.02 instead of 0.01 either is fine
      everything else is as per schematics
      To see the rest properly use a large screen computer pause the screen around 20:40 make sure you are watching in 4 k should be extremely clear
      hope that helps.
      C11 0.01 mfd Miflex Copper
      C7 + C4 0.02 mfd Miflex Copper
      C1 0.02 mfd Solen
      C5 10 mfd Solen (not critical as mostly bypassed by R1)
      C2 30 mfd MBGO
      C3,(C7 3x47) mfd Kemit
      C10 1.5 mfd Mundorf Mcap supreme
      C9 6.8 MFd Mundorf Mcap supreme
      L1 L2 L4 14 awg Goertz Copper Foil Inductors
      L3 Solen 10 awg 3.7mh
      I heard a lot about Path Audio resistors of Poland I will give them a try sometime.

    Help ! I made a 3 way first order network that I love, sounds great 👍 I can't find info on making it a second order, is there a formula ? Can I keep the first order and add caps and coils for a faster cut off ?
    My home made speakers are better than most store bought but nowhere near the level of yours, I used Jantzen 16ga.coils and Jantzen caps, so the xovers cost me around $80 each again better than most production, but not on the level of yours, just so you know what my budget is/ what type components I'll be using

    • @Gabster1
      @Gabster1  Před rokem +2

      Yes you can add to it to make it second order
      But I would measure before and after to make sure you are getting a better effect just be careful as often the phase will shift and May need to reverse the polarity on the second driver
      The frequency response around the cutoff frequency should not have a bump or null

    Gabby - Just discovered your channel-- I'm very impressed with your speakers -- they are truly an work of art.
    I have several questions about your crossover schematic-- You said this is a second order design -- It appears to me that the high pass section is 3rd order -- if not, what is the function of the 10uf cap (C8)? I see you use bypass capacitors on the padding resistors at the input of both the high and band pass sections -- Is this to boost the output at the high end of each driver's range? Also, you are using bypass capacitors (.01uf) on many of the filter capacitors -- even on the capacitor in the low pass section, but you didn't use one on the 10uf cap previously mentioned (C8) in the high pass section-- why not? Also, you show a resistor (R4) in series with the filter capacitors in the low pass section-- what is the function of that resistor? You give a value of 330m-- does that mean milliohms? If so, I've never seen a resistor used in a passive network with that low of a value. Also, in the band pass section why did you place L1 in the circuit before L2 which would be a more conventional placement -- or does it make any difference where they are situated?

    You should have done path audio resistors... Quite a big improvement over the ones you used... But good build. Also your scale on sweeps make it 5db vs 10. Your waterfall z axis also is large time domain should be smaller to show true scale

    Hi there, I'm relatively new to DIY speaker building. I'm wondering if you could explain the difference between cheaper crossover parts vs more expensive. Just a general idea is fine. I don't quite understand, if the values are the same on both the cheap and expensive components the outcome should be the same right? Bear in mind I'm not very knowledgeable about the electrical parts yet, I'm just trying to understand why some advocate for super expensive components while others say it doesn't matter? I could be missing some simple info that makes my question stupid, but if that's the case I'd still like to know haha. Is the percentage listed on the components that the differing factor for cheap vs expensive components? If that's the case, does matching cheap components that measure the same have the same outcome of expensive components? Thank you gab! Edit: I've just built cheap kits, no designing yet but maybe it could be fun at some point to try, but I don't really understand enough yet haha

    • @Gabster1

      Hi Daniel
      When sound passes through inductors Capacitors and Resistors it changes
      For inductors the thicker they are the less loss in signal despite having the same inductance thicker wire has a lower resistance so your woofer will have more bass as there is less loss.
      For capacitors sound is far better with film capacitors and the better the quality the better the sound despite having the same value
      Similar effect with resistors
      Hope that helps
