Your videos are interesting and helpful. I liked especially the video where you experimented, to show the impact of the inductor location. I have observed that not all speaker builders have this knowledge. Tanks for these nice videos.
Gabster I appreciate you alot. You helped me with my first crossover. You are a genius. I appreciate how you break down how it's very Important to make sure their's no interference in your system. Wow! Outstanding work!!! And thank you a lot for your knowledge.
Hi, I've been dealing with electronics all my life and I'm also a fan of good sound, I have industrially made speakers, but I made my own crossover tuned using a generator and an oscilloscope. Your work is absolutely amazing (I immediately subscribed) and I find your choice of capacitance meter all the more odd because you use the most inconvenient way to measure with DC charging. These meters work on the principle of counting the time it takes for the capacitor to charge - this method is very indicative and completely unsuitable for audio applications. Capacitors need to be measured using an LCRmeter with alternating voltage at their operating frequency - the change in frequency acting on the capacitor greatly affects its capacity. Measuring capacitors is exactly the same alchemy as correctly placing the individual parts of the crossover. I praise the ESR measurement 👍 but I personally also measure the EPR and DC leakage at the maximum operating voltage on the capacitor before use - these measurements tell us almost everything about the condition and properties of the capacitor. What you made is absolutely amazing, including the work procedures and the measurement of acoustics using a microphone is top notch, and that's why I didn't understand the measurement of capacitors with a clamp multimetr on which this function is only additional. To compare it to audio technology, it's like someone bought a Jamo Oriel, connected all the speaker terminals with a thin bell wire and connected, for example, a McIntosh MC2KW. I have a life motto that works not only in the area of audio - The whole system works like its weakest link. In conclusion, I would like to apologize if my comment is not well understood, I do not know English very well and I am helping myself by translating. Nice day 🙂 Tom
Awesome video(s), dare I say therapeutic. I often thought about building my own speakers, but crossover design is a bit daunting to me. Thanks for sharing.
Thanks if you pick good drivers the second order crossover is simple. There are a lot of ideas start with a well known design plans and do the same at first.

Hello! Good work! I construct my crossover with polymer capacitor but i decided to use ferrite core with air gap (because copper wire is expensive and size of coils without any rod is too big).
Impressive work! Question.. Im just looking to upgrade existing components in my Magnepan 1.7i xo. Ive read that adding a bypass cap for tweeter should be about 10% of spec value. If 10uf is spec value and 1 uf is bypass value, should the main cap be 9uf since caps in parallel add thus equalling 10uf? Thanks!
Thank you so much for your videos, very appreciated! I'm about to embark on a similar project and just curious, did leaving the crossovers uncovered give you any problems? Like dust collecting or oxidation from moisture in the air?
Second order crossovers are not that complicated once you decide the transition frequency based on the drivers parameters You can do a bit of simulation in software but to be honest the bulk is done by first working on 1 driver at a time then all 3 with hundreds of sweeps and rew measurements and listening After some practice you have a tough idea what values to use then fine tune from there
Would it be a good idea to upgrade a 2way passive crossovers with higher end components (caps, resistors,etc;) for car audio too? If so, I've got a project that I need help configuring for a component system that I upgraded the size tweeters and drivers for my truck...
One wonders ... thick power cords, thick speaker cables, thick interconnects ... and then thin wires in the crossover ... which compromises, or defeats the purpose of, all those nice thick wires elsewhere? What are your thoughts.
I thought the same and when I built my gr research nx otica crossover I wired it using kimber cable 8tc braided cable... What a pain to do but I'm glad I did!
You have a point, these appear thin but they are 12 and 14 gage silver plated ofc copper they look thin because the ptfe jacket is very thin. also as noted by others below short distances are not as critical and most connection have silver solder on top.
Gabby, if I were to replace the ferrite core inductors in my xo, I would measure the DCR in them as well and buy and air core inductor with the closest DCR to the original ferrite core correct? I am assuming that the designer of my speakers took into account the DCR of the ferrite core inductors he used. They are Proac speakers btw. Thanks!
The dcr on a ferrite core will be very low as they only use a short copper wire you would need to use a much bigger gage wire to get the same dcr but yes you are correct. A bigger dcr will reduce the bass a tiny bit so the smaller the better.
@@Gabster1 so do I need to measure the DCR of the ferrite core inductors currently on the board? Or just get an air core with the lowest DCR? I’ve heard that some speaker designers take into account the DCR for the design. Is that true? Or as I said before just get an air core inductor with the lowest DCR? Much appreciated !
@@Gabster1 is there any other way I can contact you and pay you a fee by the hour so you can guide me through my speaker ‘ upgrades’? Would you be interested ? Thanks
@@Nightjar726 I would get the one with the lowest dcr the thicker the copper coil the better you will probably need a 12 or 14 awg to get close to the ferrite dcr in my case I used a 10awg but that is huge you put that inside a speaker now you are affecting the cubic volume If it is a bookshelf proac would use a 14 awg A big tower use a 12awg On another note you may want to consider spending that money on upgrading the mid and tweeter capacitors you will get more bang for the $ if you can afford all even better Don’t go too Crazy at some point you are better off getting better speakers for that money. Hope that helps
@@Gabster1 getting better speakers is not as fun. That would be too easy. Ha. I’m sure you understand that as a tinkerer yourself. I want to learn from this experience and try and squeeze as much as I can from these speakers. I am also thinking of putting in a beryllium tweeter to replace the soft dome. Hope that makes sense. So you are saying that I do not need to match the exact DCR the designer used for the speakers? Oh and one more question. I think I have the specs for the inductors. But if I want to measure them myself would I get a LCR meter? What would I need to measure the inductance and DCR resistance of each inductor to be 100% sure? Much appreciated
The Idea is the same just need thicker gage inductors and higher W rating on resistors and higher Voltage on Caps you can measure across each component say at a 100w and do the math for a 1000. keep in mind that a 1000w is not meant for home use at least not on full power You would need Higher rated ears as well :) most amps that are a 1000 w rated don't end up driven past 200w just nice to have the headroom.
Hi. I wonder if you can make crossover for my open baffle speakers or maybe you know somebody who can design and build crossovers. I'm from New Jersey USA. My project is Raal The Lazy Ribbon 210-10 Compremag ,Lowther PM5a ,Great Plains Audio Model 416-8B Metal frame is from Pure Audio Projects
Hello! I follow you, I'm from Romania. much cheaper and more professional, solve with a 3-way active crossover! I switched from passive to active on 24 db octaves and the result is much, much better. and you don't need powerful amps!!! I will post a video so you can see what I did. but I like how you work.
@@Gabster1 ok cool no problem , I’ve been on this project for almost 4 years now, looks like I’ll have to use DSP plate amps . Anyway all the very best from Amami Japan
@@Gabster1 in one vid. he uses the prob to locate a quiet zone on a board and relocate a choak I believe to improve a test device he was evaluating. the value of it in diy audio is huge. sone other inventions are equally impressive.
i'm a novice about crossovers yet i enjoyed watching every second of it.
i just hope we can hear your speakers sing, definitely they sound amazing.
Glad you enjoyed it!

Loved it sir!

I'm about to embark on a similar project and just curious, did leaving the crossovers uncovered give you any problems? Like dust collecting or oxidation from moisture in the air?
Not at all I use a Swiffer from time to time or a Photography air blower. having them outside not subjected to the vibrations helps with better sound.
Great video. Amazing build. Everything is meticulously engineered. Is the connecting wire pure silver wire? Where do you buy it?
Can you please share the formulas and theory of how you calculated all the components. Thanks for the interesting videos!

Lovely job 👍

Short distances don't require same thickness as longer ones.

You have a point, these appear thin but they are 12 and 14 gage silver plated ofc copper they look thin because the ptfe jacket is very thin. also as noted by others below short distances are not as critical and most connection have silver solder on top.
how thick are the wires in the voice coils, or the traces inside the amplifier hmm ?
zip ties compress the coil material leading to possible failure down the road, & actually the same goes for capacitors, don't use zip ties
Does diy crossover make sense?

Can you show how to make a 3 way crossovers for over a thousand plus watts speaker system ty
The Idea is the same just need thicker gage inductors and higher W rating on resistors and higher Voltage on Caps you can measure across each component say at a 100w and do the math for a 1000.
