Excellent. Helpful for this complete novice. Built my first wee speakers last year, full range 4 inch drivers. I actively avoided trying 2 way as was dodging the crossover "thing". After this video, may look at building a 2 way speaker....
There are some incredibly nice sounding full range drivers out there, I had a pair of vintage Coral Beta 8 35 watt version that outperformed everything I have now in sound quality. They sound out of this world, to this very day I have not heard better sound.
I have been mucking about with various crossover specs, both active and passive. My conclusion at the end of it is to go with active right from the get go. Since you can fine tune to any driver and any system. This way if you make changes later on you dont have to go through the whole drama of tweaking and re-tweaking.
Great video set. I have a question. My speakers are late 70s Pioneer Stereo Hifi 4 speaker, speakers. There's the usual bass, midrange, and tweeter, then theirs another piezo electric speaker. Do I need a 4 way crossover or can I double up the tweeters on a 3 way (doesn't sound good to me). Do you have designs for such a 4-way crossover system?? Thanks for any help and you make really great and helpful videos.
AC/DC electronics classes, showed me the real dynamics of filters. Chokes or "Inductors" increase in impedance with frequency, whereas "Capacitors" decrease in impedance with frequency. The 'slope' of a crossover, must derive from the driver impedance as well. A voice coil under a driven signal is not uniform in impedance, where the passive components in a filter are, and the difference is because magnetic flux in the motor of the speaker varies with frequency. Say you want the driver to roll off at a given frequency. The impedance of the inductor at that frequency would then be equal to that of the driver. Thus the driver is 3 decibels down or meaning that it is getting half of the power from the signal. In terms of crossovers, there is no such thing as a 'flat' response. Most entry-level, off-the-shelf speaker systems on the market today, employ only capacitors. They usually are not audio-grade film and foil, they're usually bi-polar electrolytic. The costlier systems are more costly, simply because they employ a true crossover. The actual response curve of a simple inductor is linear, but since we logarithmically scale what we see, it appears to slope. The actual response time of electrolytic caps in the super-tweeter region is too slow, such that film and foil caps outperform.
no time to discuss more? but time to play with fire woofers? I liked this video discussion. Maybe you could slowly expand on this subject: 2 way, 3 way, and 4 way crossovers, L-pads, (variable resistors, or potentiometers are not the same as L-pads), impedance matching, time alignment, matching the driver output of the hf - (mf)- lf (dB)., then electronic crossovers vs passive crossovers, bi-amping, tri - amping, powered sub woofer(s) - one or two.
I have a yamaha speaker I really love and only crossover it has are 1 cap to the mid range and 1 cap to the twitter... The woofer is fed full range, then I have a speaker wit a complex crossover that sounds very average, nothing stands out
Hey Kirby, I've been watching your videos lately and i find it super interesting and i actually decided to build a portable sound box myself. :D So I decided to use a stereo 20watt portable amplifier using adafruit max9744 based amplifier which uses filter-less spread sprectrum for the output section(no inductor/capacitor on the output side). I plan to use crossovers for my build and i'm not really sure if i can use the regular crossover components for these. What components would i need for a amplifier like this one? TIA
So, how do you evaluate a speaker in a live room situation? Speaker positioning will be fundamental to how it sounds, images etc, before even considering crossover configuration. Speaker manufacturers will have access to an anechoic chamber (their starting point, I would imagine) and will know how to exactly place a speaker in a live living room situation. For a DIY builder, a poor choice of speaker positioning could lead to an even poorer choice of crossover configuration.
3:52 Feastrex made some single drives that are 70 GRAND a pair! HA HA HA HA HA lol Still with the inherent problems like "doppler" (the treble is "excurting" it's way out of the driver) (lol) and the difficulty of a large 8" driver to go high enough. Time aligned coaxials like the KEF makes it way cheaper and the tweeter lacks the "doppler". Who would buy a Feastrex when it still retains those problems and when you can get KEF for a twentieth the price (with enclosures as well). lol
Its not intimidating per se. My problem as always been what can be used as a substitute as far as capacitors, resistors etc goes. Like as far as numeric values go, is there a window of what can and cant be used or does the exact model/voltage/etc have to be exact? Asking because I'd like to start repurposing old boards I come across. There's tons of little components that I can just desolder and reuse as I follow along in videos but they are not the exact same values as what I see in videos. Like on a video the requirement or suggestion(?) is an NP 100v 150uf for a subwoofer. Can a NP 100v 100uf replace that or are the values off so much that it won't "work" for a subwoofer and should be used for mid range instead as far as audible frequencies go? I just don't want to do something that would defeat the whole purpose of building a crossover circuit. As you can see I know very little about circuits lol. Please help, sorry for the novel.
Hello guys! Has anyone made a DIY crossover for a pair Micca MB42'S? (Look em' up, it's a very popular model of cheap desktop speakers) I've tried to Buy one but they do not ship that component to my country, so i've been trying to learn all i can to build one myself. My other opción Is to just Buy one from another manufacturera but to be honest i have no idea of what to look for. By the way i don't know anything about electrónics so this whole thing should be interesting
My friend, may I say something, hear me advise you to read a beautiful and deep book, the Koran and you are wonderful and you have beautiful ideas brother👍
I am just getting interested in the speaker bldg process..my question is “ would 3 or more drivers (mid-bass) be hooked in line to the same crossover? I know stupid question
One question. I have one tweeter and one woofer in my house so i decided build one speker. The problem is... my woofer is 550w,,8ohm and my tweeter 180w,8ohm they have potency (watts) very diferenty... can i build one speaker with them? Sorry my bad english. I use the translate.
Hey for those of us that are getting to this 4 years later... does anyone know how to get his worksheets? Loving these videos, so well-organized and easy to follow. Can't wait to get started.
I have a b&w 705 s2. The crossover has VERY SIMPLE but hi quality, thick gauge air core inductor and a mundorf silver gold oil cap. Is this simplicity good or bad? The whole speaker/cabinets is high quality, but seems it could benefit from small xover mods
I appreciate your effort in making this video but to me it sounds like you are just praise yourself. Just keep what you have learned for youself, a video like this is the wrong way: this is one of bad aspects of internet, people just see a 10 mins video and think they become technology guru. You have to study years on books and try to calculate with pen, paper and calculator. Then you have to spend money and time at the carpentry to work wood and time to learn how to listen. You are son of this era and you just pretend to design a crossover by typing some keys on your computer keyboard....with a calculator software even my niece can do that, you have not to show to the world how cool you are...loudspeakers design and building is art and requires years to manage, it's not just "see a YT video and downolad a free software". I have been teaching electroacoustics for some 8 years at the high school and since 2001 I am a contributor for the Italian DIY hifi magazine Costruire HiFi. Come back on Earth kid....
What if your niece can build a speaker that sounds as good as yours without having to study for years? Times change and a lot of things get easier. This is called progress and you should be happy for your niece instead of being frustrated with all your hard earned knowledge becoming obsolete. Come back to Earth pops.
Does Anyone Know If Capacitors Used On Woofers As High Filter And Nothing Else Causes "Holes" In The Spectrum? I Got A Speaker That Has A Cap On It Already. I Run A Manual Tone Generator And I Noticed There Is A Weird Peak In Excursion Around Is Resonant Hz Of 80Hz Free Air. What's Weird Is Usually It's Very Hard To Tell When Peak Excursion Occurs A Woofer/ Mid Range Driver. So I Wired The Speaker To Bypass The Cap And The Speaker Moves About The Same At 80Hz But Also Moves Alot More Than Before From 85-120Hz. I Ran A DSP With A High Pass Filter Feature And adjusted It Still It Sounded About The Same As The Cap It Came With. It Seems To Be About 125Hz Ish. But What's Weird Is The With The DSP Cross Over The Excursion Free Air Is Gradual As You Approach 80Hz. With Capacitor It's Seems To Have A Hole And Excursion Kinda Stops At 85-90 But All Of A Sudden Once At 80Hz Starts Moving Again. So Are Passive Crossovers With Capacitors Not Perfectly Flat On A Response Curve? Does It Have A Slight Dip Before The Actual Roll Off?
We spent a lot of time in my electrical theory class learning about filters. If theyd just told me it was related to speakers, I might've understood it way faster!
Kirby: can I use (2) 8 ohm 12db low pass passive xovers in parallel to reach a 24db/octave slope? Have an extra xover here & I'm curious about this application. Thanks for your videos. Al
Hey Kirby one quick question. I got 2 jbl prx 525 loud speakers that are self powered rated at 1300 watts peak. Long story short on both PAs both amps are gone. I wanted to know if i do an amp delete and run a high quality audio crossover for the Loudspeakers can i get away with that?
hello,how to connect 3 speakers in Crossover IN out T and W ,my car have Under seat Sub BMW f30 and doors speakers with Tweet ,my amp out 4 ohm ,sub under seat 4ohm and doors 4ohm speakers build in Tweet , jumper wire around the capacitor to bypass it, serial or parallel connect and this Crossover filter 4 ohm??Thank u
How can I bring down the mid sound of a 100watt 10 inch woofer? I have a dayton audio model ds270-8 by the way, from my favorite shop, parts express. Thanks
Great video I would like to replicate the crossover circuit of a Ar3a vintage speakers with today components is that possible to do? Is there a blueprint for crossovers circuits?
You sir, are a teacher first, audio guy second. Excellent video! I wish there was a “really like” button. For hobbyists, this was the perfect split between what crossovers do and then how they do it.
no speaker has flat frequency response! In order to get the best possible sound, you also need several parts. over + and - to reduce frequencies it is too much of! coil to capacitor on bass to capacitor to coil on treble is all too easy crossover! all speakers have different sound so crossover must match speaker
there is a software crossovers so there is no need to use a hardware crossover also the hardware crossover has a slow decrees but with the software crossover the sound will stop instantly at the crossover point this means the software crossover works a lot better then the hardware crossover
Great video dude! I like how you explain things, nice and casually. I have two Sonic PA cabinets that I would like to build matching crossovers for. The only intimidating part is the fact I would need both low and high pass filters. You have inspired me to really think about taking it on and I’m gonna keep following this series. Thanks for your work!
Great video, thx a lot. I have 2 questions. I checked some speakers with just a capacitor as crossover for the tweeter and they all have different capacitor values between 1.5-4.7 µF. Is this because the manufacturer wants different sound or the tweeters are different or the amplifier is different ? How do I choose the right capacitor for a tweeter ?
This whole series has been a great insight up to now on how to build a speaker. can't wait to complete the full series and obtain total knowledge....lol...keep it up. When this video series comes to an end I will show one of my own speakers.
0:53 What if you bought really good speakers and used them as reference speakers? Copy the speaker's sound with the crossover and then tweak that just a little bit and make them maybe sound a bit different (to your taste) but not too much different. The only trouble is that I don't have 3 grand for really good reference speakers. Would that be better than just guessing?
Or just do it the 1950s way, single capacitor like in my 1957 Blaupunkt Arkansas😂 There is no coils just a single 4uF capacitor than I replaced with a brand new one, I don't think it even filters that much. My Canton GLE 100 speakers from 1979 have a beast of a a crossover, that I also recently replaced with electrolytic caps cause I am poor. Will change to polys when I have the cash
I learned that xc=1/2pi.fc Xc being equivalent resistance of a capacitor and f being frequency And: XL=2pi.fL L being inductance. Each being in their true unit Henries farads and Hertz
Talk about bsc. You need a somewhat decent mic to measure baffle step. I use a at2020usb and holmimpulse. Typically my bsc circuits are doing about 9db between 200hz and 900hz.
When designing a crossover you really really don't want to use the k.i.s.s. method. There are three types of power: True power, Apparent power, Reactive power. True power is input power, Apparent power is what's there (apparently) and Reactive power doesn't exist. You need to know how to wrangle all three types of pixie before designing your own crossover or you will do poorly.
Kirby, PLEASE SEE THIS. How do you feel about DIYperk’s avoidance of this step? And by using a crossover setup instead of DIYperk’s method, can you change the number of drivers you can use?
DIY perks usually uses small full-range speakers, so they don't strictly need to have crossovers in place, however, they also have substantial limitations in reproduction due to their size, excursion, and mechanical and electrical spring force. You can also just buy preassembled filters or crossovers if you're feeling less motivated to figure it all out yourself. Nothing wrong with that, just need to match them properly and make sure they're for the appropriate impedance for your speakers, etc.
I have made a mobile speaker with Dayton mid/low woofers (nd105-4) and some older recycled good quality Quadral tweeters... the problem is that the highs are waaay to sharp and claps in old school rap are so uncomfy to listen... the highs are not even crisp, idk if i can do something about it without changing the tweeter, cause in the original quadral speaker they did sound awesome... :( (Cant even look how the original crossover was build cause my stupid ass just throw them away because they didnt work)
You had two inductors, and with a 1st order, you could use a single inductor @ the value of the sum of both your inductors. But there is a purpose for that. I was puzzled how I could place a cap from + to - without having to resist it (otherwise it would short circuit the treble) and (even with resisting it) I would still lose some treble (robbed from the tweeter). So I put a small inductor in series with the across cap and the added resistor. It worked (I suppose) but your double inductor idea is better (I reckon). Now I know. You used two inductors that are half the value (one on each side of the cap connection) so it blocks the treble that would otherwise be short circuited. Well done. Make some more crossover stuff.
Biggest mistake I ever made was opening up an old pair of Gemini gsm 1545s last week, thinking I could replace the crossover and fix them. I didn't even know the difference between a resistor and capacitor and, now, here I am down the rabbit hole.
I can never find an exact match, on Parts Express, when I search for specific inductors and capacitors. Besides not understanding what types work best for my needs, my question is can I use something close? Instead of 6.6uf is it ok to go with 6.8uf?
All the big words and "maths"...hilarious. Crossover design has always been confusing to me. This was a great 50k foot view of how they work. A driver always has it's own inherent impedance. Will a crossover alter the amps perceived load of a driver, where you have to run things in series or parallel? Thanks Kirby!!
I've read that ideally you want to use nothing BUT 4th order crossovers in order to prevent phase issues and haveing frequency level bumps at the crossover point because of excess blending or something like that. I also heard 1st order crossovers were the worst at this, and the most likely to damage speakers when it came to cutting out low frequencies because they didn't cut them strongly enough. And that they were also the worst for subwoofers because your subs would start playing the hum of male vocals if you had the crossover point anywhere reasonable like 60-100hz. Care to elaborate or give your thoughts on that?
Hy kirby.. Im from indonesia.. Im audio addict.. And now i have idea to build speaker for my desktop.. And i dont understand about electricity.. Can you help me.. And put the indonesia language.. I mean text..
Oh my goodness, I was just hitting my head on a wall all night trying to figure out crossovers... You are a miracle maker!
Excellent. Helpful for this complete novice. Built my first wee speakers last year, full range 4 inch drivers. I actively avoided trying 2 way as was dodging the crossover "thing". After this video, may look at building a 2 way speaker....

THANK YOU YOU¨VE BEEN THE MOST FUN SO FAR THANKS AGAIN
Been so waiting for this one. Hope your broken digit heals quickly!
I hope it helps! Part 2 is coming next week. Thanks! me too!
Great summary and intro - just what i was looking for
I have been mucking about with various crossover specs, both active and passive. My conclusion at the end of it is to go with active right from the get go. Since you can fine tune to any driver and any system. This way if you make changes later on you dont have to go through the whole drama of tweaking and re-tweaking.
Excellent info - thank you!
your video is so good
Why did you stop making videos
oooooo yes, can't wait to watch
Thanks for watching!
It makes of sense to go active with a mini dsp
At least initially to dial everything In

Great video, thx a lot. I have 2 questions. I checked some speakers with just a capacitor as crossover for the tweeter and they all have different capacitor values between 1.5-4.7 µF. Is this because the manufacturer wants different sound or the tweeters are different or the amplifier is different ? How do I choose the right capacitor for a tweeter ?
This whole series has been a great insight up to now on how to build a speaker. can't wait to complete the full series and obtain total knowledge....lol...keep it up. When this video series comes to an end I will show one of my own speakers.
I'm so glad its been helpful! Can't wait to see it!
Where's part 2? Can't find it.. Sorry...
How do u learn this stuff ? Theres a lot to it no doubt .
What microphone do you use for your videos?
0:53 What if you bought really good speakers and used them as reference speakers? Copy the speaker's sound with the crossover and then tweak that just a little bit and make them maybe sound a bit different (to your taste) but not too much different. The only trouble is that I don't have 3 grand for really good reference speakers. Would that be better than just guessing?
The video(s) I have desperately been waiting for! Thank you...
Thanks for all the compact infos. Keep doin'
a much awaited video
keep the good work brother
Will do! Thanks for watching!
Kirby Meets Audio appreciate your personal touch to your audience
Or just do it the 1950s way, single capacitor like in my 1957 Blaupunkt Arkansas😂 There is no coils just a single 4uF capacitor than I replaced with a brand new one, I don't think it even filters that much.
My Canton GLE 100 speakers from 1979 have a beast of a a crossover, that I also recently replaced with electrolytic caps cause I am poor. Will change to polys when I have the cash
I learned that xc=1/2pi.fc
Xc being equivalent resistance of a capacitor and f being frequency
And:
XL=2pi.fL
L being inductance.
Each being in their true unit

Talk about bsc. You need a somewhat decent mic to measure baffle step. I use a at2020usb and holmimpulse. Typically my bsc circuits are doing about 9db between 200hz and 900hz.
When designing a crossover you really really don't want to use the k.i.s.s. method. There are three types of power: True power, Apparent power, Reactive power. True power is input power, Apparent power is what's there (apparently) and Reactive power doesn't exist. You need to know how to wrangle all three types of pixie before designing your own crossover or you will do poorly.
well undertand a few, need more informations.
Kirby, PLEASE SEE THIS. How do you feel about DIYperk’s avoidance of this step? And by using a crossover setup instead of DIYperk’s method, can you change the number of drivers you can use?
What project are you talking about?
I don't know what you're talking about. Will you post a link?
DIY perks usually uses small full-range speakers, so they don't strictly need to have crossovers in place, however, they also have substantial limitations in reproduction due to their size, excursion, and mechanical and electrical spring force. You can also just buy preassembled filters or crossovers if you're feeling less motivated to figure it all out yourself. Nothing wrong with that, just need to match them properly and make sure they're for the appropriate impedance for your speakers, etc.
I have made a mobile speaker with Dayton mid/low woofers (nd105-4) and some older recycled good quality Quadral tweeters... the problem is that the highs are waaay to sharp and claps in old school rap are so uncomfy to listen... the highs are not even crisp, idk if i can do something about it without changing the tweeter, cause in the original quadral speaker they did sound awesome... :( (Cant even look how the original crossover was build cause my stupid ass just throw them away because they didnt work)
Crossovers simplified. Get well soon.
Shut up and build the crossover
You had two inductors, and with a 1st order, you could use a single inductor @ the value of the sum of both your inductors. But there is a purpose for that. I was puzzled how I could place a cap from + to - without having to resist it (otherwise it would short circuit the treble) and (even with resisting it) I would still lose some treble (robbed from the tweeter). So I put a small inductor in series with the across cap and the added resistor. It worked (I suppose) but your double inductor idea is better (I reckon). Now I know. You used two inductors that are half the value (one on each side of the cap connection) so it blocks the treble that would otherwise be short circuited. Well done. Make some more crossover stuff.
Biggest mistake I ever made was opening up an old pair of Gemini gsm 1545s last week, thinking I could replace the crossover and fix them. I didn't even know the difference between a resistor and capacitor and, now, here I am down the rabbit hole.
I can never find an exact match, on Parts Express, when I search for specific inductors and capacitors. Besides not understanding what types work best for my needs, my question is can I use something close? Instead of 6.6uf is it ok to go with 6.8uf?
Hi buddy, next time please make a video about how to make a inductor coil for crossover
All the big words and "maths"...hilarious. Crossover design has always been confusing to me. This was a great 50k foot view of how they work. A driver always has it's own inherent impedance. Will a crossover alter the amps perceived load of a driver, where you have to run things in series or parallel? Thanks Kirby!!
Salam paz.thanks
I went to request free plans, all I get is a notice that I am suscribed to a maillist, no plans.
I've read that ideally you want to use nothing BUT 4th order crossovers in order to prevent phase issues and haveing frequency level bumps at the crossover point because of excess blending or something like that. I also heard 1st order crossovers were the worst at this, and the most likely to damage speakers when it came to cutting out low frequencies because they didn't cut them strongly enough. And that they were also the worst for subwoofers because your subs would start playing the hum of male vocals if you had the crossover point anywhere reasonable like 60-100hz. Care to elaborate or give your thoughts on that?
Hy kirby.. Im from indonesia.. Im audio addict.. And now i have idea to build speaker for my desktop.. And i dont understand about electricity.. Can you help me.. And put the indonesia language.. I mean text..
