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.
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.
Best description ever, I never thought I could get my head around crossover electronicy stuff so easily (I'm not smart, this comment is intended to illustrate how good the explanation is in this vid) thanks
Ah dude. Don’t do yourself like that. Smart is just a measurement of excellence in a specific field. There are tons of smart people out there but can theoretical physicist build a brick wall that will stand up for decades?
I started a electrical engeneering bachelor last winter. Never thought that the things we learn apply so directly. It was a breeze for me. Can only recommend
Maybe you know this, but this is not a straight resistive system so in most cases the electrical order will not actually match the acoustical order your aiming for.
Attainable Audio yeah speakers are also inductive components, so there's that. So it it a lowpass filter in itself, if I understand it correctly. But the inductance is probably so low that the characteristic frequency is relatively high.
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....
I like that robust workbench! Crossovers are as important as loudspeakers and often generic ones are not a perfect match for your needs! Welcome to rocket science!
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.
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
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.
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!
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!
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
Kirby, Very informative video!Crossovers have always been a mystery to me...UNTIL NOW!!! Your explanation was easy to understand. Hopefully,I'm armed with what I need for a project that's waited long enough... Thanks so much,Y-T
Finally some well documented video's in speaker building, ive been building several existing designs and want to build my own 2 way now. This helps a lot! thx
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 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?
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!!
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
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 ?
Much awaited and as usual, a great start to my learning courtesy of Kirby! Hope the busted finger is on the mend soon!! Best wishes from across the pond!!!
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.
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?
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
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.
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
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.
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.

Oh my goodness, I was just hitting my head on a wall all night trying to figure out crossovers... You are a miracle maker!
Thank you for adding additional resources and describing what you are explaining before the you dive into the video!
I ve watched 100s of video for understanding crossover but this one I came through is best. Awesome❤️
Finally a proper explanation... You saved a LOT of time. Too bad I already wasted hours looking at super scientific explanations
I started a electrical engeneering bachelor last winter. Never thought that the things we learn apply so directly. It was a breeze for me.
Can only recommend

THANK YOU YOU¨VE BEEN THE MOST FUN SO FAR THANKS AGAIN
MORE!! MORE!! MORE!! MORE!! Fully addicted to this series!!
Haha awesome! More to come. Thanks for watching!
Why did you stop making videos
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....
Great summary and intro - just what i was looking for
Excellent teach.thank you

Damn, havent seen Kirby in a while-he went full hipster!
Really excited about this series. Your build videos are inspiring but this is empowering.
That's awesome! I'm glad it helps. Thanks for watching!
Kirby Meets Audio it does much more than that! 👍👍👍
I'm stoked too cos I make my own speakers.
Great job sir
Thank you very much from Brazil
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!
im so happy that you made this video because i never seem to find a suitable crossover for my plans
I'm glad it helps! Thanks for watching!
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
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!
YES THE VALUES FOR THE PARTS
Great explanation . Thanks
Very well done! I just learned a lot. thank you!
excellent video thanks
Excellent info - thank you!
Just the info I was looking for, explained cleanly and clearly. Thanks, Kirby!
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.
Nice and clear explanation
The video(s) I have desperately been waiting for! Thank you...
You re the best
your video is so good
Amazing never understood crossovers before! Thanks
Thanks for all the compact infos. Keep doin'
This video is great
Good teaching
Awesome delivery of info!
thank you , glad i found you Kirby, amazing resource!

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!
This is the problem in India, bloody teachers teach every theory but no practical knowledge or don't know where it is used.
@@rajucherian I'm not from India
@@rajucherian i know right! they tell me "as long as youre in india, its your marks that count". really gets you down sometimes
Thank you so much for this!
It's magic!

thanks bro.. appreciate it
This is good stuff!
a much awaited video
keep the good work brother
Will do! Thanks for watching!
Kirby Meets Audio appreciate your personal touch to your audience
Thanks!! nice informative video!! I had that Aha!! moment :)
Awesome vid - thanks!
That was cool dude :) thx! very useful and clear
Very nice video. Love it!

Thanks man Looking forward to the next one
Thanks for watching!
I enjoy tuning in by ear and whatever I have in the drawer.
I want to learn how to build crossovers but, I need that hat even more.
you could put some speakers in your ear things! :)
THANK YOU SO MUCH.
Thank you
Awesome keep em coming brother!!!

Nice inform some time its depad u wich freqance u need to listing but good ideya that u give thanks
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
It makes of sense to go active with a mini dsp
At least initially to dial everything In
Great video. It's not rocket science but to explain it you have to put NASA hat on :)
nasa people aren't that smart, that's why elon Musk had to step in
Salam paz.thanks

Hi buddy, next time please make a video about how to make a inductor coil for crossover
Much awaited and as usual, a great start to my learning courtesy of Kirby! Hope the busted finger is on the mend soon!! Best wishes from across the pond!!!
Thanks for watching! I hope so too! haha
Hi Kirby can you make 5.1 channel speakers sets 4or 6 oms
That is really a simplification of capacitor and coils in relation to frequency..
Dude you all telented..
很喜歡您的解說，謝謝~
