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
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.
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.
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....
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?
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?
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!
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, 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 ?
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.
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?
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.
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.
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!
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
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
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?
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.
5:05 A couple of queries! Are resistors really, really flat, like WAY flat? Would an audiophile speaker maker who deals with way expensive cables etc., resist a tweeter?
Resistors are quite flat! Not perfectly, usually. But as near as possible. And putting a resistor in line with the tweeter will attenuate the volume down to help keep your high end tamed and matched with your midwoofer
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!
Hey! I have a tech question related to this video, can I use a resistor to lower the volume of a tweeter? if so, can you please explain how it's done? thank you very much for your awesome videos!
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?
kirby or whoever can explain to me in your last video on using the winlsd software, i'm building a set of bookshelf speakers and no matter what vent setting i put in its impossible to get it right, either to long for the box or i will get chuffing if i make the port small, this build is for the TCP115 speakers also tried slot port measurements but no different than the round port, and in your video we never got a final understanding on how to build a port to match the box and sound decent without chuffing. thanks for your input
Build the speaker and see if chuffing is really a problem. If it is, you can fold the port inside the cabinet like in iLoud Micro Monitor, or place it at the bottom like in ELAC AIR-X speakers.
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.
Hi Kirby!! I love your channel...you've inspired me to build some speakers...I have a question I hope you or a viewer can answer. When hooking up my system, the speakers just move in and out with a loud popping noise...any help is appreciated!@
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
Kirby, have you ever used passive radiators? I’ve been following your build guide videos, and I wanted to try going for the passive radiator over a port. I’d like to see a build from you with some passive radiator.
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

nope :)

Do you mean Electronic Engineer?
Oh my goodness, I was just hitting my head on a wall all night trying to figure out crossovers... You are a miracle maker!
Finally a proper explanation... You saved a LOT of time. Too bad I already wasted hours looking at super scientific explanations
Thank you for adding additional resources and describing what you are explaining before the you dive into the video!
Why did you stop making videos
I ve watched 100s of video for understanding crossover but this one I came through is best. Awesome❤️
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....

Hey i am building a similar speaker and i wondered if i need an amp, im using the same drievrs but im so conufsed

Hi Kirby can you make 5.1 channel speakers sets 4or 6 oms
does crossovers change the ohm load ?
What microphone do you use for your videos?

THANK YOU YOU¨VE BEEN THE MOST FUN SO FAR THANKS AGAIN
Excellent teach.thank you
Nice and clear explanation
Nice inform some time its depad u wich freqance u need to listing but good ideya that u give thanks
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!
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!
Thank you very much from Brazil
Does this help with distortion with both the woofer and the tweeter?
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
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
Very well done! I just learned a lot. thank you!
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 explanation . Thanks
Good teaching
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
This video is great
Salam paz.thanks
Excellent info - thank you!
Any place to get part in the uk or Europe please for a guy starting out
thanks bro.. appreciate it
Great information
MORE!! MORE!! MORE!! MORE!! Fully addicted to this series!!
Haha awesome! More to come. Thanks for watching!
If I was to buy a pre built crossover. Do they have a limit and specs on how much power they can take from the amp?
Great job sir
How do u learn this stuff ? Theres a lot to it no doubt .
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?
your video is so good
Awesome delivery of info!
so how do i know wich inductor value i need to drop off at a certain hz value?
Dear how to select capacitors and inductor value for different speaker wattage?
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.

Have you tried 2 ports
Attainable Audio if I choose 2 the ports have to be longer and won't fit the box specs
grerostov ill have to review on those types to get a understanding
Ronnie Turpin's vlogs What are you tuning to... What size box
It's magic!
Wont a lager speaker with ability to go from 40 hz to 1200hz sound lower to the ear than a smaller woofer with the same value?
a much awaited video
keep the good work brother
Will do! Thanks for watching!
Kirby Meets Audio appreciate your personal touch to your audience
How about using active crossover? ?
YES THE VALUES FOR THE PARTS
Would a 4th (5th, 6th, etc.) order have repeated the pattern you established, ie, L..C..L..?
Just the info I was looking for, explained cleanly and clearly. Thanks, Kirby!

Ll7oouou lol
And how do you realign the phase shift of the signal?
this is a great explanation. a very clear, well done video.
It makes of sense to go active with a mini dsp
At least initially to dial everything In
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
Awesome vid - thanks!
you could put some speakers in your ear things! :)
Thanks!! nice informative video!! I had that Aha!! moment :)
Hi buddy, next time please make a video about how to make a inductor coil for crossover
Nice video! Thanks
How do find out what power the speaker can take after implementation of the xover. Also speaker box volumes for woofers.
