I think I will never build a speaker in my life, but I still enjoy the videos! :P

[@KirbyMeetsAudio]

This is great. Thanks so much for watching!

Austin Bauman hahaha ok :P

[@jakemilitano2453]

Eduardo same here

[@TheCalebf]

may never build a speaker but may still need to build a crossover

[@swagonman]

I like starting with a notch filter on the tweeter and an impedance compensator on the woofer. Then build the crossover on top of that. It enables the phase relationship between the woofer and tweeter to be more constant across the frequency range above and below the crossover frequency. In other words, the speaker drivers look more like resistors to the crossover network, so the crossover has a more predictable response. I’ve done this and then built 1st order high pass and low pass, which combined with the notch and z-compensation, acted as a 2nd order crossover quite nicely. Worked super well for my project. Anyway, just something you could try on the software pretty easily and see if you like it or not.

[@KirbyMeetsAudio]

I will try this for sure. Thank you for sharing your experience! And thanks for watching

[@swagonman]

You’re welcome. I enjoy ur whole channel. Keep ‘em coming!

[@Bucefal76]

Good approach. Instead notch filter for for tweeter you can use L pad, it also makes impedance more flatten and easy for filters. This is additional reason to do not use single resistor for tweeter before filter, but use L pad after (!) filter. To the filter see easy impedance.

[@kennmossman8701]

WTF use a notch filter?

[@scottcarlon6318]

I tried looking notch filter and impedance compensator up on Parts Express and struck out, is there another name for these parts?

[@richardk.4131]

The Vituix software demonstrated has changed dramatically since this video and seems much harder to use. Any chance of getting an update basic guide?

[@Phanex]

had the same problem XD i just dowloaded an older version 1.1 i think that worked.

[@rezo786]

@@Phanex cannot find V 1.1

[@ryry7886]

I love the FDR parameters. LOL Great dude.

[@belovedconsole]

This was so great, but basically the software needs specific data from the manufacturer, right? And not all include that, so it will only work on some drivers?

[@m.r.3128]

Great minds think alike/fools never differ, unsure. Really appreciate the direction you're heading in man - word on the street is you're a very cool dude and this vid proves it. I've learned enough to know, I didn't know enough to know, I didn't know. ✌🏽

[@whozaskin3639]

Many studio monitors are 2 way speakers, and all this may be a reason. Of course then there is the driver itself, the way an enclosure alters it's response, and the room they go in. Speakers. Lots going on! Great video!

[@kimmosto]

Thanks for this video Kirby! This is fun and relaxed addition to my "official" lessons with boring female machine voice by MS :) Video for version 2 with comprehensive off-axis responses 0-180 deg. in two planes could be helpful at this point because new version with free form schematic, OP amps and other parameterized library blocks has been available for few months now.

[@jordanhart9708]

This is great... So long as you can find the files you actually need to make it work. Without them, you're out of luck.

[@derrickhaucke9909]

So I have built a few proven designs and a few of my own full range designs. After watching your videos I really want to try my hand at a full custom design. Keep up the great videos.

[@eduardoquintanaavila.6290]

Hola. Hace como 20 años empecé a fabricar crossovers de 3 y 4 vías de 2o orden de manera manual, fabricando también los embobinados con las formulas Butterworth pero desde hace como 5 años empecé con las formulas Linkwitz par obtener una mejor respuesta pero lo que ahora veo con estos softwares me tienen realmente asombrado. Esto es una maravilla para mi. Gracias. Hello. About 20 years ago I started manufacturing 3 and 4-way 2nd order crossovers manually, also manufacturing the windings with the Butterworth formulas, but about 5 years ago I started with the Linkwitz formulas to obtain a better response, but what I now see with These softwares have really amazed me. This is a wonder for me. Thank you.

[@JoelBursztyn]

I liked very much your videos, I am building now speakers with DSP crossover, but my target is to replace it with analog. Your video showed me that I can do that easily when I will be ready for that. Thanks a lot. YOU R Great!!!

[@ianskinner1619]

this was a great video, i only wish you would have described the various lines , I eventually figured out the bold grey was the average sound for that build.

[@mikelewis9414]

Where can you get spec files for drivers that aren't Dayton? No other manufacturers seem to have them.

[@motodork]

You either have to create them yourself by conducting measurements of the drivers, or you use the built-in tool that lets you import the data from images of graph data

[@Luke-qs2cg]

Trace the graphs given by the manufacturer, but neither are going to give you the best graphs to work with. Actually assembling the speaker, then measuring the drivers using dats will take into account the fact that they are now sitting Inside your actual speaker. Thats why professional crossover designers, don't start the crossover until the speaker design is complete. You gotta have a speaker to give them for them to give you the best results. Not just drivers.

[@asymantix1611]

wouldn't it have been cool if kirbert told us this? Thanks Moto

[@JonathanDFielding]

The reason the frequency response of the woofer and teeter don't blend well is bc the teeter and woofer are 180 deg out of phase from each other. One trick to always check is invert the tweeter. Sometimes that help the transition band response to invert the tweeter. This applies to active fillers too.

[@zoroluva]

I noticed this when looking at a GR Research upgrade kit for a Klipsch RP-600M. The tweeter terminal was inverted. That threw me all the way off! Thanks for this clarification.

[@midoyoyo3164]

Thank you very much .. you made me seriously consider building my own speakers now ... i downloaded the software and started training on it ... made a couple of nice 2 way crossovers with dayton audio data sheets ( just for fun ) BTW about taking a photo for the nice spots during crossover designing then tweaking again ... you can click ctr-s to save your work then continue tweaking ,so if you want to go back to your nice spot you can return easily that worked for me just fine :)

[@DanielAwesomesauce]

Thank you for a very educational, informative video.

[@BeckOfficial]

If you don't see any graphs it's because you need to go to the crossover tab and connect the generator (left side) to the driver(s)

[@dtrain8335]

Great video and great software. After playing around with it for a little while it dawned on me that enclosure type and size can really change the frequency response of a driver pretty drastically so how should that be taken into consideration when designing a crossover? Is that kind of why you recommend tweaks after the speaker is built?

[@bryanbassett2110]

The way Kirby proposes to design the crossover is fundamentally flawed, because he suggests that you use the FRD/ZMA files for the drivers. Not only will the drivers you actually receive probably have a different response, they also will be placed in a box, as you mention. When you design a crossover, you really should take measurements with a measurement microphone of the drivers in the box before you start to design the crossover. If you just use the FRD/ZMA files, your speaker's frequency response will look almost nothing like the theoretical model.

[@vittoriosilva1454]

The resistor in series with the inductor is not an actual discreet component ... It is a virtual component that represents the dc resistance (R) of the inductor ...Gauge of wire determines the amount of power you can pass through it without burning it up ...

[@martg.b.6160]

Ive been using the v2 version of the program. If I hit Ctrl+Z it undos the changes. You can also undo the changes in the optimizer, there is an undo button.

[@willmac5642]

Where to find zma files for drivers and tweeters? I find it hard to make these. Also I can't understand why only Dayton supply them, it wd be great if SB, Scan etc did this

[@t1mm3h]

instead of using your phone to grab pictures from the software, why not looking into using "Snipping Tool". It's a small utility built into Windows that do just this and it's really easy to use! Then you can save your settings right into the folders right away and is probably a little more streamlined than the phone approach.. ;)

[@maxbombel877]

Why not just save the project before going on with tweaking? And maybe add version numbers to the saved projects. This way you can simply load a previous version if your tweaks failed.

[@fxprocc]

Very very easy to follow, thank you

[@johnleewright345]

Love the videos. Long cast is to keep you from turning your wrist.

[@eeamm7087]

This software is good for specific brands with datasheets, how about using a speaker taken from garage? The only data you will have is size and inductance. A good software should cover most of speakers.

[@FelixRisingOriginal]

I always get caught up thinking about the phase response of each speaker. That must have a big impact at and around the cross-over point.

[@1pdigit]

You should check out Xsim, it's free and it's super stream line. It also allows you to save the XO's you build so no more phone pics! It's not good for beginners though, it doesn't build anything for you, like you can't input a XO freq and slope and go from there but I can tell you wouldn't have any trouble. Also, don't worry about importing the off axis responses, it just clutters the graph and you don't really use them to design the XO anyway.

[@PS3RatBag98]

1pdigit xsim is amazing, so easy to use

[@KirbyMeetsAudio]

Xsim is great! I was using it before finding Vituix. I've been using this software more because of all the added tools. I haven't played with all of them yet, but I like having them in one program. It's also a little more helpful for new people. The off-axis actually only show up when clicked on, so they don't really clutter the graph too much. Thanks for watching!

[@1pdigit]

Kirby Meets Audio Thanks for posting! This is a fun channel!

[@kimmosto]

I would not advertise other tools here. XSim is a good program but really limited in many ways compared to VituixCAD package.

[@1pdigit]

kimmosto- I'm not really advertising anything here, I just like the program and thought i'd share some info. That's the spirit of this channel, sharing info.

[@robertparkphotography2451]

You need to invert your tweeters phase with that xo alignment. That big hump and dip should have been your giveaway. You compensated with too much overlap but scrambled the phase and impulse response. The acoustic rolloffs are not going to be optimal. Good video on using the softwares features though.

[@eatdrinkwineguy]

Thanks for taking the time to these videos. Great learning.

[@beatliner1009]

What about baffle step, phase matching, group delay, measurements? Unfortunately it's not that simple as You make it but nice video

[@Onewheelordeal]

Clearly states this is just an intro for diyers, pretty sure noone thinks they'll start a world-class speaker company off one KZbin video. Building yourself a speaker to personally experience and enjoy can even be so much simpler than this. I've had fun making speakers from a paper plate and business cards

[@leetharps579]

[@audioburrow1258]

But whet you mounted your speakers into box the impedence and ferequency response will be different than during free air measuremnts...

[@Slane583]

I'll have to fiddle about with this software. It would be great for making enhanced crossovers for my Minimus 7's without using someone else's design. So far the best I've done to them was upgrade the woofers and the capacitors for the tweeters. :)

[@KirbyMeetsAudio]

Nice! If you've changed out the woofers, you'll probably hear an improvement with a crossover designed specifically for them. Thanks for watching!

[@Slane583]

They sounded great when I was listening to them but my stereo receiver is from the 70's. Being old it started acting up when I lasted used it. So I haven't used it for months. I need to take it apart and fix it but I'm a bit afraid of making it worse. I'd love to eventually upgrade and replace all of the capacitors & resistors in it. The woofers I used were Dayton Audio PC105-8's, so I'll have to see if I can get some bass out of them when I'm able to make crossovers. I mainly bought them because they were affordable, looked good, and fit the Minimus 7 boxes without mods. For having no bass they sound fabulous when paired with a subwoofer. :)

[@AudiophileDIYer]

There are a lot of Xover design software or online calculator now, back in my day, I keep using 1/(2*pi*freq*r) for basic tweeter Xover and R/(2.Pi.Freq) for woofer, now I nearly forgot how to calculate without software....

[@motodork]

I downloaded VituixCAD 2, but none of the speaker data I loaded into it shows up on the SPL and Impedance graph. Also, the GUI looks quite a bit different now from what's in this video (this video highlights verion 1.1, which is somewhat older). If you go to the Vituix website, you won't find a download link for their older 1.1 version software. However, if you copy the download link to version 2, then replace "2" in the link with "11", it will download the older version 1.1. And now you can follow along with this tutorial much better. You're welcome.

[@christofferherala4521]

[@slominb]

Thank you for all the help. Preferably where should our impedance peak or center be?

[@scottcarlon6318]

reading the ''manual'' it became crystal clear that this software is way over my head. I think the Birds in the 60's had a song about crossover software, it was titled ''eight miles high''. I think my only hope is hit and miss, I wish there was an online class I could take to help a non computer literate guy like me. If anyone has found a solution, please share.

[@sperdenv5871]

If you can't find the data of the woofer or tweeter just use the Omni calculator site, it's fast and easy to use. Only need frequency response and ohm rating.

[@michasy2221]

do you have a tutorial without using FRD and ZMA?

[@longbyrd2000]

I would love to see you do a DML build with exciters.

[@geokrilov]

One can never make a loudspeaker using SPL and impedance graphs from datasheets and not obtaining them from real measurements of the drivers in the real cabinet. You also can't design a crossover simply by using CAD and not measuring the result and correcting it several times according to measurements and listening.

Then after long crossover designing, components hunting, spending money, you would end up with your tone control or equalizer adjustments to reduce or to boost up certain freq depend on your mood or taste.

[@guitarlearnerish]

Of all the things that prevents me from trying to building 2 way, MTM or 3 way speaker is the crossover, I know that off the shelf crossover r not ideal. But still can't comprehend on how to make one myself. Its the cost of trial & error that keeps me from trying it Still gonna try to learn it. But until I finally managed to understand it, I'll stick with single full range driver for a while.

[@flightharbinger7218]

Yeah, I've used Xsim a bit. Vituix is very similar, especially V2, and adds a few other tools I enjoy. Thanks for watching!

[@8bitbunny_VR]

Xsim doesnt have enclosure params aside from relative mounting depth sadly

[@ImpulseAudioSpeakers]

Ramon Schepers if you need a box design tool there is WinISD which is very popular.

[@kimmosto]

VituixCAD has also enclosure and diffraction tools. That combination is far more versatile than WinISD and most of the other box simulators: Vituix is capable to generate directivity information for simulated driver+enclosure system.

[@ImpulseAudioSpeakers]

kimmosto not sure why you would want that from a box simulator. Maybe to do prelimary design checking. Otherwise it should be captured during measurements for XO design. In any case, Vituix looks very capable. Just was offering another option.

[@karollepeto8924]

[@henkko7343]

Hi. Great video. Many many years ago I built a pair of speakers. Two tweeters, two mid range and two bass speakers in each cabinet. I knew nothing about electronics then and still today and asked somebody else to build crossovers for me. The result was a dominant mid range and weak bass and weak tweeter range. Exactly the opposite what I wanted to achieve. I was looking for much more bass and tweeter and very little mid range. I would now like to correct the faulty crossovers. Could you help me with the correct design? Thanks.

[@vicg5323]

I tried building a few witht with those online calculators and the result was horrible. Finally did a few DIY form Parts-Express and Amazon with good results. Thank for showing why the online calc don't work. They are not a complete tool. Is the the software you are using free or must it be purchased. Looking for to repeat what you have shown.

[@robertsonntag8333]

Interesting fact... You actually managed to get a fairly good looking frequency responce curve WITHOUT reversing the polarity on the tweeter. As a rule of thumb, every time you use a second order high- and lowpass filter you should reverse the polarity on one of the drivers. Right? However, it seems to work out just fine in this case. Love your vids, keep up the good work. Very educational stuff you're putting out. Cheers.

[@Bucefal76]

No it is not true. All depends of speakers positions at the baffle and speakers itself build details. To happen as you say both speakers had to be almost at the same place and have "sound center" in the same place. I think this is only possible with coaxial sparklers Additionally Kirby didn't check if his crossover keeps phase under control at all (no null revers checkek).

[@bensonrecordings764]

thanks a lot !

[@nathankilgore7061]

Hey Kirby, these videos got me started, thanks so much! I notice you didn’t address phase and I’m sure you left this out intentionally. It’s my understanding that a second order crossover will shift the low frequency phase by 180 degrees. Do you just switch the polarity of the woofer to accommodate this? And do you do anything to align the acoustic centers of the drivers?

[@westelaudio943]

In theory - yes. In practice - not always. Sometimes the phase response matches better when non-inverted, sometimes it doesn't match at all. Always check under angle too.

[@yewgray1154]

What is the difference between placing a resistor before or after a capacitor. As my understanding is that if i place a resistor before capacitor it will just make lower the sound. If i place a resistor after the capacitor it will change the impedance of the speaker to higher impedance and change the crossover point and also lower the sound. How about ur understanding?

Do you just believe the speaker specs, or do you test for actual readings from each speaker?

Other given specs may also not reveal the best results when testing.

If the market is there? These are free programs are they not? That basically means the programmer is likely making nothing off it. I really enjoy making UI (user interfaces), so if you already knew what you wanted I would love to work on a better interface that is more intuitive and much easier to work with.

so hey guys im trying this crossover thing but im a little confused, i have 2 4 ohm tweeters and 2 4 ohm woofers. now what impedance do i enter in the wizzard thing? i have read that you have to get the impedance of a single driver and divide it by the amount of drivers, does that apply to this asswell?

[@mikeables]

Hi Kirby. When choosing speakers for a build, I see speakers I think look good. Then I consider my listening practices. Mostly soft volumes but sometimes I like to crank the Emotiva mono blocks loud. I have noticed that some of the tweeters I am interested in are rated rather low. Should I be concerned about choosing a bass and mid rated for 400 watts and a tweeter rated for 60? Will the crossover software tell me how many watts are going to each speaker? Will I just blow tweeters when I crank them?

[@stucorbishley]

So the 'resistor value' of the inductor, is not a separate resistor like the diagram shows but rather the resistance of the inductor?

It is sum of DCR and possible external resistor in version 1.1. Version 2 has DCR parameter for coils.

[@walooss]

That is gonna be sounds terrible. First: the characteristics of both drivers don't sum properly, you have phase problem between 2k-4k. Second, you didn't consider Baffle Step, so there will be no bass. Same with tweeter - you didn't simulate baffle difraction. Third "notch filter on tweeter" - very useful thing when tweeter has tall impedence peak from Fs. I know that this film was all about: "how to do simple corssover with free software" but you have said: "this crossover looks good". No, you have to admit, final crossover is very far from good, it's hardly average. Flat frequency sum is not everything. merely I hope you understands me, english is not my first language.

[@francescodelia4069]

Walooss, your are right . phase response is not less important than magnitude response. furthermore, the positioning of woo and tw on the baffle is not specified and this has a big influence

[@adamwalters4921]

It really doesnt though and in this situation 99% of people will not hear a difference. At this point its literally a matter of if you have 40+ years of experience to hear the problem

[@cineaudiophile4465]

@@adamwalters4921 Er, no. Screwing up baffle step is *very* noticeable - it's just that a first timer won't understand what they're not hearing.

@CineAudioPhile Lol no it doesn't you cleary have no idea what your talking about

[@cineaudiophile4465]

@@kickass122112 Lol , Please tell me where in the video baffle step response as well as diffraction was addressed - both of which are crucial prior to doing *any* crossover simulations.

sir good day. can you video tutorial using 3 way speaker(crossover)

[@ryan8773]

So, I bought a behringer ECM8000 compression balanced mic, zoom 22 interface. ive downloaded the crossover software VituixCAD2. i also have live-lite music making software what software do I use to measure the speaker output into the mic, into the software ? 20-20k with graph ?

[@Tom_Losh]

Just a dumb question, Kirby, if one thinks that curve might sound a bit chesty or tubby, is there any SIMPLE way to reduce that low end bulge? (I'd play with the app myself, but even though I've used computers since 1969, I've never owned or seriously used Windows machine - UNIX and Mac here).

[@8bitbunny_VR]

Tom Losh hmm... Maybe a notch filter, or a dsp before the amp to save fiddling with components?

[@attainableaudio7130]

When the woofer gets in an enclosure there's something called baffle step, which basically means that the lower end will loose some power relative to the upper end... Depends on how large the front baffle of the enclosure is. So a lot of drivers which have a flat low end out of a box will actually be lacking in bass once in a bid which would require extra crossover components to correct. We'll just have to wait and see... Plus the hump looks a lot worse then it is.

[@Tom_Losh]

Actually, since it is going into a tuned port enclosure, the low-end response is already modified, but I do not know if the app has taken that into consideration or not. For some unknown reason I'm assuming the app is reflecting what it thinks the response will be *IN* that enclosure, hopefully not in free air or infinite baffle...

[@attainableaudio7130]

Tom Losh yeah its hard to tell for sure unless the measurements are made in the enclosure, but seeing as these measurement are from an infinant baffle, I'd say more likely the program does not take this into consideration... at least not this part of the program. I always make the enclosure then make my own measurements.

[@BostonMike68]

Hey Kirby how are you. I built these speaker's very similar to them with the same woofers. I ran the 4 ohms woofers in series for 8; ohms. I used a premade Dayton audio crossover at 3000 hz I don't if your crossover plan would work for 8 ohms if so I will buy the plans. I joined and pay a monthly fee for your channel just so maybe I can get some help because I did a beautiful job on them and I want them to sound the best they can. Thanks

[@zaccomusic]

amazing video hope you keep update :)

[@alvinquizon8785]

how do you use it for speakers with no FRD ZMA Files available

[@raygirard9237]

Loaded a driver, then the frd files but am still getting a flat line on the graphs. What needs to be done?

[@TaurusTrax69]

Are you using version 2? I ran into this same issue with this and installed 1.1 and it worked like it did in his video.

[@ryankern3049]

I ran into the same problem. Downloading 1.1 fixed it for me though. The new version must still have some glitches.

[@realsigsegv]

You need to go to the crossover section and connect the input to the speaker. After that the all line will show on the graph.

[@thethirdman225]

Hey Kirby, where did you get those lists of drivers? Did you have to download all of them from every manufacturer? Or is there a download link for them somewhere that I missed? Because I can't find them anywhere in VituixCAD.

[@Laser-rot]

take a picture? How about save the file (filename-001) then save again (filename-002) then if you need to go back just open the previous file.

[@audioerick]

this process is parallel to optimize line arrays for concerts.

[@clemmtec9506]

I have a focal crossover that was wired with five wires is there anyway I can send you the picture to tell me what I need to do ? thanks.

[@totoantoke]

I want to build a bluetooth Speaker with 2 Dayton PS95-8 and a Dayton RS150-8 powered by a TPA3116 Amp board. I'm not quite shure, if i need a crossover or if it's build in the Amp.

[@ledmk2]

Nice part
