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

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.

You are a brilliant, knowledgeable, quirky, and extremely likeable audio expert.
Respect, kid.

You could always make save points where you think you like the settings, just label the file after what you liked/disliked about it and then continue to work and make new file names. Lots of your own profiles! :)

Love this series of videos. Yes I've gotten alot out of them thank you.

[tomgoffnett]

I got a lot out of it. You do a great job explaining things and keeping it real. Thank you for sharing your knowledge.

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

[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?

[ryry]

I love the FDR parameters. LOL Great dude.

[onemandiy]

Great video series Kirby! I am learning a lot as I am getting ready to make my own build! I have forgotten so much!

[m.r.]

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.

Nice video! Real time playing around and having fun with software! That's exactly how it looks like when I do it and is fun to watch. You did a good job in explaining.
Unfortunately you forgot one thing and twisted a fact a little: 1) this software takes neither the baffle (step) nor the bass reflex enlosure into account. I asked Dayton Audio the other day how they measure their frequency response data. They replied that they mount all drivers onto an infinite baffle. A small baffle will change the responses and you lose the bass bump you liked. 2) As you say at 23:20 if you increase the value of the resistor you need a smaller cap but you need a bigger coil for the same frequency. But this is only true if the resistor is *after* the high pass. As you can see very clearly at 23:53 the position of the slope doesn't change if you change the resistor. If the resistor was between filter and driver the slope would move to left and right and also the steepness of the slope would change because crossover frequencies of coil and cap change in opposite directions.

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!

[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!!!

[derrickhaucke]

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.

[jordanhart]

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.

[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.

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.

[midoyoyo]

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 :)

Thank you for a very educational, informative video.
