You want to build a pair of speakers buty all you can fid is Schematic / Diagram? How do you read this? How do you make the crossover from the schematic / diagram? Today I am going to show you how to read this diagram . schematic and even show you how to build the Rule Break crossover (one of my own designs). When you are finished you should be able to take any DIY speaker schmatic and recreate your own crossover.

Awesome video… I’m glad ya went ahead and made this video public… you’re gonna have rule breakers being built left n right now 💪. I got caught up a little with work but I do have all the parts to build 3 and I have all summer off so I will be building them in July and I’ll send ya some pics to show finished products. Can’t wait 💪 🔈 🎶

I can’t wait! This is going to be Epic!

A few months ago, my uncle gave me a decent receiver/amp and some Infinity speakers. The amp supports 7.1 output. I have a couple SM-65 speakers that are pretty nice and a center channel that sucks. Initially, I started looking for HiFi speakers on Facebook marketplace, but then I stumbled on Toids. I got pretty obsessive pretty quickly. I am taking my second semester electrical engineering class and lab (I am a mechanical student, but we are required to take two semesters of electrical). I really struggled to get interested in EE, but speaker design was the thing that really got me invested. I haven't built anything yet, but my summer project is definitely a speaker build! I'm actually heading back to campus shortly to do a crossover lab. I found the timing of this upload highly serendipitous. TL;DR, Toids DIY Audio, you have been more valuable in getting me interested in electrical engineering and in improving my performance in my EE courses than any professor or TA thus far. Thank you for providing incredible and useful content!

Great video with solid advice.

@danrussell9357 Год назад

Thanks for using a real crossover as an example!

@Toid Год назад

You’re welcome. I was hoping that would be helpful.

@travis4619 День назад

Great video -- I'm building my 1st crossover and separating the network, highs / lows, so I can bi-amp. It can be confusing if you don't think about it in a separate network.

@travishall9398 Год назад

Thank you for the great instructions!

@mullinperformanceaudio5902 Год назад

Back in the 90's before the intenet, I would go to the library and read as many books as I could on sound and wiring. I can remember just staring at schematics like this trying to figure them out.

@Toid Год назад

Yeah, it’s definitely much easier once you understand how to read it.

@abbeybadero5455 4 месяца назад

@MFAddas Год назад

Could you please make a video on how to replace the crossover of an existing bookshelf speaker with an upgraded one? and also how to upgrade its binding posts.. much appreciated

@Jmanworks Год назад

Toid, I didn't see you mention this and maybe its a dumb question, but do you typically use a specific crossover board to hold all the components or just a piece of MDF? Or does it matter? I was thinking about 3D printing something.

@Bo-Ta- 7 месяцев назад

Why you doesn't use a ferrit ring with 10000 permeability? It's good and use little meters if wire ?

@lelordmarkquillopo6481 7 месяцев назад

is there a wattage required in choosing a coil and some other parts in making a diy crossover/dividing network? I have a 700watts subwoofer speaker and I want to try in making my own dividing network like you do sir. hope you'll enlighten me on how to make these and the parts that I need to make one. thanks!

@roanedog 8 месяцев назад

Great video! I have watched most of your videos and will probably buy some plans. Question: Do your plans include the parts we need to buy for the crossover?

@Toid 8 месяцев назад

Thank you! I a glad to hear it. as far as the plans go, yes they do include the parts you need to buy for the crossovers as well as the crossover diagrams. And if you need any help with that aspect of it, just let me know.

@-martintheengineer-7465 Год назад

👍👍

@chemicallust77 Год назад

The inductor on the low end makes sense and is very common in crossovers, but the inductor on the "tweeter" has me a bit curious...are you applying a high frequency filter on the tweeter to give it a warmer sound?...I don't know what the top end rolloff is on that, but I'm guessing your aim is to prevent unwanted high frequency outside its specs from going to it?

@Toid Год назад

That’s a typical second order high pass.

@Rmsky_ 7 месяцев назад

What brand of the speaker did he use😊

@N7-alpha Год назад

Are you accounting for ohm load when connecting the two woofers ?

@Toid Год назад

Yes. Although that’s not really the point of this video. The point of this video is just to show you how to read someone else’s schematic and then build it.

@christopherwilson6825 Год назад

Hey @Toid ok I put together this crossover and everything is correct. Now my question is? If I wanted to hook my speaker up to get the best sound Being as though I'm dealing with "RCA" , I can use a speakon to connect to the amplifier do I have to get another RCA to speak on connector on the other end of the RCA let's say for example I'm hooking up a subwoofer One is the speak on to RCA three-pin The other end would be RCA. For to hook up to the speaker hopefully I'm making sense. Do I have to get a reversal RCA to speakon to get the better sound.? Apologize for this long question. But thank you and this is actually for anybody to answer in the community. Thank you

@brianwood5220 Год назад

I have a question. On the first part of the video you used an Air Coil Inductor, But in the second you used an Iron Core Inductor. Why and what is the benefit of either?

@Toid Год назад

There is a few benefits, but in general when you are using an inductor for a high pass, you will use an air core. On a low pass, you will use a solid core.

@brianwood5220 Год назад

@@Toid Thanks for taking the time to answer me. It was probably a stupid question.

@andrewmitchell2666 Год назад

What is the purpose for the resistor for ?

@RioGrande3004 Год назад

What are the values on all those parts?

@jimthvac100 Год назад

Another question, When you are designing crossovers using XSIM do you just use the FRD and ZMA files from the driver manufacture or do you actually put the drivers in your baffle and take a measurement of each driver and use that actual graph to load into XSIM? Seems if you used your actual measured graph you would not need to figure in a baffle compensation circuit?

@Toid Год назад

That’s a great question. The way that I do this is I do take measurements directly from the drivers in the baffle. I take a measurement of just a tweeter, a measurement of just a woofer, and then a measurement of both of them wired in parallel. Once you do this, you can import the information into XM and also figure out your Z offset which will help you get phase alignment when your design in the crossover. I went over there in my Xsim tips and tricks video.

@jimthvac100 Год назад

@@Toid Thank you, I will look for that video, I need to understand Z offset and phase alignment a little better. I have been designing crossovers using XSIM and factory FRD files but really they would be different if I used actual measured graphs off the baffles I would be using, makes since.

@jimthvac100 Год назад

Curious why R1 is after your cap and inductor and not before? seems like your impedance would be better if the resistor was before that inductor so it is not loading the amplifier as much. I understand an LPAD would be after but this is no LPAD.

@jimthvac100 Год назад

@@Toid Thank you Toid! I just watched that video good stuff I understand why you may of used that resistor there now. I love the science behind crossover design. I have made about 50 crossover designs using XSIM and FRD' etc... I have made several FRD's and ZMA,s using FP Graph tracer. love it lol.

Wht a messy way to explain it and even worse doing !

@Toid Год назад

Really? What would you have done differently?

@zeldatearsofthekingdom3577 Год назад

Literally a break down of step by step instructions on how to build a crossover and you say it’s messy??? Only way it could have been better would be to show the assembly piece by piece as well… besides that… it’s a great tutorial… now your channel. Now that’s a “mess” 👍 @toidsdiyaudio keep it up man… solid video 👍

@philipperostin Год назад

@@Toid I would have just follow the schematic and not fly over explanations that dont make any sense and have no continuity whatsoever You dont even show the final result !

@Toid Год назад

@@philipperostin I am very confused. I did show the final result. And I started by explaining what all the parts on the schematic were and then showed you how to read it. It does you no good if you don’t understand how to read the schematic. It seems as if you’re in the minority, so this video must not be for you. Hopefully you can find one that helps you out.
