So glad I found this video. I think you just designed my speakers.

[@BrunoAraujo-vs1lw]

I'm thinking the same xD would you update us with progress if you go ahead with the project?

[@RonSwanson24]

I don’t know how you don’t have more subs. You’re providing info for free that I’ve been trying to find forever. Keep up the good work!

[@Toid]

Thank You! I appreciate it!

Stupid you tube algorithm

[@poppawasarollinstoneboom9396]

You need to grind out videos 3 times a week for a year...

[@dam4274]

This is all over my head. There’s much work to be done prior to learning how to,operate this program. I don’t even have Excel. Never had to need it.

[@6LordMortus9]

2022 now and I'm watching this video in hopes to rebuild a crossover for my speakers... Interestingly enough, I just recently got a powered subwoofer from Parts Express, and my mids are (overpowered) Timpano's from PE as well :)

[@WiKiTWoNKa]

tHANK yOU sooooo mUCH, yOU aRE aWESOME!!!

[@sidneyalves1556]

congratulations my friend. how many meters of wire and how thick are each. thanks. Brazil

[@BryceandKyle]

I was going to use the Dayton Audio DC130BS-4 but it looks like the FRD file don't play nice with this spreadsheet. I'll probably just go with the Dayton Audio RS150-4. Thanks for the video!

[@Toid]

Scrapeddd Werkes you're welcome

[@linandy1]

Woah, that was awesome video !

[@Ryezn5057]

can you make a video using xsim or vituixcad instead.

[@roylikesitlikethat]

Nice presentation, thank you.

[@JadeB628]

I think in one of the previous videos you mentioned that a speaker driver is already limited by the frequencies of its "intended use". as an example. a midrange speaker has limited frequencies. same way as subwoofer also has limited frequencies. same with a tweeter, the only difference is a tweeter must be protected from low frequencies. from being damaged. so technically you can hook up a subwoofer with no crossover (without being worried about damage) that's from a safety point of view. keeping in mind that you did the wiring correctly so you don't damage your amp. I have a different question. but I wanted to make sure I understood you correctly. thanks

[@chrishernandez2490]

The problem with that is even though a specific driver "can" play up to a certain frequency, doesn't mean it should. The point of a crossover is to make sure it doesn't get to that borderline point of its "intended use" frequency because at that point the driver will be struggling and will not sound good at all.

[@Gioxtream]

HELLO THERE. I HAVE THE SCHEMATIC OR CROSSOVERS OF A SET OF BOOKSHELF SPEAKERS. I LOVE THEM VERY MUCH. I WAS WONDERING IF I CAN BUY ANOTHER SET TO MAKE A CENTER CHANEL SPEAKER. I WILL USE THE SAME CROSSOVER POINT ONLY ON THE TWEETER AND MID RANGE. BUT....I DO NOT KNOW IF I SHOULD LEAVE THE LOW FREQ COIL INTACT SINCE THAT THE CROSSOVER VALUE POINT WITH THE MID RANGE. I AM WONDERING IF BY JUST ADJUSTING THE CAPACITOR VALUE CAN I GET MY CENTER CHANNEL TO WORK. THANKS.

[@bryanbassett2110]

When I input units for target db levels, nothing changes on my charts. How do I fix this?

[@shubhangimalwankar4675]

Greetings !!! Have an amp of 135 Watts per channel output, what should be each driver output power (In Watts) for 3 ways speakers viz Tweeter, LF and HF watts. Thanks

[@joshynj3927]

Super

[@GOASTWRITTER]

Do you have a video on how to build very good Studio quality monitors. I want to make my own but anything with circuits is foreign to me.

[@danbalkey2580]

Can you or do you know someone that can build a crossover 3 way for pair hivi 3.1 speaker by Swann ?

[@ozyprima]

sir, is there available to make frd file by self? thanks

[@ramilrodriguez8340]

Hi. How can I get those speakers files? Or is there other way to load speakers specs to the program? Thanks.

[@davehennig9631]

Can I run a 8 ohm horn (tweeter) and 8 ohm dual cone mid with a 4 ohm woofer and build a suitable xover ?

[@LouMontana-wc7nr]

Can I put an 8omh tweeter in place of a 4omh tweeter?

[@HomeGr0an]

Where do you find the speaker files?

[@remyalexander3882]

What FRD file are you using? I try to load the ones provided from PE and they wont work.

[@tamojitsaha1128]

How do I design a crossover for the tweeter if it doesn't have any ZMA file? For example: Peerless BC25TG15-08

[@rickc2222]

How do you respond to the GR research guy saying sand cast resistors affect sound in a bad way? is he full of it?

[@Toid]

Great question. I would say that I haven't seen any tests that show an audible difference. However, I have seen a test where it does show that it is an inaudible difference. www.audiosciencereview.com/forum/index.php?threads/replace-resistor-by-low-inductance-resistor-is-it-audible.12162/

[@rickc2222]

@@Toid Yes i'd seen the forum thread you linked to but was not clear on their conclusion...would be awesome to see a blind test to see if listeners can hear any difference...because the charts dont always tell us everything (again according to GR research guy).

[@Toid]

@@rickc2222 definitely would make an interesting video. It would have to be a double blind test. In the above article they found the greatest variance to be 0.02dB, which is inaudible. Danny seems like a nice guy, I have never met him or talked to him, but he does have upsells on all of his products, keep that in mind. Not saying it isn't objective, but I haven't seen anything scientifically that would show a difference. Maybe if I can ever get enough people over, I'll try a double blind test.

[@fourthlayer]

I would consult Tom the crossover designer at madisound. He is an expert on Leap XOVER design. This is a very involved complex issue to speaker integration and design. What is seen here is fundamental design of a crossover. The vid is like here is how to play the guitar!!! Been doing this a long time and I don't know my shit!

[@Kcducttaper1]

I was wondering.... With that hump at ~4.7kHz. Could you just drop the mid's XO point by ~500Hz or so (or go to a higher order) since it's above the XO point and rolls off afterwards anyways? It might require a slightly lower tweeter XO point to make up the difference, but it looks like it should be able to handle it, I would think with less components.

[@Toid]

You could absolutely try that. That is the great thing about crossover design. There are plenty of ways to attack problem areas. :) :)

[@kuchbhi9758]

Then im using different ohms type driver in crossover like 8ohm tweeter 15watt and 40watt woofer speaker 4ohms so what ohms im calculate ?

[@Toid]

That is a great question. I actually did a video on that here: kzbin.info/www/bejne/g363eHefgc-mkJI

[@thelightbulbking4370]

What if you have multiple of one kind of driver? How do you enter it into the software?

[@Toid]

I detailed that here: kzbin.info/www/bejne/eZWplZeclKeMhrc&list=PL6hjpiCHZmIPx3itPeTt7zoSqNY20OQqV&index=8

[@crash7098]

So, according to your other impedance vid, if I'm wiring a 3 way 8 ohm speaker, I only need to worry about the largest woofer for the over all impedance? The smaller mid and tweeter can be whatever ohms as long as they are crossed over properly?

[@Toid]

Crash 709 assuming it's an actual three way and not a 2.1 then you should be fine

[@crash7098]

Awesome. I've been so hung up on trying to match the ohms of the drivers to equal an over all 8 ohms. Thanks!

[@Toid]

Crash 709 haha, we have all been there. Don't worry at all. I appreciate the support

[@crash7098]

Keep the vids coming. So much appreciated help for beginners like me!

[@remyalexander3882]

And i tried loading that woofer and i have nowhere near the spl yours does- is there a better way to get FRD besides PE provided ones- they dont work well for me

[@Toid]

Remy Alexander check this out. You have to delete few lines in the file. kzbin.info/www/bejne/fJ6Zpaagbrmjp9U

[@remyalexander3882]

Thanks, THis is my frist from scratch build, trying to do a TMM with a 8-10" woofer on the bottom so im trying to use your videos to help.

[@Toid]

Remy Alexander that sounds awesome! I can't wait to hear how they turn out!

[@remyalexander3882]

About to hit the ground running, just trying to figure out how to start the Xover design, should i wait till box built and if so how measure all together? I finally got PCD working and i got what i think is a "ok" Xover starting point. Rather not order all parts for the crossover for it to sound like garbage.

[@Toid]

If you want a good starting point, this is a good place to start. It may not be perfect, you will know more once you get the parts in and test it. Obviously, the best thing to do is to measure the speakers each individually in the enclosure. But if you do not have the testing equipment to do that, then you will want to do as many simulations to get it as good as you can. Make sure to check where your diffraction might be based off the size of your box. That will help tremendously.

[@drsauce2574]

Bro what could be wrong wit my crossover I bought a pre assembled crossover off parts express and hooked up my speakers and they play through the crossover but I still get vocals coming out of my sub

[@dakken74]

I'm having g the same issue, I think the crossover point for the bass is to high on mine so the woofer is getting some higher frequencies. I'm gonna try a crossover that has a lower crossover point for the woofer and see if that helps

[@drsauce2574]

dakken74 could be the problem my crossover point is 800hz for the sub

[@patrickrosington1174]

@@drsauce2574 800hz would be for a woofer. Not a sub woofer. A sub woofer is way lower. Usually 150hz and lower. I usually set mine 80hz. To 100hz. Never higher. 80hz is a really good point though

[@isaeagle4031]

Non min phase files, no offsets, no baffle effects. So the cross over is essentially worthless.

[@leongailberger7676]

Charles Morris why?

[@MickyMouseLimited]

This speakers files are like looking for a unicorn . It only make sense to buy a ready crossover. With out the speaker data the software is useless.
