Thanks! You are the only one on KZfaq who explains these things simply enough for a beginner to understand

Two things you didn't touch upon in this relatively simple crossover is the fact that with a 12dB x-over like this, the phase inverts 180 degrees between the woofer and tweeter, therefore most designs will reverse the polarity of the tweeter to compensate and bring the two drivers back in phase so they sound more "coherent" and produce better imaging among the L/R pair of speakers... And the other thing is that if you are going to spend the money on a Polypropylene capacitor for the woofer part of the circuit, then you should *definitely* ALSO be using that same type in the tweeter portion of the circuit, rather than the inferior sounding Electrolytic type as shown in this video!... If cost cutting is necessary because of budget I would use a Polypropylene cap in the tweeter and an electrolytic in the woofer circuit, especially considering that the larger uF values, (that you generally need for the woofer part), if using Poly caps can get very expensive, and the (generally lower) uF values used for the tweeter part can be easily obtained for a relatively inexpensive price... Also any sound quality degradation is noticed more in the tweeter high frequency detail, because the sound signal passes through the tweeter capacitor rather than being shunted to ground as in the woofer part. Also, the physical *size* of the capacitor(s) is another thing to consider, especially in small, tight enclosures... Large values of Poly caps get *very* BIG... Anyway, Yes, I'm sure you already know all of this stuff, (and maybe those details you are saving for a much more in depth, detailed video on how to design and build crossovers), but I thought I should mention it in passing... Maybe you could/should consider a more in depth video on crossovers?... Or if maybe you already have one? (As I'm sure a LOT of people out there could benefit from it!) I look forward to more of your videos!

Thank you so much Kirby, I've been looking for how to read and crossover high and low speakers.

DAWGGG!! PLEASE COME BACK MAN YOUR VIDEOS ARE FA FOR REAL MAN !!! HOPE YOURE DOING OKAY ON THIS QUARANTINE.

Awesome video Kirby! Around 2:48 you said using wires to hook up crossover components should not be done and that you would talk more about that later on. Not sure if I missed it later on in the video, but why shouldn't we wire components with speaker wires?? Does is have to do with wire gauge? Keep up the good work!

very simple and excellent explanation for a beginner to understand!!! Thanks a lot Kirby !!!

Nice explanation and love the style of your videos. Do you have a project on a battery/mains portable boombox type thing? thanks

Need a video for newbies like me. The jargon came fast and furious right out of the gate. You need to define everything you say. Thank you.

Absolutely brilliant job there man! I wish I had a lecturer showing stuff like you in college?

great video and very informative. love your channel! keep up the good work

Very Helpful tutorial that should Help a lot of aspiring DIYer to tackle crossover design! It looks hard, but once you wrap your head around it, it's actually fun! Thanks Kirby!!

I liked and subscribed in the first 2mins of this video - you're awesome! Thanks so much.

Thanks for the video! Recently bought the plans for your redwood Bluetooth speaker and can't wait for the components to get in so I can make it

Best and easy to understand about cross overs setup. I am your new subscriber from now on. Thanks for the video🖒

Quick question in your video with the "Best DIY Bluetooth Speaker Amp Board", would you need to add a crossover if you were connecting speakers to that speaker amp board?

Brilliant video, really well explained.

Very helpful. I'm a total newbie and this explained it in simple terms.

how do i determine the amount of wattage my crossover can handle

Thanks. Rebuilt a cross over for the first time of a KLH speaker and learned a lot. Sounds great but I’d like to do some tweaks thanks your video.

Great video, Kirby. The question I always run into when picking crossover components is around power handling. For instance, some resistors say they're good to 10W, others good to 20W, etc... The same kind of idea seems to apply with capacitors, but it shows up as voltage ratings and/or physical size like your tiny vs beefy caps in the video. How do you know what crossover parts to pick so that they'll handle your design loads?

I'm currently building your fawn kit, and I have a question: since the inductor and resistor are in parallel, do you connect the positive wire from the amp to one end of the inductor and resistor (with the other ends on the postive terminal of the woofer) or do you connect the positive cable directly to the woofer?

Hi Kirby what crossover you recommend for a 4 ohm 2 way boombox DIY project..I'm using 2 Dayton 6.5" Classic Woofers an 2 Dayton ND 1" tweeters all are 4 ohms?

Best video for newbies ever.. well done.

Do you ever use high pass filter for the bass driver, or is it not needed, only in small subwoofers as protection?

Great Video, learned much but Any video on how and what components to chose for the crossover? Capacitor and inductors values?

Like mining gold...I have tried to watch almost a hundred videos, and this one has what I wanted. Fantastic video. I would gladly pay for quality educational videos like this..

Well now that I understand this part, what do the numbers mean? What type of inductors, etc do I need for the speakers I'm using?

hey just wondering if you can do a walk through of how to build music producing monitors. I want to build my own monitors but the electrical and box size to go with the speakers is really hard to find good lessons on

Great video. How about the function of what each component does?

Very helpful, thank you!

great video. ive been looking for a video on this subject for years.... thanks man

Great Video. Thanks so much

Kirby i had a question if i was looking for a high pass filter that caps off at 65 hz what capacitor would that be if you know it would really help thanks

Very useful, thanks

Good stuff man, possible to get a video of you making one?

I was hoping that you would explain the function of the inductors and capacitors and explain why you chose those values of inductance/capacity... maybe a future video?

Hey I want to get an htc ten it has a 24 bit dac whats your thoughts ? please

Nice video :) Mabye you could make a video on how to design crossovers ?

Great video, I just wondered what is the best way to mount the crossover to the speaker, I dont think that is explained in the plans. Just bought one love it so far, can wait to get started!!

Amazing video, thank you for your time.

Another great video. I too would like to see an explanation of how you determine the inductance and capacitance. One point of contention, the symbol that you show for the capacitor on the schematic is for a non-polarized capacitor. The capacitors that you show in the circuit appear to be electrolytic and therefore have a positive and a negative lead.

Thanks for this video. Please explain how to connect two 15inch,LF, four 6.5inch, MF, and two or three HF tweeter speakers to a 3way crossover. Will you connect all speakers in series or parallel, what is the proper way.?

Can you also make a video about bass reflex?

How do I determine the ratings of capacitors and inductors to my speakers

Does the distance between speaker magnet and crossover afect the saund? Where should i put it in box?

In a first order filter, for example for a tweeter, does it matter if the attenuation by a resistor is put before or after the capacitor? Or is it the same?

Love your video's, they inspire me to try making my own speakers, thank you. What is/does the tattoo on your finger mean?

the rain in the background is actually soothing

is capacitor can be install in any different position? meaning is there positive or negative?

So I can use this crossover in my bookshelf speakers ?

thanks bro! helpful.

Superb explanation

Hey kirby. How will i setup a 2way speaker plus a tweeter with cross over build

I just finished a class in College about designing Low Pass Filters, Do you see cross over diagrams with LPFs that have more than 2 components or is that not very common for speakers?

Can you do a video explaining how inductors, capacitors and resistors work?

Hi. Can I connect my 2 instrumental speakers,1 mid and 1 tweeter in my 3 way crossover network? If yes how will I connect 2 ins speakers parallel or series? All speakers are rated 8 ohms and my amp is rated 8 ohms. Thanks for your help.

I'm glad you mentioned the rain Kirby. I live in California too up near Auburn and it's raining buckets. I thought what I was hearing was the rain outside my window and it was your audio track. You may have mentioned it, but I don't recall if you did ,regarding the caps illustrated in your video; electrolytic capacitors are like a battery and have polarity. They need to be hooked up taking polarity into account. I reckon that many this video's viewers are new to reading schematics and translating them into an actual layout. Polarity with electrolytic capacitors is an important concept to be learned about early. BTW, what's the crossover frequency in the example network? As a percentage, how much power translated to the drivers do you lose with that design?

Right on man, been tinkering.. got a little distracted with arduinos and raspberry stuff.. BUT, I'm getting close. I have beta test with a two single drivers.. it's ok.. not the 'best' so I'm thinking I need to do the crossover and add a tweeters to get better lows. Not expecting sub woofer sounds but something a little deeper. box tuning, and ported vs sealed is still somewhat of a mystery to me.

I would like to upgrade the components in my DCM KX-12 Loudspeakers but don't know what to buy. What would you suggest? Is it possible to make the woofer a subwoofer? (Passive)

nice video and thanks for share

Can we include ceramic resistor in that.? Thanks

so how do you determine what capacitor, coil, resistors you need? sorry for my dumb question but i am trying to understand the basics behind this, i can't find any videos that explain the concept behind the need of a crossover or how to build one in simple plain English everything is highly technical gibberish that i don't understand yet.

I would appreciate if you could explain BOSE 601's 3 terminal schematics cross overs (A+, B+, A-)

@3:55 Ugh! But that's what I need! My dad bought 2 8ohm, 3K low pass mono crossovers. And I can wire them in one of 2 ways. Dayton/Parts Express didn't send a diagram. There is an IN+, IN-, OUT+, OUT-. All I need to know is WHICH 2 go to the stereo, and which 2 go to the speaker. I've never worked with crossovers before. Thank you

nice and good explain sir

Wonderful crossover best vedio. Best 3way your crossover

but, if i have a 15w rms tweeter and a 30w rms sub, what is the wattage then

is the polarity of both tweeter and woofer inverted on the original diagram? seems like you changed it? tell me if im wrong because it seems to me... another question, how would you connect the crossover to the terminals, do you use a separate wires for the positive and negatives coming from terminals to the components?

What i needed for conpleting my elder kit in my 3d printed packman speaker i designed for this kit🤗 thanks.

awesome

im in all the way, thanks for all your help and website is also helpful, thanks again

hello can you help me i need pair crossover for speakers Yamaha Model S4115h please What is the alternative? or something similar the original crossover

What is the difference between the color of inductors that you used?

Kirby! Quick question. When building a system with two woofers and one tweeter do I need to make one crossover that uses high pass and low pass filter, then another low pass filter for the remaining woofer? It's one thing I've been confused on while reading your Elder Bluetooth Speaker plans. Thanks again, I've been waiting for a good video like this from a trusted source for a while.

Hi, i just noticed that you gave a value for capacitor. But i really want to know is. Or ishoul say, give also the specific spec for woofer and tweeter. I mean watts and ohms. And. Really want to know what size is the magnet wire, what is the dimension of your mould and how many turns for woofer and tweeter. Thank you for your effort on making this video. Its just that i have many questions.

How do I cap the frequency so it doesn’t go any higher for instance I want to do a bass / midbass two way crossover and don’t want midbass going over 500hz

Is the 6.8 capacitor that you show in the video non polarized? I noticed you didn't seem to pay much attention to its polarity (as well as the other capacitors in the chain) ?

why do you need an inductor for a tweeter? capacitor is enough to filter all the lows. or am i missing something?

After researching, you are correct. I am not an electrical engineer and was not aware of the specialized use It seems there are in crossover applications. I was taught that all electrolytic capacitors were polarized, and although wikipedia is not a solid source, it even lists "all electrolytic capacitors are polarized". There seems to even be a trick in cheap crossover circuits where they use two polarized electrolytic capacitors in series with opposing polarities to get a non-polarized electrolytic capacitor with half the capacitance. It is good to learn. ;)

What's the capacitor value and inductor turns and thin... Reply please

Hello sir I'm planning to build center speaker I have 100w@6ohms avr I want four 100w@6ohms speakers My question is... Is it possible to have one more 100w@6ohms for my tweeter dome? By the way, I'll fix it with passive crossover.. How many watts should my crossover? Thanks

or is a crossover like this only needed when you're using a seperate amp to power this in an enclosure?

My biggest doubt is how to wire the speakers to the crossover while sticking to the amp rated impedance. For example: lets say that my amp is rated at 8 ohms and my speaker has a 6 ohms woofer and a 4 ohms tweeter if I connect them in parallel it would give me 2.4 ohms, not good for the amp, and if I connect them in series it would give me 10 ohms (not sure if its ok for the amp or not because some places say it's ok to be a little higher and others says it's not). How would I resolve this?

hey un video sobre la función en físico para oír que tal suenan

Great video! Simple and clear! Just a note :) If I heard correctly, at 12:04 you said "crossover" instead of "inductors" :)

what is the purpose for crossover? what does it do for the sound? PLEASE EXPLAIN THIS.

It seems so easy the way you show it! Problem is I don't know stores who sell the components and I have had some hard time with online shopping so I won't risk it for the moment since I don't have much money on the spare.

How to find out the crosspoint? Thanxs

Hello sir How to make 4ohm 3way crossover ?

What are thre Values of the coil and capacitor ?

Is this parallel

Thank you, thank you, thank you. btw...dropped your channel's name as a "who sent me" on Parts Express.

How to make 500 x-over 3way? Thank you.

Your original 2-way crossover with the tweeter + going to ground was correct. With a 12 db/octave crossover, which is what you have, there is a 90 degree phase shift with each driver, only they shift the opposite directions such that at the crossover frequency they are 180 degrees out of phase and cancel out, leaving a dip in response at that point. By reversing the connection of the tweeter that problem is solved. With a 12 db/octave crossover for a 3-way speaker, the midrange is reversed in polarity, that is + to ground, - to the hot side, and the tweeter is wired + to +, - to -, just like the woofer.

Is that a Field Notes in your pocket?

That's informative and easy to understand, for me of course (the man, who speak in English very bad). Thanks so much :)

Why positive and negative always changes for Tweeter in all crossover circuits? Does it have any specific reason? Even in this diagram at the beginning, the positive lead was connected to negative line of the circuit and negative to positive. Someone, please clear my doubt.

enjoyed the more technical video

Weird... In Europe resistors are rectangle blocks symbols.
