That is a fun thing to read on and do. I have spent way to much time on the parts express speaker builder forum in years past. Well done sir, I always enjoy your videos.
I'm not an audiophile. In fact I think I'm a little tone deaf. But I have a question: Why do some speakers have holes in them, and are hollow inside, and this build included filling the hollow with fiberglass? Are those two different types of speakers, or some alternative setup that produces a different sound, or something?
Interesting project! From my past experience building speaker cabinets and crossover coils, I suggest: 1. Make the coil core from 2 opposing wood wedges - it'll make removal much easier. 2. Never place 2 coils in a crossover in the same plane - they must be at right angles to reduce cross-talk.
Howdy. I'm with you. And more: 3. Always use a wire gauge of 1,5 mm diameter or even heavier for the coils. Thin wires reduce the damping capability of the amplifier. 4. The cap.s should be 3 or more smaller ones in parallel. This reduces the cap. lead impedance. Regards.
John you are amazing, not only as a wood worker but an all around person with great diversified abilities, not to mention good old fashioned common sense. Your commentary is HILARIOUS!!!!!!!!!!! Please do not give this up!!!!!!!!

@elneno427 What'd the point of watching a DIY crossover build video if you're suggesting that we should buy an off the shelf "one sound fits all" boxed crossover off of Amazon??? Bruh... come on man drink some coffee.
I appreciate the work this guy does. He can't help it (nor can I...) but his explanations just put me to sleep. When I wake up, I rewind the video and I fall asleep again. And it's all information I want to digest! Oh well. I'm sure it's just me. Live long and prosper!
John, I have hand wound hundreds of toroids/inductors for home built radios (mostly amateur radio). I typically heat my soldering iron up as high as it goes and use a blob of solder to burn off the enamel and tin the wire all at the same time. Works for me.
Given that my cell phone has never sounded so good, hooked up to a good system and in a proper room (not your workshop for a laundry list if reasons we wont go into in this comment) that speaker sounds amazing !! You've made me want to go down the audiophile rabbit hole again !
A hole for rabbits? Why rabbits? And could it be a, "Tube"- for the rabbits? And why use rabbit in it's "plural" form? Just exactly how many rabbits? All of them at once or just slowly, "One at a time"? Will the rabbit's be, "Injured", in any way? Should I feed them first or wait? What if I "accidently", fed them first. But now three of them are just too fat to fit in the, hole/tube/particle accelerator, plasma inductance, rail aperture? What then? I need more information. You "audiophile", types are just a little too odd for me!
Great build! Once I was building my speakers way back in time I got the advice to orientate the inductors 90 degree to each other to avoid the magnetic fields to interact too much. Probably nit picking but did not take any extra time or cost so why not.
John, I don't know about others, but when you got to the point of the music playing, on my Bose Quiet Comfort 135 headphones, which I use to listen to YT videos, it was quite impressive. I can only imagine the sound that you were hearing.
Most excellent! You don't need me to tell you how good a job you did! Lexan or plexi is best because 1) It looks good, and 2) it is non-conductive and will not absorb moisture. I made two or three large networks almost EXACTLY like this in 1997 for car audio installs. I still have a 20 pound box full of Axon, Solen, and SCR PP and PS 600V capacitors, Solen Litz wound and standard wound 12ga and 14ga inductors, and numerous non-inductive wirewound 0.5% axial resistors with 16ga tinned OF copper leads. Love your projects!
The video is good, the article is excellent. I would have assumed a ferrite core improved induction, but the distortion makes sense. Inspirational. Thank you.
Wow, John! You can tell those speakers sound f’n killer, even after YT has compressed the hell outta the original audio signal. Normally, you can get a vague gist of what spkrs sound like after YT has basically destroyed the quality of sound, but it’s quite obvious you’ve built yourself an amazing pair of spkrs. Even listening to them through a shitty pair of computer spkrs I hook up to my iPad, they sound great! Well done, dude! Very well done...
Such a nice and clean job congratulations. Thank you for the vídeo and share It . My English Is not good ,but you speak such relaxed that I understood everthing you said thank you from México.!!
*"Getting better with practice, just when the project is all done"* is now a phrase ready to adorn the wall of my workshop alongside with, _"I said I'll do it. You don't have to remind me every six months", "Appart from sawdust, I also make some things"_ and _"If hitting it with a hammer is not effective, use a bigger hammer."_
Great video, thanks John. Thanks for replying to my concern about heat build up. I didn't realize that the components run cold, or at least cool. Good to know, thanks.
I used R20 on the first speaker I built. Actually, I didn't have any woodworking tools, so I got some used boxes. Anyway, they were originally very boomy, but when I added the R20 the bass tight end up nicely and got punchier. So it works well in the cheap!
In reading about crossovers I too was impressed with what I read about 2nd order Linkwitz Riley, but eventually found multiple sources to say that while 2nd orders look good on paper, more components means more external affect on the audio signal and that the 1st order is usually the best and series is preferred over parallel. Pretty much every audiophile I spoke to about crossovers said that in today's world, digital crossover is the way to go. Digital crossover means no passive components in the audio stream, so I take this to reinforce the idea that the less passive components you use, the better. Also the cap on the tweeter in a passive crossover needs to be bypassed to allow the higher frequencies to pass more easily. Use a 0.01uF cap, and the cornell dubilier 940c 3000vdc is said to be excellent for this purpose.
Id like to see how they measure. And to know how the crossover was conceived ? How did you find the right cross over point? How did you come up with the component values to be used? How much baffle step compensation? How does tweeter and woofer match in SPL? i noticed no dampening resistors. If baffle step compensated? most often tweeter will be 3 - 4 db. higher then most woofers. If no baffle step compensation, bass level will be very little and the tonal balance very bright. have you considered getting a U-Mik 1 measurement mic. (quite cheap) and install REW on your computer (its free) so you can measure what really happens? and a LCR meter, all these things are a relative small investment that will give huge improvements in sound for DIY build.
I don't think the coils should be aligned like that because the fields will interfere with each other. I have seen many kits doing it that way but have been advised to do them at 90 deg and not pointing an axis at the other coil. I would also solder all internal wiring because crimps are prone to corrosion and developing high impedance which is particularly bad for speaker performance due to the drivers low load impedance. In fact, it's the main reason for deteriorating performance over time. If you must do crimps, paint contact surfaces with deoxit conditioner before crimping to seal out air as long as possible. I would also stand the caps up off the board and apart so they can dissipate heat better. That should keep them in spec longer.
With the ring connectors I like to take the plastic portion off. Tin the speaker wire like you did. Insert the wire into the ring connector and somewhat crip it then solder the wire to the ring connector as well, leaving you with a very reliable connection (You can heat shrink it after).
@@timburton4437 Guess you haven't come across too many Xovers. They're used to stem the flow of electricity and to balance sound levels. Part of an LR design.
Loved the video, John...especially the creative editing you incorporated. As far as I can tell from my crappy phone, the speakers sound as great as they look!
Great vid. 👍 As always illustrates how during this Covid 19 stay at home what do I do scenario can be beneficial in so many ways to taking time out and with family as well, to build some amazing (OR renovate ) gear. Sound is very relative and I've built all my own home systems including an awesome 7 channel surround system for peanuts using stored in the loft over the years, parts and pieces. I always remember back in the 70s having a Phillips cassette deck and adding an extension speaker mod (No additional amplifier) to it and the sound improvement / output was astonishing, which led me over the years to experiment with changing the sound et to suit my own preferences. Adding tone circuits is easier than most think which can drastically improve sound output 👀👍
oh man, you should release a sound file of what you were saying when trying to remove the coil from the jig. i bet it'll keep my ears warm through out the cold, cold winter :)
Very nicely done video and great work. I love audio and woodworking too. I’ve done DoD/DoE and related contracting, as well as commercial consulting for decades- from Hz to THz as some say. Anyway, whether breadboarding or doing design-deployment, don’t mix metals or EVER use stainless or plate in any critical signal paths. Don’t bind with it, don’t bridge with it, don’t run with it. There are not insignificant effects to you signal within the audible frequency range and it only gets worse beyond. Solder, or use another copper-to-copper binding method. You are not using low-end components, so don’t use low-end methods.
Ever consider how the drivers permanent magnets affect the air core inductance? The drivers are located pretty close to the xo. You can download Tesla Bot to measure the magnetic field. I played around a bit but never measured the coil inductance with the driver magnet near it.
As always, your work is inspiring. I have to toot my own horn a little. I made my very first successful solder the other day. I can weld with the big boys but I can't solder to save my life, lol.
The insulation was a neat trick, not something I would have thought of. Thanks for this series, inspiring me to give this a try. I needed a project to practice my soldering on anyway.
I have always like those open cell foam "bed toppers". You can get them cheap at most big box department stores, and if left loosely folded so they are not crushed, they work extremely well.
Those speakers look great John but I have no idea what you did in this video. However, looks like first class electronic work going on & the speaker(s) sound terrific!
Shouldn't the coils be aligned 90 degrees apart to not interfere with each others inductance? As speaker performance is very impedance sensitive, I would recommend soldering all internal wiring rather than clamping and screwing, just to reduce oxidation over time. Failing this, some Deoxit conditioner on these pressure connections would help maintain low impedance over time. Good to see people still doing DIY speakers though. The perspex XO mounts looks neat too, pity they are on the inside.
Fun project. There is very good free speaker design software available now. If you are thinking of doing a project like this and want to go beyond building one of the great kits available at places like Parts Express or Madisound. A program called boxsim available on the Visaton website lets you simulate the response for different box sizes, tuning, crossover changes. boxsim has library of drivers to chose from, or you can load parameters of other drivers manually in to a project. Another program Xsim also works well, but doesn't have a library of drivers, but you can load files from manufacturer web sites or measure yourself.
Thanks for this Sir, Kindly advise, I have in my car a a mono block dedicated to the sub and another 6 channel amp dedicated to all other midrange and tweeters and lastly a an equalizer.I however do not still appreciate 20-30hz wavy/ air bass, can an aftermarket crossover cancel off the punchy bass and give me only the wavy bass of 20-30hz to the sub. (All equipment and speakers I have are from pioneer high end)
I love the speaker build. I just finished building your table saw fence from the plans I purchased. It's the best fence I've ever had!! Thanks and keep it up!
I was knocking out some calculations building a speaker for the last few days, using the phones calc and cursing that i cant find any of my many calculators.
Really appreciate this video and the diffuser video as well. Would love to see you continue doing more audio builds every now and then. An isolation platform would be cool to see. Or a fancy turntable plinth. Keep up the great work!
Shouldn't you tin the copper after its screwed to the connector because it would add impedance going through the Sauder which isn't as conductive as copper. Wouldn't it act as a speed bump to the electricity or is it just a negligence impudence? I'm not trying to be a troll I'm really asking because I don't know. I'm wondering which way is better because I don't know.
Hey john any plans to experiment with one of the coils sitting perpendicular from the others. From my reading coils on the same plane like that in close proximity may exhibit mutual inductance.
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?
would you need to do anything different if you're making outdoor speakers? They wouldn't be directly exposed to the elements, thinking of speakers under a porch roof.
Great video. Thanks John. I appreciate you judicial use of hot glue and the humour associated with it. Also, I have the same receiver. Plus, I assume that you were doing “The Dance of Joy” at the end.
Hi John. Thanks for the video. Many years ago I built a set of speakers. Two tweeters, two mid range and two bass speakers in each speaker. I know very little about electronics and got someone else to build crossovers for the speakers for me. Unfortunately the crossovers resulted in the mid range speakers dominating. Would you be able to inform me what components I should use to build new crossovers where the tweeters and more so the bass speakers would dominate? Thanks.
boss question, 3 speakers subwoofer ,instrumental and tweeter in one box, each one 350WATTS. how many WATTS is the 3 WAY dividing network that can be used? thanks and more power

(All equipment and speakers I have are from pioneer high end)
Very nice and educational video.
Get a mini butane torch! Super useful also for heat-shrinking electronics, much faster than a lighter!
I've burned too many shrink boots, so I use a heat gun now, lol.
Well I must say they sound beautiful. Vibrant and full bodied. Get ready for someone to tell me I can't tell via YT😂
Excellent - Excellent speaker site, well done John - and no one cares about the hot glue in the box - sound is the importance here.... Great JOB!!!!
Very nice! Now speaker complete and sound is impressive! Thank you for video!
I love the speaker build. I just finished building your table saw fence from the plans I purchased. It's the best fence I've ever had!! Thanks and keep it up!
the speakers turned out nice but this part of the project went over my head
I was knocking out some calculations building a speaker for the last few days, using the phones calc and cursing that i cant find any of my many calculators.
Really appreciate this video and the diffuser video as well. Would love to see you continue doing more audio builds every now and then. An isolation platform would be cool to see. Or a fancy turntable plinth. Keep up the great work!
Those look awesome. Great work
Sounds real good.
I laughed because your old yamaha receiver is the exact one i still use today ! :) gj !
Great job on the speakers. What is the song you used to test your speaker? Thank You.
Sounds very nice
Sounds killer.
I did a madisound kit build with very similar vifa drivers back in 2000. It was pretty good, especially for a few bucks
Looks and sounds great!
Nice work john!!
Excellent videos bro
Nice work , clean and tidy looking crossover.
Please share the details of capacitors used and connection diagram.
Regards
Shouldn't you tin the copper after its screwed to the connector because it would add impedance going through the Sauder which isn't as conductive as copper. Wouldn't it act as a speed bump to the electricity or is it just a negligence impudence? I'm not trying to be a troll I'm really asking because I don't know. I'm wondering which way is better because I don't know.
Nice and clean
Impressive sound. I may try your crossover for some speakers I have in my shop. Some separation of highs and lows would improve them. Good job Sir.
Hey john any plans to experiment with one of the coils sitting perpendicular from the others. From my reading coils on the same plane like that in close proximity may exhibit mutual inductance.
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?
would you need to do anything different if you're making outdoor speakers? They wouldn't be directly exposed to the elements, thinking of speakers under a porch roof.
I like, that you left some unsuccessful stuff in (clear 1/4" acrylic), because life isn't a polished Instagram post.
so clean 😍
Great video. Thanks John. I appreciate you judicial use of hot glue and the humour associated with it. Also, I have the same receiver. Plus, I assume that you were doing “The Dance of Joy” at the end.
Hi John. Thanks for the video. Many years ago I built a set of speakers. Two tweeters, two mid range and two bass speakers in each speaker. I know very little about electronics and got someone else to build crossovers for the speakers for me. Unfortunately the crossovers resulted in the mid range speakers dominating. Would you be able to inform me what components I should use to build new crossovers where the tweeters and more so the bass speakers would dominate? Thanks.
boss question,
3 speakers subwoofer ,instrumental and tweeter in one box, each one 350WATTS.
how many WATTS is the 3 WAY dividing network that can be used?
thanks and more power
