So interesting. Reminds me of trying to design an RIAA preamp many many years ago. Interested to see the maths behind this and wonder if jogs my memory! Thanks
@@KissAnalog I'm sorry but you seemed to avoid my main question. Is it a cheap crossover or not. It can't be that much for the price the asking. I actually googled "what do cheap crossover's in home stereo speakers sound like. Can't find the answer. If you buy a pair of lower end speakers Will they come with lesser quality crossover's?
@@KissAnalog PS The more expensive the speakers the better quality crossover's? The cheaper the speakers the cheaper the crossover's? Oh and I wish I could have understood what you were doing. Just a lamen win it comes to electronics. It always amazed me though.
@@jefferyrichardson1348 Danny Ritchie is a long time speaker designer who owns GR Research out of Texas. He has a YT channel where he redesigns and mods existing speakers. The sad fact is, even speakers costing thousands of dollars each will have cheap internal components. And it really can degrade the sound. Worse yet, the engineering in even high end speakers is hit and miss. Richie often finds speakers with horribly designed crossovers and usually poor parts quality. He will even compare speakers costing thousands of dollars to those costing 10X less, just so you can see how spotty the engineering is. He will completely redesign the crossover while using the same drivers. He then sells the parts and instructions on how to upgrade your own. He has redesigned hundreds of speakers, and he's a master at it. I can tell just by looking at it, that this crossover has some problems. Sand cast resistors are terrible for signal degradation, and the way the coils and capacitors are arranged on the board allows them to interfere with each other, further degrading the signal. The board layout was obviously meant to minimize real estate, and that nearly always comes with sound quality compromises. Those coils are air core, which is a ton better than iron core inductors. But they're cheap, light gauge wire inductors which introduces unwanted resistance in the signal path. And not all copper is the same. Your average copper wire has more resistance than high purity copper. These little things add up. Many speaker brands don't expect you to ever look inside. So they stuff them full of the cheapest junk they can find to maximize profits. High end brands are not immune to this practice. Lately, Richie has been hammering Klipsh. Not because he hates Klipsh, but people keep sending him their Klipsh speakers because they don't like the way they sound. He has done miracles on them, but he has to question what the engineers were doing with such terrible original design.
Bought those crossovers a while back. Just gotten around to the speaker build and it was a pleasant surprise to see those exact crossovers on your channel. I was hesitant building my own crossovers so bought these ones. Your video was all the confidence boost I needed to go right ahead with my build. Subscribed!
I just used these in a speaker build and sound great. I'm happy....I'm sure it's not as good as having crossovers made for specific speakers and enclosure combinations but working very well for me
Ready-made crossovers are not my way to do things because your drivers have to be precisely the right impedence to match the x-over design. Not only the parts (coils, caps and resistors)are of poor quality but even the implementation on the small board will induce cross-talk between inductors even if they are placed at 90° from each other. I know making your own x-over may be time consuming because you do have to do extensive tests and listening sessions to make sure your design sound right, but in the end, the result might amaze you. Thanks anyway for the hard work of making this video!
Eddy shouldn’t you terminate the filters with the speaker impedance ? I am a ham radio Amateur and In HF measurements always terminate the output with 50 ohms Never made a bode plot Now I can ,thanks to this great GWInstek Scope , thanks for this Video and explanation
Bert van Lelieveld Yes, you are right! I should have terminated the two channels that I was not monitoring;) I can’t wait to try this! Any other ideas for a second video on this?
@@KissAnalog Would like to see how it behaves with real word drivers as a load. other than that . A phenomenal video and real enlightening as to what is really going on as opposed to a spec sheet.
I wonder if this would be a good cross over for my HIVI 3 a bookshelf speaker that was made from kit. kit was missing crossovers. ceramic i thought were the cheapest of the cheapest ?
Thanks for asking Dan! It's hard to say it would be optimized for that speaker, but it does have crossover frequencies that are pretty generally placed well;) What do you mean ceramic, the resistors or capacitors? Ceramic resistors are very good I think. Ceramic capacitors are very good caps as well, but poly might be better for audio applications.
thanks for infor . i really dont know much about crossover parts. i just wanted to make a crossover with the best oarts for these speakers. caps and and also the resister. From what i been told that lower end speaker put the cheapest parts for the crossover. Dayton audio are cheap ? would know anyone that can build my crossover for these HIVI i do have the the spec kit that are stock. but there a upgrade to change some spec. call a perfectionist upgrade by scott from Mideest auto club
I have those exact same crossovers in a bose 501 IV speakers. Not only did I add these crossovers but I replaced the sub and added midrange and new tweeters. My goodness what a difference especially in the low end.
Great video! I have a question regarding those resonant spikes... When actually using this crossover on a set of drivers wouldn't some of those resonances cancel out because of the phase? I don't mean perfect cancellation but at least some degree of attenuation. I ask this because I noticed, for example, that the woofer resonance at about 800Hz seemed to have the polarity more or less reversed from the 800Hz from the midband crossover. Again, not actually the inverse polarity but seemingly close enough for there to be some level cancellation. Thanks in advance!
Thanks for your feedback! I have a playlist of videos on speaker crossovers. Here's a link to a video that might answer your questions: ruclips.net/video/kawTphp-sTk/видео.html
I have found that you need to load all sections of a passive crossover to get accurate data. I was testing one with just the section I was testing terminated, and the results were different than when all sections were terminated. Really like your videos.
It's not often you see crossover testing which is great to see. I would have hoped you'd connect all the outputs to the one channel ant see how they interact and perhaps cancel and add together. It may have calmed those resonant peaks.
Hello, excuse my English, I give an example, in my case I have some large speakers and the technical specifications were lost, they are Japanese from the 70s similar to Sansui, if I wanted to place these crossovers, my ignorance confuses me the frequency response of the Amplifier It must be according to the one of the baffles right? But what about the baffles is governed by the frequency response of the crossover? here comes my confusion, because if the crossover starts at more Hz those frequencies are filtered and therefore it will be heard horrible ?, thanks if you can clarify this doubt is appreciated.
If you send the wrong frequencies to a speaker it might also damage that speaker as well as not sound great. But speakers and crossovers are designed similar for the same type. So, a 3 way will be all designed with similar crossover - but really different compared to a 2 way.
@@KissAnalog It is confusing, I have seen people buy amplifiers with a certain frequency range and loudspeakers well above this range, for me with what little I know of the subject is a gross error, and that of damaging them, it scares a little because we must trust the crossover we buy is well designed, thanks for the explanation.
That's a great question! I plan to do a video to show how to modify one to get what you want. I think you are fine to use a 3 way and not use the woofer - if that works for you. What crossover frequencies do you want as an ideal?
Yes Seraph, you are right:) I will post a follow up video that I think will show much better bode plots;) Thanks for this great insight. Let me now if there’s anything you would like to see covered.
@@KissAnalog for the LM3886 one, can you try replacing the LM3886TF with the LM3886T version that has a cooper backplate, so you can get better result on the thermal side, and also, can you test the capacitance multiplier power supply designed by Mr Evil, i heard it smooth-out any kind of power supply ripple to almost nothing, mrevil.asvachin.eu/amp/amp4/sub/psu2/

Thanks for the great question! I think if your speaker is a 3 way, then this might not be a bad product to try. It is true that some speakers are tuned very carefully with the crossover, where I think many are not that carefully tuned. What did you mean about the wire going through the top or bottom?

How do we know if these are good for my speaker I have a HIVI 3 way kit that need crossover built for them. Just don’t know if these are a good buy for my speakers. I didn’t want anything cheap. I have seen I can buy crossover parts and build my self but price is leased 100 plus budget of 200 for a set. How do these match your speakers ????? Is my real question
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
Great question! Is the tweeter also rated at 350 Watts? It depends on how the 3 way is spec'd but I'd think a 350 Watt crossover would work but you would have to verify what the power actually is rated at each channel output. But 350 Watts in a tweeter is nuts, or even a mid-range;)
You can measure all you want but on a HT receiver or low res system it does not have to sound much better . If your system is capable of delivering high resolution and transparent sound you got to listen to the way each part influence the sound , with ear , yes with ears
Yes, the engineers that design and produce the low res and High res measure to be sure that they are hitting their perspective targets. It is up to us to check their measurements - and then finally listen to see if it is what we like - but measurements should always come first.
@@KissAnalog tonal qualities , harmonics , soundstaging and many other aspects must be heard and that is where quality of the parts plays huge role and it must be heard as perfect measurements can not show these qualities ....
I just picked up some old 70's B-I-C Venturi Formula 4 speakers and want to update the capacitors. Two of them are 16uf 50v and 4.7uf 50v. Do you think i will have a problem using 15uf 250v and 4.7 250V?
I'm in need of a crossover for a build those crossover frequencies are about where I'm wanting it, but I need something that will handle 2x12" 450w driver's in the bass section. Anyone know where I can get such a crossover?
Can somebody buy this crossover for a Pioneer CS G305 three-way 12-inch speaker and that sound good or would it have to be matched up with a certain kind of speaker
@@KissAnalog I did take pictures there wasn't nothing inside their only close to the tweeters in the mid-range a little cap. off the connector in the back to the subwoofer there was nothing crazy

You need to connect 8 ohm loads to the speaker ports before you measure the crossover. I didn't see you add the loads and you will get a very different result.
Thanks for the question. I'm having a hard time keeping up so I'm responding to subscribers first;) This depends on what the core is, do you mean for an air core?
I liked your video enough to run with these 3 ways for a build of my own. But I am sorry that I had not finished watching before I placed my order. to use your link for you to get the amazon credit. But I did give you a thumbs up and subscribed to your channel.
@@KissAnalog Hi Eddie, I'm just going with the flow of your videos, it will be interesting to see it loaded as Bert mentioned. I believe that it may have something to do with reflections ? ATB Adam
You could simply use 2 of the 3 outputs like maybe the tweeter and mid. But, we could see how you could use the parts of a 3 way to make a 2 way. I'll do another video to talk about this. Thanks for the feedback!
Hi ,Just received the same but for 2 way divider model AS-23C , they have good quality parts , at least i believe hhh will see how they perform ! i am planing to replaced the cheap crossover i have in my bookshelf speakers with them. Thank you
Hello Kiss Analog . I wrote this question to you with the help of Google translate. I have a Dali Oberon 5 tower speaker. 2-way and 3-driver. It has 1 tweeter and 2 basses. at 6 ohms. Can I do this 3 way with Kasun 33C? The speaker bass port is at the back and close to the wall. I'm getting too much bass. I want to use one of the bass drivers as a midrange.
Eddy I am also interested of filters adding any Distorsion And which parts are responsible iff so I am in a Dutch audio community And there are realy nice people I am building for fun tube amps ( i like the sound ) and I get a lot of help ! But tube amps have very heavy mains transformer Nobody in this community ( dare or play save ) trying a SMPS That’s wat I wanted to try out rebuilding a old ATX computer power supply in the near future Like to know if you can , or willing to setup up a PP tube amp with a smps And measure if there is a different in audio distorsie with a lineair power supply or SMPS Let shake up this pre judgment a little 😀
Bert van Lelieveld Hi Bert, the distortion issue I think is a real thing. I’m sure the members of your Audio community would agree, and are really concerned. I’ll try to talk about that in the follow up video on this. I’m sure that this will be something that will develop over time and hopefully I can help work out these issues. This will be fun! I am a purest to a point, but I also think there are preconceived biases to the types of power supplies;) Let’s look into this and see what we find. These are the questions that I have had as well!
Thanks for the review in terms a person like me almost understands, I hoping to build my own 3way speakers using these crossovers, great coincidence as this was a random off ebay. Cheers from Australia
I don't think a spectrum offers anything better in regards to Bode Plots. A spectrum requires a tracking generator to do Bode plots too. That's where these new scopes that can do Bode plots are so awesome. Thanks - that was a great question!
Lets restart, after watching your second video, i realize that you are on a right track, im sorry for going harsh on you... i would like to see more tests with actual speakers, and maybe comparing it with another different set of speakers, just to show people how big difference it can be.
Sorry you didn’t like it. Can you tell me what is incorrect? As an electrical engineer with decades of experience and who was the head of an electronics program for 3 years at a community college, I’d like to continue learning. So, if you don’t mind, what did I have wrong?
@@KissAnalog yep, this is the common problem with engineers....no offense... But audio is more than math... You measure crossover without dedicated speakers... Attach them and you will see a big difference in your measurements, also you should measure interference between those parts... Also you need to measure phase difference after that cutting, because after the frequency goes down, also the phase moves away and you get low volume but still active out of phase sound from that speaker, 12 db is nothing special, its steap cutoff but there are a ton of music within that first 12db cutoff that is, at some degree out of phase, and you can hear that, and you gonna have a bad unrealistic stereo image...
Also as a engineer, you should know that capacitors and coils have their + and - , when outer level of coil is connected to the Amp - that means its grounded, and layers below are shealded from interference (positive end)... No matter if its a electrolytic cap or ceramic... Or whatever...they all have inner and outer layer.... Outerlayer is always (minus or grounded) to shield and protect the interference....
This is why i buy 4 channel scope and never make a video.... there will always be a some smart ass who can denny yout theory.... But mark my words, audio is something that trained ear can sense easily, and you can't explain it by electronic behavior
Let it be just any crossovers or speakers, cheapest or expensive ones, or even the whole audio deck system., The sound output must be clear and pleasant to hear, with good grounding bass guitar notes and tones frequencies, and the rhythm and lead solo or vocals must be crisp clear and the treble tweeters must emit good cymbals sound, especially of the hihat loudest cymbals sound. Thats ok to give you a real proper dose of every day required """DOPAMINE""'.
Thanks Larry - yes they do have a line of these crossovers. This one handles a fair amount of power, but if you do need more power than air cores will be great for that.
LOL are you now become a mind reader? :-) I was wondering about the placements of the conductors and under 4 seconds later you told about it:-) You talk about that things change with higher powers, is that due to heat, larger magnetic fields or? Looks like you have the same interests as me, but do of cause know oceans more then me! I do really look forward to follow you and your channel!! :-) EDIT: You made two videos about low and heigh pass filters, using a resistor and a capacitor, could you maybe tell about the difference and why?
Fried Mule Thanks Fried Mule - that is funny! Yes, with current loading the inductance will change a little, and parasitics can change as well. I’ll explain the difference in filters from the videos before - thanks for that idea! Anything else that you might be interested in a part 2, let me know.
Scope generator how many pick voltage amplitude voltage? My Second question this crossover test experiments DSO siglent model SDS814XHD in test posible answer give please 🎉
Thank you! You are right that the final test has to be with the chosen speaker. But, to compare crossovers, testing with a known impedance or resistance gives a reference point. Make sense?
What's your opinion on Dolby atmos mastered music Eddie? I know wealthy stereo sound purists who pay 50k for power cables immediately dismiss it but I believe atmos music sounds incredible and there's room for both types for poor plebian snobs who pay 5k for a whole system and some rich dude who pays for multiple 75 thousand usd record player cartridges for a 500k - 5m dollar system because it makes the high hats come to life in a 60 year old pressed vinyl myles Davis album.. hahahaha

I think that because mid-range is at 12db/oct both directions, it´s the reason why it says 24db/oct. :D
Thanks for your feedback! I'm going to do more crossover tests very soon;)
Many thanks for the vid, can you make a vid with them installed on speakers ? sound test ...
Thanks Ran! Yes I need to get some drivers and test them out. Glad to hear from you!
@@KissAnalog Thanks a lot, i love to see your professional way of explanation. hats off
Would this be a good replacement crossover for cerwin vega at 12
It probably would be. Does the cerwin vega have 3 speaker drivers?
You can measure all you want but on a HT receiver or low res system it does not have to sound much better .
If your system is capable of delivering high resolution and transparent sound you got to listen to the way each part influence the sound , with ear , yes with ears
Yes, the engineers that design and produce the low res and High res measure to be sure that they are hitting their perspective targets. It is up to us to check their measurements - and then finally listen to see if it is what we like - but measurements should always come first.
@@KissAnalog tonal qualities , harmonics , soundstaging and many other aspects must be heard and that is where quality of the parts plays huge role and it must be heard as perfect measurements can not show these qualities ....
I just picked up some old 70's B-I-C Venturi Formula 4 speakers and want to update the capacitors. Two of them are 16uf 50v and 4.7uf 50v. Do you think i will have a problem using 15uf 250v and 4.7 250V?
Using higher voltage is totally ok, and sometimes better even. Types of capacitors can make a bigger difference, like poly vs aluminum.
@@KissAnalog I got all poly! I let you know if it was a success
I'm in need of a crossover for a build those crossover frequencies are about where I'm wanting it, but I need something that will handle
2x12" 450w driver's in the bass section. Anyone know where I can get such a crossover?
Can somebody buy this crossover for a Pioneer CS G305 three-way 12-inch speaker and that sound good or would it have to be matched up with a certain kind of speaker
Yes, I think this might be a great option. When you open your Pioneer - it would be fantastic if you could share pix of the crossover inside it;)
@@KissAnalog I did take pictures there wasn't nothing inside their only close to the tweeters in the mid-range a little cap. off the connector in the back to the subwoofer there was nothing crazy
@@KissAnalog do you remember what the Hertz was on the low side for that model
Hello can connect my active speaker to cross over
Great question! Yes I think you could use this crossover to your active speaker. Are you thinking between the amp and speaker inside the cabinet?
hello,how to connect 3 speakers in Crossover IN out T and W ,my car have Under seat Sub BMW f30 and doors speakers with Tweet ,my amp out 4 ohm ,sub under seat 4ohm and doors 4ohm speakers build in Tweet , jumper wire around the capacitor to bypass it, serial or parallel connect and this Crossover filter 4 ohm??Thank u
Thanks for the question, but I'm not sure exactly what you need to know... Did you get this taken care of?
You need to connect 8 ohm loads to the speaker ports before you measure the crossover. I didn't see you add the loads and you will get a very different result.
Thanks for your feedback! I did several videos on this. Here’s one with a load. ruclips.net/video/kawTphp-sTk/видео.html
Hi why dont you make network for cube speaker like bose with light bulb in it
I once did a design where the lights changed with the music. Maybe I should try again;) Thank you!
Have you done much in active speakers?
If you like, I am a bit of an active crossover boffin...
Thank you! I an interested in this and do have some ideas and questions that I pose to you at some point. Anything you can share is much appreciated!
@@KissAnalog cool
hello, how are you, my friend? can you tell me how many meters of wire should i use for each frequency, and what thickness? thank you so much. like
Thanks for the question. I'm having a hard time keeping up so I'm responding to subscribers first;) This depends on what the core is, do you mean for an air core?
I liked your video enough to run with these 3 ways for a build of my own. But I am sorry that I had not finished watching before I placed my order. to use your link for you to get the amazon credit. But I did give you a thumbs up and subscribed to your channel.
Thank you Michael - that is great and I appreciate you! I'm really curious as to how you like them - please let us know.
Yes how did they sound and are you still using them?
That was pretty neat, thanks Eddie.
ATB Adam
Adam L Thanks Adam, let me know if there’s anything you would like to see in my part 2 of this video...
@@KissAnalog
Hi Eddie,
I'm just going with the flow of your videos, it will be interesting to see it loaded as Bert mentioned.
I believe that it may have something to do with reflections ?
ATB Adam
Adam L It very well might. It makes sense, so it will be fun and interesting to explore. I’ll post this weekend;)
@@KissAnalog
Great stuff Eddie
Can one combine the mid and bass output of a crossover to one so that it acts as a 2 way crossover ?
You could simply use 2 of the 3 outputs like maybe the tweeter and mid. But, we could see how you could use the parts of a 3 way to make a 2 way. I'll do another video to talk about this. Thanks for the feedback!
@@KissAnalog Thanks for the feedback. Waiting for the video.
Hi ,Just received the same but for 2 way divider model AS-23C , they have good quality parts , at least i believe hhh will see how they perform ! i am planing to replaced the cheap crossover i have in my bookshelf speakers with them. Thank you
That’s great! Let us know how it works out for you:). Thanks!
"BP" on a capacitor means Bi-Polar.
Mr kiss thanks
dipak bhalodia You bet! Let me know if there’s something that you would like to see.
@@KissAnalog yas crossover is use DJ SPEAKER SOUND
@@KissAnalog high pass filter or low pass filter correct?
dipak bhalodia Yes this has a high pass for tweeter, a low pass for bass, and band pass for the midrange.
Sir nice description thanks for effort this video
Thank you so much! I’m glad to hear from you!
Hello Kiss Analog . I wrote this question to you with the help of Google translate. I have a Dali Oberon 5 tower speaker. 2-way and 3-driver. It has 1 tweeter and 2 basses. at 6 ohms. Can I do this 3 way with Kasun 33C?
The speaker bass port is at the back and close to the wall. I'm getting too much bass. I want to use one of the bass drivers as a midrange.
To fix it you would have to wire one speaker out of phase to the other two.
Thanks John - that sounds like an easy fix!
Will this work on some Peavey 215 speaker
I have a 2 way version that I did several videos on. Check this out: ruclips.net/video/tq66AdM5oqA/видео.html
how to connect to if the woofer have 3 terminals
Eddy I am also interested of filters adding any Distorsion And which parts are responsible iff so
I am in a Dutch audio community And there are realy nice people I am building for fun tube amps ( i like the sound )
and I get a lot of help ! But tube amps have very heavy mains transformer
Nobody in this community ( dare or play save ) trying a SMPS
That’s wat I wanted to try out rebuilding a old ATX computer power supply in the near future
Like to know if you can , or willing to setup up a PP tube amp with a smps
And measure if there is a different in audio distorsie with a lineair power supply or SMPS
Let shake up this pre judgment a little 😀
Bert van Lelieveld Hi Bert, the distortion issue I think is a real thing. I’m sure the members of your Audio community would agree, and are really concerned. I’ll try to talk about that in the follow up video on this. I’m sure that this will be something that will develop over time and hopefully I can help work out these issues. This will be fun! I am a purest to a point, but I also think there are preconceived biases to the types of power supplies;) Let’s look into this and see what we find. These are the questions that I have had as well!
Thanks for the review in terms a person like me almost understands, I hoping to build my own 3way speakers using these crossovers, great coincidence as this was a random off ebay. Cheers from Australia
Thanks Steve - it is great to hear from our friends in Australia! I know you have a great RUclips channel with Dave there - so welcome;)
HOW MUCH BETTER WOULD THIS BODE PLOT WORK WITH A SPECTRUM ANALIZER?THERE ALSO UNEXPLAINED BLIPS THE PLOT.
I don't think a spectrum offers anything better in regards to Bode Plots. A spectrum requires a tracking generator to do Bode plots too. That's where these new scopes that can do Bode plots are so awesome. Thanks - that was a great question!
Lets restart, after watching your second video, i realize that you are on a right track, im sorry for going harsh on you... i would like to see more tests with actual speakers, and maybe comparing it with another different set of speakers, just to show people how big difference it can be.
Sorry you didn’t like it. Can you tell me what is incorrect? As an electrical engineer with decades of experience and who was the head of an electronics program for 3 years at a community college, I’d like to continue learning. So, if you don’t mind, what did I have wrong?
@@KissAnalog yep, this is the common problem with engineers....no offense... But audio is more than math...
You measure crossover without dedicated speakers... Attach them and you will see a big difference in your measurements, also you should measure interference between those parts... Also you need to measure phase difference after that cutting, because after the frequency goes down, also the phase moves away and you get low volume but still active out of phase sound from that speaker, 12 db is nothing special, its steap cutoff but there are a ton of music within that first 12db cutoff that is, at some degree out of phase, and you can hear that, and you gonna have a bad unrealistic stereo image...
Also as a engineer, you should know that capacitors and coils have their + and - , when outer level of coil is connected to the Amp - that means its grounded, and layers below are shealded from interference (positive end)... No matter if its a electrolytic cap or ceramic... Or whatever...they all have inner and outer layer.... Outerlayer is always (minus or grounded) to shield and protect the interference....
So if you have bipolar cap, still it has outer and inner layer
This is why i buy 4 channel scope and never make a video.... there will always be a some smart ass who can denny yout theory.... But mark my words, audio is something that trained ear can sense easily, and you can't explain it by electronic behavior
Thanks for sharing! Very interesting video topic.
You Bet! And thanks for the feedback - much appreciated!
Awesome scope
Thanks Jim!
Let it be just any crossovers or speakers, cheapest or expensive ones, or even the whole audio deck system., The sound output must be clear and pleasant to hear, with good grounding bass guitar notes and tones frequencies, and the rhythm and lead solo or vocals must be crisp clear and the treble tweeters must emit good cymbals sound, especially of the hihat loudest cymbals sound.
Thats ok to give you a real proper dose of every day required """DOPAMINE""'.
They have better models, the ferrite saturates and rings ,use air core models for better sound and higher power.
Thanks Larry - yes they do have a line of these crossovers. This one handles a fair amount of power, but if you do need more power than air cores will be great for that.
LOL are you now become a mind reader? :-) I was wondering about the placements of the conductors and under 4 seconds later you told about it:-) You talk about that things change with higher powers, is that due to heat, larger magnetic fields or?
Looks like you have the same interests as me, but do of cause know oceans more then me! I do really look forward to follow you and your channel!! :-)
EDIT: You made two videos about low and heigh pass filters, using a resistor and a capacitor, could you maybe tell about the difference and why?
Fried Mule Thanks Fried Mule - that is funny! Yes, with current loading the inductance will change a little, and parasitics can change as well. I’ll explain the difference in filters from the videos before - thanks for that idea! Anything else that you might be interested in a part 2, let me know.
MKP are high quality caps made in China.
Thank you!
great stuff
Thank you!
Scope generator how many pick voltage amplitude voltage?
My Second question this crossover test experiments DSO siglent model SDS814XHD in test posible answer give please 🎉
Would like to see the same test but with an actual speaker for each to see how much it would change. Love watching.
thedoc298 Thank you - I appreciate you! I’m very interested in that too, so I’ll get to that soon!
I'm pretty sure you can't test a crossover without a speaker connected as the impedance of the speaker will be a part of the filter.
Thank you! You are right that the final test has to be with the chosen speaker. But, to compare crossovers, testing with a known impedance or resistance gives a reference point. Make sense?
The base is 3d printed.
Ps: I'd also leave my wife, cats, house, massive garage and huge piece of property behind to elope with that scope hahahha
LOL - thanks Joey;)
BP for bi polar
Thanks so much for the feedback!
What's your opinion on Dolby atmos mastered music Eddie? I know wealthy stereo sound purists who pay 50k for power cables immediately dismiss it but I believe atmos music sounds incredible and there's room for both types for poor plebian snobs who pay 5k for a whole system and some rich dude who pays for multiple 75 thousand usd record player cartridges for a 500k - 5m dollar system because it makes the high hats come to life in a 60 year old pressed vinyl myles Davis album.. hahahaha
That's a great question Joey! I have a friend who swears by HD streamed music. I could see why it would or could sound better. As far as the Audiophile equipment goes - it really is a thing where the sky is the limit. I guess if you have the bucks - then have fun;) I hope to show the engineering side of it (or some of it) in videos to come;)
@@KissAnalog the Dolby Atmos stuff comes on bluray. It sounds incredible. I'm cool with the technical side. I was just off topic wondering Eddie haha. Thanks brother.
You can't check any passive filter without the load that it was designed for. That's kind of meaningless.
BP = Bipolar Polarisation
Thank you!
Ever seen toroidal inductors in a crossover?
Look it's James Hetfield!!
LOL - thanks!
Познавательно, но душно копец)
Thanks but sorry you didn't like it.
@@KissAnalog I mean, you spent quite a lot of time and commitment, your video is full of information, but that is the only review of this product, and i did not get, do you advice to buy it, on a scale 1-10 how nice it serves it's purpose ?
Oh OK;) I do think it is made of quality parts and seems to be designed and made well. I'd recommend it as I think it is a great value for the money. I'd give it a 8-9/10 just because it doesn't have the best capacitors. Not bad, but there are better.
@@KissAnalog thanks!)
you bet!
Cheap parts=poor sound quality.
These don't look like cheap parts to me. What parts do you like?
Crossover that's made with no particular speaker measurements makes no sense.
Terrible
Thanks for your feedback but can you tell me what part that you don’t like?
The coils are crosstalking , the slopes look terrible, build quality is pretty nice though......just the design is low end@@KissAnalog
Thanks! The coils are all 90 degrees from each other so how do you know that they are cross talking?
