There are many problems with this "guide". 1: It seems to be "logical" to install additional magnet in the same direction as the original, but in the actual arrangement flux is guided by the iron plates and pole piece, and they reverses the magnetic polarity at the place of usage (i.e. in the air gap) if the additional magnet is outside of the magnetic loop. Therefore the proposed direction makes the speaker weaker, not louder. 2: The additional magnet is in an open magnetic circuit with very high magnetic resistance, this because its flux is decreased significantly, and only a fraction of it arrives to the front plate. Furthermore, front plate is already saturated at the air-gap, this because increasing its flux significantly requires extreme magnetic excitation (which is not available here). The effect of a correctly aligned additional magnet to sensitivity is quite weak, however not zero. 3: As others mentioned before, the purpose of the additional magnet is not increasing sensitivity (it could have been done much more effectively inside of the magnetic loop), but far-field magnetic cancellation. Small enhancement in sensitivity is just a side-effect. 4: Nothing is proven. No measurement of TS parameters before and after. etc...
@@wackenroader Yes, I have many different speakers (including Sony bass speakers) with this kind of additional magnets, with or without shielding iron. My comment was about their *direction* and about its purpose.
@@PafiTheOne Yeah I mean I don't understand having repulsing magnets. I don't understand what you mean by magnet circuits or whatever. I'm like. if you want a stronger magnet on the speaker put it the same direction. Put them different dirrections??? just going tomake the magnetic fields less predictable?? I don't know I guess I haven't AB tested the magnets for direction like stated. Just seems like you would want all the magnets facing the same direction.
How calculate right magnet strong to 600rms 12 inch subwoofer? I have magnet 75mm 500kg power and subwoofer magnet is 180mm. Is that good use this 500kg neodymium magnet to this subwoofer?
When a coil is run through a strong magnetic field, after energizing the coil will vibrate in that magnetic field ... so the larger the magnet block, the more chance your speaker has of running at low frequencies. ... and more bass ... on the contrary, the high frequency will be slightly attenuated
the proper double magnet woofers/speakers will have the voice coil travel all the way into their pole piece ... which is the double magnet full distance travel .. but this ... you only just physically add another magnet on the back of the speaker magnet and it wont just work this way round ...
It's not genius work at all. A miltiple stacked magnet woofer takes into account the magnetic gap, voice coil former, and voice coil itself. There is a reason why a triple stcaked magnet is all together, and not stopped by the back plate, or the pole. It's asanine honestly.
They don't understand this... not to mention the fact that you can't produce that much Bass from a cheap 8 inch woofer. You need a real SUBwoofer to produce SUB sonic frequencies.
Of course the engineers designed the original of the brand speakers as well and right. But the manufacturers of counterfeit goods are many: this imitation is a counterproductive result. If a poor quality magnet is used for the speaker, then the imitation of the original's design will give a worse result. Cheap speakers will have super bad quality. Here I want to upgrade the speakers cheap
@mrdocprofessor patrick Not sure what you mean by noise, because the last time I checked, the whole point of a speaker is to make noise. Being as though you're using in a negative way I'm thinking you're talking about port noise. Being as though a speaker will move its least at its fB, you don't need any more control. As long as you build your box properly, you won't have any port noise at your boxes fB. So, either way you look at it, you're wrong. Not to mention the physics behind a loudspeaker has little impact when adding a magnet to it. The very, very, very, negligible increase of magnetic power to the speakers will be virtually inaudible. If it made such a big difference, don't you think car audio Enthusiast and home audio sound systems would always come with them? Isn't it funny how the only speakers at have them are the ones that would sit next to a TV or computer. It seems to be, maybe the reason for anti magnetization is less interference between electronic devices... Hmm. May I digress. Notice how the only people that religiously put a magnet on the other side of the motor are people that know little to nothing about the physics of loud speakers. Or, anything about acoustical engineering for that matter.
Ypu should know that the second magnet is placed opposing the first magnet in order to make the speaker less magnetic. It provides shielding, although to a lesser degree. It contributes nothing to the polarization caused by the main magnet, not it destroys it.
Alfred, your problem here is that the extra magnet does absolutely nothing at all to increase bass. You voice coil and voice coil former are only going to go as far down as the cone and spider will let it. Also, the voice could and former are going to stop on the back plate. Adding an extra magnet does nothing but add weight. It does not strengthen or increase the magnetic gap.
I have a old pair of Sony car speakers, over 10 years old at least, that has a coil winding around the OUTSIDE of the woofer magnet. I am clueless wth that is. Anyone know about that? BTW they have stonger deeper bass than 6 modern ones I've tried (2 jbl, 1 alpline, 2 kenwood, 1 pioneer. The model of the sony 6.5 inch is XS-HD160g. maybe a hair thin in mids but really good deep base. Better overall than any of those others. Can't find picture of magnet online, but has a clearly visible wide band of coated red coil wire around the OUTSIDE of the magnet and it's obviously is part of the mechanism. This is very interesting to me as I've never heard of it or seen it elsewhere I don't even know how it works or what that coil does. Any ideas anyone?
@@AlfredH it is wrapped around the OUTSIDE edge, yes the outside of the magnet. It is 9/16 inch wide, about as thick as it looks like the magnet may be, but the magnet itself is not visble, there is some cup or housing. The housing forms a 9/16 slot that appears to retain the coil. The coil is exposed, bare (but of course coated wire), huge and obvious. I giant red ring of wire around the outside of the magnet. I assume there is a normal voice coil, maybe this is an 'opposing coil' idk. have no clue what is going on, but it's obviously not just for show, lol. I have a picture but idk good easy way to share.
@@AlfredH ok I found the answer, and it's pretty impressive but idk how much it may matter in performance. Found some old promotional stuff online somewhere it says this (along with some unrelated info I left off): "The crossover's lowpass coil is actually wound around the woofer magnet, to achieve maximum performance in minimum space". Meanwhile I've found the sound of these speakers to be sorta unique and now I want to repair what I think is a bad woofer voice coil but idk if that is possible. I'd have to know how to take it apart but ever harder I'd have to be able to buy a replacement coil. Of I would rather just buy the same speaker again. I just bought and tried 7, yes, 7 different speakers, and don't like them as well after playing them again the other working sony in the other door. I will prolly get maybe 2 more higher priced pairs to try but after that I guess I will just have to go with whatever is best among them. So far the JBL 6522ix is the best among it's class vs alpine, polk, kenwood, and pioneer, but it has a low mid bump that is annoying, and still not as deep and controlled in bass as the sony, while better than the others. So I may get some of the pricey sony's, I didn't try really low priced sony's. I couldn't find these 'mid priced' in sony. I've been testing freq sweeps on them in a large insulated box, and also testing free air resonance. Those test are actually consistent with my listening preferences. I haven't mearsured the old working sony yet, have left it in the door, but I will test it when I finally replace it or sooner.
Why don't you measure TSPs? Then you can see with which orientation of the added magnet the strength of the magnetic field inside the gap (called BL, BxL or B*L) increases more.
There are a lot of clips about speakers. I was the first to do this project. I always analyze the technique ... if you believe me ... If your speaker magnet is bad quality. Please let it stick to each other If your magnet is of good quality, leave it in the opposite direction (pushing each other)

How calculate right magnet strong to 600rms 12 inch subwoofer? I have magnet 75mm 500kg power and subwoofer magnet is 180mm. Is that good use this 500kg neodymium magnet to this subwoofer?
When a coil is run through a strong magnetic field, after energizing the coil will vibrate in that magnetic field ... so the larger the magnet block, the more chance your speaker has of running at low frequencies. ... and more bass ... on the contrary, the high frequency will be slightly attenuated
This is a bucking magnet configuration. This lowers the electrical Q and increases sensitivity but not by as as you may think.

I also love the opposing magnetic force sound effect. It pumps me up!!!
Sound effect?
Yess thanks bro i tested it and my speaker became louder and more bass
jadi yang bagus itu saling tolak menolak atau tarik menarik? untuk subwoofer, woofer, midle, tweeter.

the proper double magnet woofers/speakers will have the voice coil travel all the way into their pole piece ... which is the double magnet full distance travel .. but this ... you only just physically add another magnet on the back of the speaker magnet and it wont just work this way round ...
Exactly. You will however add some form of shielding so you can place the driver closer to a CRT Display, Cassette, floppy disks, etc.

hi sir this magnet north and south pols but i can tray this battery and coil test no it working tell i am how do it
I do not understand
hi sir i mean how make electromagnetic i am lots more try it not working
You do not need to test
You attach it and listen for a while
i tried that already but still no effect for the sound..fake video
this video is no fake
Hello everybody. I will upload the subtitles right away

jadi kesimpulannya apa Bang Alfred ??? yang bagus menambahkan magnit berlawanan atau tarik menarik ?? soalnya kurang paham penjelasannya 😁
Explain how it gonna work
The video has subtitles that you
Look like the second magnet function is for damping the voice coil. This will increase power handling of the speaker.
Your opinion is very correct. There will be few people as knowledgeable as you. you really know!
Thank you very much
Bro so the second magnet needs to attract or deviate?
@@rajkhumar001 the second magnetic use to block the voice coil so it does not hit the back.
@@andrewng5211 bro so your advice to not use?
@@rajkhumar001 block it. So the coil only can move forward. So it can handle more power. Else the core will burn.
Amazing 😍
Alfred, not all can digest a genius work.. keep it up, i am benefited the most. thanks
Thank you very much
It's not genius work at all. A miltiple stacked magnet woofer takes into account the magnetic gap, voice coil former, and voice coil itself. There is a reason why a triple stcaked magnet is all together, and not stopped by the back plate, or the pole. It's asanine honestly.

Hey bro! It was a great video. Helpful content. I was looking for this type of review
To increase the bass output just simply add a low pass filter or crossover in input audio system done
They don't understand this... not to mention the fact that you can't produce that much Bass from a cheap 8 inch woofer. You need a real SUBwoofer to produce SUB sonic frequencies.
It mean S polar meet S polar right?
Mantap smua nih vidionya
the manufacturers know how and what measures to take to keep it from blowing or distorting.
Of course the engineers designed the original of the brand speakers as well and right. But the manufacturers of counterfeit goods are many: this imitation is a counterproductive result.
If a poor quality magnet is used for the speaker, then the imitation of the original's design will give a worse result. Cheap speakers will have super bad quality. Here I want to upgrade the speakers cheap
where could we buy a speaker magnet?

Fail again. Adding a magnet doesn't do anything for the sound
@mrdocprofessor patrick Not sure what you mean by noise, because the last time I checked, the whole point of a speaker is to make noise. Being as though you're using in a negative way I'm thinking you're talking about port noise. Being as though a speaker will move its least at its fB, you don't need any more control. As long as you build your box properly, you won't have any port noise at your boxes fB. So, either way you look at it, you're wrong. Not to mention the physics behind a loudspeaker has little impact when adding a magnet to it. The very, very, very, negligible increase of magnetic power to the speakers will be virtually inaudible. If it made such a big difference, don't you think car audio Enthusiast and home audio sound systems would always come with them? Isn't it funny how the only speakers at have them are the ones that would sit next to a TV or computer. It seems to be, maybe the reason for anti magnetization is less interference between electronic devices... Hmm. May I digress. Notice how the only people that religiously put a magnet on the other side of the motor are people that know little to nothing about the physics of loud speakers. Or, anything about acoustical engineering for that matter.
Very good.
Thank you very much

Title is english,

so why aren´t you?
Ypu should know that the second magnet is placed opposing the first magnet in order to make the speaker less magnetic. It provides shielding, although to a lesser degree. It contributes nothing to the polarization caused by the main magnet, not it destroys it.
It has contributed to the bass increase
It's only magnetic shielding,it doesnt't change anything for the sound
Reason to stop the magnetism?
Oh okay
Alfred, your problem here is that the extra magnet does absolutely nothing at all to increase bass. You voice coil and voice coil former are only going to go as far down as the cone and spider will let it. Also, the voice could and former are going to stop on the back plate. Adding an extra magnet does nothing but add weight. It does not strengthen or increase the magnetic gap.

They do something... when you adding magnet, you need more power to make speaker work..
I have a old pair of Sony car speakers, over 10 years old at least, that has a coil winding around the OUTSIDE of the woofer magnet. I am clueless wth that is. Anyone know about that? BTW they have stonger deeper bass than 6 modern ones I've tried (2 jbl, 1 alpline, 2 kenwood, 1 pioneer. The model of the sony 6.5 inch is XS-HD160g. maybe a hair thin in mids but really good deep base. Better overall than any of those others. Can't find picture of magnet online, but has a clearly visible wide band of coated red coil wire around the OUTSIDE of the magnet and it's obviously is part of the mechanism. This is very interesting to me as I've never heard of it or seen it elsewhere I don't even know how it works or what that coil does. Any ideas anyone?
Where is that coil located?
@@AlfredH it is wrapped around the OUTSIDE edge, yes the outside of the magnet. It is 9/16 inch wide, about as thick as it looks like the magnet may be, but the magnet itself is not visble, there is some cup or housing. The housing forms a 9/16 slot that appears to retain the coil. The coil is exposed, bare (but of course coated wire), huge and obvious. I giant red ring of wire around the outside of the magnet. I assume there is a normal voice coil, maybe this is an 'opposing coil' idk. have no clue what is going on, but it's obviously not just for show, lol. I have a picture but idk good easy way to share.
try this. the one on the left. idk how long it will stay up there: ibb.co/Rzyfb94
sony xs-hd160g
@@AlfredH ok I found the answer, and it's pretty impressive but idk how much it may matter in performance. Found some old promotional stuff online somewhere it says this (along with some unrelated info I left off): "The crossover's lowpass
coil is actually wound around the woofer magnet, to achieve
maximum performance in minimum space". Meanwhile I've found the sound of these speakers to be sorta unique and now I want to repair what I think is a bad woofer voice coil but idk if that is possible. I'd have to know how to take it apart but ever harder I'd have to be able to buy a replacement coil. Of I would rather just buy the same speaker again. I just bought and tried 7, yes, 7 different speakers, and don't like them as well after playing them again the other working sony in the other door. I will prolly get maybe 2 more higher priced pairs to try but after that I guess I will just have to go with whatever is best among them. So far the JBL 6522ix is the best among it's class vs alpine, polk, kenwood, and pioneer, but it has a low mid bump that is annoying, and still not as deep and controlled in bass as the sony, while better than the others. So I may get some of the pricey sony's, I didn't try really low priced sony's. I couldn't find these 'mid priced' in sony. I've been testing freq sweeps on them in a large insulated box, and also testing free air resonance. Those test are actually consistent with my listening preferences. I haven't mearsured the old working sony yet, have left it in the door, but I will test it when I finally replace it or sooner.

DeathMarchKiller WTF did I just read lmao
Why don't you measure TSPs? Then you can see with which orientation of the added magnet the strength of the magnetic field inside the gap (called BL, BxL or B*L) increases more.
because magic!
Hey when you get a chance respond back. I got 2x 15 inch subwoofers an I want to make a big speaker

Your opinion is the treble / bass circuit?
Not just trabe bass.... i want subwoofer pcb which connect 1woofer speaker or 2mini speakers.
Your opinion is 2-way differential frequency

It’s so complicated to talk about simple things, I still don’t understand which direction is right.
There are a lot of clips about speakers. I was the first to do this project. I always analyze the technique ... if you believe me ...
If your speaker magnet is bad quality. Please let it stick to each other
If your magnet is of good quality, leave it in the opposite direction (pushing each other)
