You should do a sound comparison between the ferrite magnet and neodymium magnet.

[@homemade_audio]

personally I don't believe much in comparisons of sounds on youtube, including recording equipment, listening location, editing, equalization, youtube tuning and final listening equipment (most of the time the telephone speaker) the result is probably far from real. in the video I showed several techniques that are very important to remember to do a lot of things on speakers.

[@Sodabowski]

@@homemade_audio how does the modified speaker sound like? Clearer on the high frequencies? I was also expecting a comparison, even though compression will inevitably mess things up 😅 you're an amazing master of this stuff by the way, thanks heaps for putting up these videos!

[@homemade_audio]

thank you for your comment, first the modified driver is a midwoofer, already there are no high frequencies !! but what I noticed is that with the neodym magnets I have a softer sound with less presence of midranges, and a good presence of bass.

Todo esse trabalho é em vão sem analisar os parâmetros T&S e resposta de freq antes e depois.

[@axelbelleris]

On the back, where the magnets are, the coil was exposed and dirt, dust, etc. could get in, which over time, will cause it to have friction, sound bad, and even the coil to get stuck. I, instead, would cover that opening with clear plastic so that it can continue to be seen when it moves. Even, to make it look prettier, I would add some LED lights. Good your idea, only the sound check was missing. Greetings from Argentina. 🇦🇷

[@emmet7208]

This is not necessary, many high end drivers leave this area exposed, it is great for cooling the driver, and if the woofer is properly enclosed in a good box, there will be no problems.

To combat heat, neodymium drivers will often have an open motor structure. Neodymium is weakened by heat.

[@dougcox835]

Definitely doing things the hard way. I think you can just buy a speaker kit with all the parts and just put your magnets in there instead of the supplied one. Maybe I'm wrong about that though but a guy I knew years ago would do exactly that to repair speakers. But this video is an excellent demonstration of how a speaker is put together.

[@pinarellospeedracer]

So I installed a new sound system in my 2010 BMW Z4 and installed Focal separates front and rear ,It sounded ok but to me the titanium tweeters was way to bright . So I ordered some vibe speakers from the UK and they have neodymium magnets in the drivers and the tweeters are a silk soft dome. OMG they are so crisp and clean with no distortion at all. I listen to a lot of Jazz and now the vocals and drums are so awesome

[@Synthematix]

Yep the English make the best speakers

[@dominikspencer3981]

No, the Danish make the best! Scan Speak, Vifa, Dynaudio, Eton Electro, Peerless, Tympany, etc. Anyways, the neo magnets did not improve your sound. Most likely just a better match. Many of the Focal tweeters that come with the components are kinda sub par. I always went for their inverted dome Kevlar ones. Soft not harsh, hits the high details, non fatiguing. My favorite car front end drivers have been Focal since 1986. I used to use their home audio drivers decades before they made car audio gear...

The most important thing you didn't do, that was the reason for the video, was to demonstrate how the improvement worked. Why would we want to do this, we don't even know if this works, and if so, how well.

[@stevetalin6489]

Very cool and informative video. I may consider that for a much larger speaker as I’m not sure that one is worth the effort. Also you must seal the perimeter of the exposed magnets with tape or plastic to prevent debris from getting into the voice coil and pole assembly. Otherwise very nice work.

[@homemade_audio]

Yes i agree with you, glue isn't enough to hold well the magnets, but the best way t keep voice coil safely is to hold the two métal parts of magnets assembly with bolts. You welcome

[@stevetalin6489]

No no that’s not what I’m saying. If you look at the speaker from the side you can see the voice coil through the magnets. Debris can fall in between and get lodged in the voice coil.

[@nomoimusic3096]

@@homemade_audio I thought perhaps an epoxy encapsulation of the magnets could be made to have the exact same toroidal shape of the ferrite magnet and thus have a closed design just like the ferrite one but with neodymium, what you think?

[@simonspeaker]

you could use a kind of screen net sheet over it

[@lp9290]

The risk of debris is real but you also have to consider that exposing the coil to the air the temperature of the coil cools down during the activity and this may increase the power handling. The greater attraction of the magnet may also increase the excurions of the coils and there is the risk of a deformation of the botton of the coil hitting on the base plate because rhe greater length of the coil movements. The magnets have been glued but the are many vibrations so there is a risk that some magnet detach in the long term. To connect the top and base plates with metallic bolt may deform the magnetic field as well .

[@davidrendek2399]

@@homemade_audio Do you have an unmodified speaker model? Could you measure the deflection of the membrane at the same DC voltage with and without modification. You would immediately know whether the strength of the magnetic field in the air gap is greater or not. It is not demanding on the equipment. Of course, it won't tell you the T/S parameters. Purely theoretically, however, they should be preserved if the rest of the moving system was not adjusted, only the sensitivity of the speaker should be improved.

Great job! That's some insane craftsmanship and machinery you have. Would've been interesting to see how the efficiency of the speaker changes. Feeding both the ferrite one and the neodymium one 1W and measuring it's volume. Also I am wondering whether putting the magnets closer to the coil would've granted a higher efficiency.

[@BlindDude]

I dont think the magnets being closer would do anything. The core is what decides where the magnetic fields go.

[@barthchris1]

edit

[@djdod2926]

Nice mod and good craftmanship from you. similar to Anilco speaker 😀😀😀

[@Skarfar90]

AlNiCo* was kind of the neodymium of old. Neo motors, like the old AlNiCo are highly efficient, and can produce good volume at low power. I have tested neo drivers and directly compared them to similarly powered ferrite drivers, and the difference is very noticeable. Neodymium is more common in smaller drivers, especially in modern tweeters and mid-ranges. Pro audio drivers in particular often use neodymium motors, because of their high efficiency. Though, some high-end subwoofer drivers use neodymium motors as well, it is rather uncommon in large drivers, since neodymium is much more expensive than common ferrite. Large high-power coils will often produce high temperatures too, so that is why neodymium drivers often have an open structure design, since neodymium gets weakened by heat. * AlNiCo is an alloy made from aluminium, nickel and cobalt.

[@philfrydman2576]

Very interesting vid & I can see the skills to redo the driver. I have the following comments... Artificial magnets (Samarium Cobalt and now Neodymium) are used where space/weight is reduced and strong mangnetic fiels is needed (= maximum energy produc or magnetic density): headphones, in-ear headphones for audio and electric motors (EV), hard drives, RC servos, military/space apps,... I can't see an audiophile taking the risk of upgarding to neodymium while having a big risk of downgrading the balance of cone and precisely centered coil while standard drivers/speakers are already designed for the best performance. I will not take a chance to fiddle with my Harman Kardon and Bose speakers.

[@ToniPfau]

@Homemade Audio Great video. Thanks for posting. I've had very little luck getting speakers apart without destroying the frame. After watching this maybe I'll try again. There was a lost opportunity here. If you'd made the polepiece with an undercut you could have added a conductive sleeve (copper or aluminum) under the magnetic gap and another above and significantly reduced harmonic distortion just the way the expensive high-end driver manufacturers do. In addition I've thought of shielding the outside of the magnetic gap as well. I'd attach to the back of the top plate a 1/4" aluminum plate, that plate having a hole perfectly lined up with the hole for the magnetic gap. In addition there would be holes drilled through the aluminum that will locate the 8 magnets. Add another piece of aluminum to the front of the top plate, similarly aligned with the magnetic gap, and you get a near perfectly shielded magnetic gap. That should reduce harmonic distortion dramatically. Maybe when I have time, money, and the right state of mind I will try that. Thanks again for posting this.

[@johnruscigno5738]

This would be great for subwoofers. Better for lower frequency and the coil seems like it would stay cooler with the extra air flow. Curious about how it performed

[@СтоянЙорданов-о1ц]

You could have done some "before and after" measurements, such as the magnetic field strength in the voice coil gap, as well as measuring the frequency response at 2.83 volts and at 1 meter distance. You could also have wound a new voice coil on a Kapton base, for even better performance. Also, when centering the system, it is more correct to place the separator in advance, and slide the voice coil with the cone and spider down on it, and not the other way around. And don't be offended, I'm writing this for the purpose of constructive criticism. Greetings from Bulgaria :)

If it was better why havent subwoofer makers making them from factory? I think i have heard tweeters made with neo magnets. In my opinion must make the price jump and the sensitivity go down due to over coming a strength of the magnets? Just ideas. Nice work tho

[@adrianmarin3195]

One should cover up that magnets enclosure, as dustproof as possible....average urban dust contains small grains of sand, earth including metal particles of which some are magnetic also....they will accumulate and get trapped into the vibrating space of the membrane's coil therefore it will strongly affect the way electric impulses are turned into sounds so distortions will occur....also, due to friction of the coil with such trapped grains, short-circuits may occur and/or the wire gets cut......

[@Grommet2007]

Interesting modification. I wonder how much the driver's t/s parameters changed with the change of magnet? A stronger magnet will result in Qes and therefore Qts going down. Fs will probably go do slightly, not because of the magnet, but because of the additional glue, which adds a slight bit of mass to the cone. Room EQ Wizard (free software) and a simple impedance jig can be used to measure the parameters of the original driver and the upgraded one for comparison purposes.

[@homemade_audio]

TS parameters certainly changed, not only because the magnet have been more strong, also because the old ferrite magnet create a small closed space behind the cone assembly, now with neodym magnet the cone becomes free to air on back, the result: the midrange becomes clear and soft , and the bass becomes strong, because i feel more bass power on my hands when i tested the driver.

[@Grommet2007]

@@homemade_audio The increased bass power could also be caused by a reduction in BL, which will lead to more output around the driver's resonance frequency. The best way to determine what impact the change has had on the driver is to run an impedance sweep on the unchanged one and compare it to an impedance sweep of the changed one. If the impedance peak for the changed driver is lower and narrower, then BL has gone down.

I think it's better for the neodymium magnet to keep the original magnet thickness so that the voice coil position is at the right position. Furthermore, the voice coil should not expose to outside which will collect debris into the magnetic gap.

Would have been interesting to use a piece of the green magnetic field viewing film to put over and see what the field lines look like before putting the cap pole piece back on!!! Additionally Would have been interesting to drill a vent hole through the pole piece for ventilation and cooling the voice coil as the dustcap looked like it was not permeable to ventilation. No ventilation between the dustcap and pole piece means you have an enclosed cavity that seems like it might hinder the Xmax excursion and truncate the SPL capability.

If you just want a stronger field, and there is a nice big core like that, and there is room in the enclosure - all you have to do is add magnets to the back or sides. That will strengthen the field. With surface prep, cyanoacrylate (super glue) would be fine. Just need to think a little about the field. You can get donut or wide disk neodymium magnets too. Or just double up with another copy of the existing ferrite magnet. Flux linkage is a thing. But with a stronger field, you could exceed excursion limits. While you were machining, you could have cut recesses for the magnets for friction fit.

"Pro": Only in this case, the voice coil works cooler because it is much more exposed to the weather outside. "Cons": The final sound is totally changed due to a drier, more annoying sound, since ceramic magnets are preferred par excellence for their magnetic damping capacity to sudden and repetitive changes in the magnetic polarity of the voice coil. To solve this defect with Neodymium magnets, another diameter of voice coil must be used that resonates with the woofer casing, using a more robust casing to avoid harmonic fluctuations produced by the bending of a weaker casing which is not structurally prepared to withstand large magnitude torsion. You should also consider changing the cone material to a much stiffer and thinner one or use another type of cone material that is much softer than the original and thicker. Changing the permanent ceramic magnet for a neodymium one in a speaker with these characteristics, just like that, only worsens the final sound and good results are not obtained if its structural manufacturing characteristics are not considered.
