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.

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. 🇦🇷

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

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......

If your video was narrated, you would get so many more views and subscriptions. You can even use an AI to narrate so you don't have to find or pay anyone. It would improve your videos and possibly answer some lingering questions people might have. 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.

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.

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 .

И что? Результат то какой? Что изменилось? Если ничего не переделывать он тоже играет!!! Смысл переделки?

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.

Nice man!👍🏻

👍👍👌👌

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.

You have not tested the sound of both speaker differences and what good sound will it bring? We want to hear the sound difference of both the original and the modified one. How is that?

what benefits does this have? Am I wrong in thinking that the voicecoil should be changed as well, in order to allow more travel. I dont really no what Im talking about but are neodymium magnets primarily used to make a smaller speaker more efficient than had it used a ferrite magnet?

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

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.

does neodymium Magnet make speaker sound better or it is just a cliche?

Because of this project you've got a new subscriber here sir. May I add some suggestions if you may on the magnets installed. How about you drilled a 2mm deep pocket for each neodym to seat on aside from gluing it down and also drilling four bolt holes around the base for a bolts and nuts to go through from basket all the way to the back as clamping so if ever the glue gets dull none of the individual parts would move around and gets misaligned. I would love to see a bigger version of this project (a 12" or 15" maybe😄). Great contents sir 👍

Did it got more sensitivity? By how much?

Better to have all of the coil within the magnetic field for the sake of efficiency.

What material did you use to center the magnetic assembly?

Test the sound and see which is beter before and after upgrade.

Que uso para ablandar el pegamento del cono ? Water ?

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.

What do you use? Acetone or ipa isopropyl alcohol

How did you do to center the new magnetic assembly?

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.

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.
