Thank you so much for your great comment, really I'm audiophile and a big fan of speakers from childhood, especially vintage jbl monitor studio. In my life I'm technician (electromechanical) but audio diy is my favorite things that i do with love. You welcome 🥰🙏🙏🙏

Glad to know that. Keep up the good works.

Pai...Probe nu?

I am from assam

​@@homemade_audio❤

I was wondering that

It can, but if the speaker has a trash coil then it wont affect much

Probably not, but it has a lot more power. Perhaps more punch to the sound?

😂

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

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.

@@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!

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.

What liquid is, that you injected?

It's mentioned on the video (Paint thinner)

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.

why does everything need LEDs these days????

🫣 use incandesent for pretty. leds are never pretty.

​@@dhmusic2031 it doesnt. leds need ripping out of everything 😂. ive got a whole room in my place set up with only incandescents so i can get some relax light for my head. and every one diffused through some natural media. im so done with flickering.

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

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

edit

Yes i agree with you, very logical question, but I don't have materials to get the new T/S parameters. I'm planning to buy Dayton Dats software in the future.

@@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.

@@davidrendek2399 More Qes, less bass, more sensitivity. More Qts. More is lower number. deflections can be higher at resonance with less magnet. The right amount of magnet is best.

TS fundamental parameters are all the same except Bl is now infinite 🙂

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

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.

@@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?

you could use a kind of screen net sheet over it

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 .

Open magnet system can attract ferromagnetic dust

agreed lol

Yep the English make the best speakers

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...

Here in the uk Vibe is a budget brand for the kids. Vibe may be designed in the uk but its made in china

@@Synthematix Unfortunately the majority of British speaker brands are now designed in the uk but made in china

Titanium & Aluminum domes can have a certain "ring" resonance to them if not designed properly!!! Silk cloth domes always have the best response & imaging IMHO!!!

Hello, the last sentence on your comment is the target 😉

just buy a 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.

Thank you 🙏

Thank you 👍👍👍

Thank you 🥰

Thank you for your comment🙏🙏🙏 you welcome 😉😉😉

All glues are mentioned on video

Thank you my friend, it's really nice to get nice words after sharing a video that takes me a lot of time. Thank you 🙏

if you have watched the video carefully, you will notice that if you replace the ferrite with a neodymium of the same height, you will not need a machining machine in your kitchen drawer 😁😁😁

everything is mentioned on video

Thank you 🙏

UHU rubber glue

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.

@@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.

​@@homemade_audio It moves more easily, but dust also enters more easily and can damage the speaker winding

​@@homemade_audioyeah I love it.. upload sound comparison in wav format

Просто для контента. Разумеется, делать такое всерьёз это полный бред.

He used paint thinner

Yes. It's not easy to get a good basse fréquences response from first test, this fabric elastic suspensions sounds good from first day, the sound is recorded based on zoom h2n.

@@homemade_audio and I didn't see any sound samples in this video that is all. thanks.

Yes i agree, this video is to show you how to make a speaker driver rather than changing magnet.

You have also lost a huge heat sink with the old magnet. Worthless modification

@@castuart81 think about the heat source and it surrounding before and after the mod.. you have here direct convection with more air. don't forget, anilco speaker were built that way. this mod is an overall improvement over the ferrite one...

🤣🤣🤣👍👍🤣
