Neodymium VS Ferrite Magnets in Speakers!

With more choice than ever, it's difficult to know if a neodymium speaker really is worth the asking price. In this video I go through the differences between standard Ferrite magnets and Neodymium magnets, and show the difference the magnet has on the performance of a speaker.

Your videos is always above and beyond on explaining that really shows your own understanding of the dynamics is really complete. Its better than a technical college class, thank you so much!

[EngineeringEssentials]

Awesome, Packed with a ton of information, watched 3 times to fully understand. Thank you 🙏

[HiFiNi-TheDigitalScientist]

One of if not the most interesting video I've ever watched in my life 🤓

[brucermarino]

An excellent demonstration. Another benefit of neodymium in some applications is that their smaller size can lead to fewer reflections through the cone. Thanks again for such great work!

[jmpsmash]

Brilliant. Really like how you went through the equations and math. It is hard to gain the same understanding from just reading a book.

The neodymium magnets helped me a lot when I made panels so that everything could work properly like the passenger locker. Their shallow depth solves many problems. Thank you for this video master !!!

Very informative video. I've read a lot of a B&C whitepapers and they recommend to get as much BL as possible regardless of any case. The one item worth exploring... apart from raw SPL is the apparent power required to generate said SPL: SPL vs. VA vs. frequency in WinISD, or Hornresp (which I prefer). Hornresp also gives an "Efficiency" plot in this regard derived from SPL vs. power. In the car audio game, a lot of the high-BL woofers will not model well on paper in a small box but when normalized watt for watt compared to low-BL offerings, they are far more capable, with the tradeoff that you need a similarly capably voltage source.

Learned a lot unexpectedly. You're video is really great and informative. Thanks for sharing

[russsmith]

All I can say is well put man Damn, you really know your stuff. Thank you. I learned a lot from this video.👍

[jahn-pierrezietsman]

Thank you so much for all your videos. They are so informative. Thank you for taking the time to make them. I really appreciate it...

¿which is better, one large intonation port or two small intonation ports?

[johnnycorn]

This is why I'm thinking 6 12-in subs with smaller ferrite magnets would be better than 218 in neos better heat dispersion and more surface area in 12 cubes

Great info mate. Thanks for sharing. -Cheers

Excuse me Mr. Dak, I bought some Neodymium magnets off of Wish, and when they arrived they turned out to be Pig Iron. Would this still be an effective magnet for use in my speaker system? They cost me $75000 and I really don't want to return them. Please help me.

Hello im buying two dual 15" pa speakers with ferrite magnets can i expect great quality audio with these or will if differ compared to the other type of magnet and if i was to reload active speakers how would i go about it could you talk to me on email once i have them thank you im wondering what someones thoughts are on this they are vonyx speakers not sure if anyone has used them and what they think please talk im serious about audio quality i used to own a pair of mackie thump 15a's and they were great but im worried i may be going the wrong way they look very nice they are rated at 35hz for the low end and upto 20khz for the top end of the frequency response

[davebutler]

interesting! thanks for sharing your reseach.
The atari music is an annoying disdtraction though!

[truthbtold]

Brilliant the information is 100% correct. Thank You!

[Elnufo]

Good informative Video, thanks for sharing.

Tip: Magnets are hotter when you increasing the volume of bass. Once you get a distortion of subbass it's hot in a few minutes of listening some music.

Strength per dollar is an interesting unit of measurement
