@@Dakoustics... Another thing for audio experts are the acoustics designs of speaker peripheral boxes. Some guys can't stand modern day speakers because they notice the sound acoustics differences in today's designs vs 1970-80s designs where speaker acoustic (the total wooden box and speaker system) sounded for stereos back then. Case in point: Why have modern TVs with HD require soundbars when TVs had great acoustical sound back in the 1970-80s? Back then listening to stereos and their designed speaker systems those amplifiers blew such rich sounds the ear couldn't differentiate a live vs record playing (or of FM radio station) performance. I still have the latest greatest RTR-IV 1982 from 50 Watts lower grade speakers outperforming many speaker designs today by an engineered speaker wooden shell also.

@recon4402 жыл бұрын
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.

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.
@Dakoustics2 жыл бұрын
Ah, an unfortunate problem far too many face. In order to turn your Yousless pig-iron into neodymium magnet, follow these simple steps: 1. A good nights sleep and hearty breakfast is a good way to start this day. 2. Place the pig-iron into the ceramic induction furnace, as prepared in step -3. Heat to a nice red glow. Barnaby Joyce face for reference. 3. Scrape off the SCUM. This might be carbon. Dispose of responsibly. You now might have pure iron idk 4. Assuming you ordered $75000 of Neodymium magnet, and the price is competitive, That's roughly 159.57446808 kg of neo magnet, aka your precious pig-iron. You must now add 58.92999028869 kg of elemental neodymium, which is found in the earth. A warning- it is also rare. 5. Add 38 cloves of Boron (which happens to be the 2.2kg required). 6. Make sure the broth is proper sunburnt Barnaby Joyce who's under ICAC investigation hot. Stir thoroughly. 7. Pour over your existing feeble speakers. If they are weak, they will ignite, and good riddance. 8. Wait for it to lightning. Your magnets are now magnets.

@@Dakoustics Thank you Mr. Dak. I have now been able to turn my pig iron into the neodymium magnets I so sorely needed. While the process caused my house to burn down and has turned me into a fugitive because it killed my neighbors in the induced lightning strike, I can now escape in style with my new speaker system. A shame I don't have any music to play, but I have connected up the speakers to the engine, and it is indeed very loud. Thanks again Mr. Dak

For me Xmax mostly depends on max THD. When you take a neo magnet and Ho frame with 3mm pole, you'll get a 1.5mm Xmax. Period. Otherwise this would be a tr.. driver. So, this layout is good for a highly efficient compression driver only. PS ...and for a car "audio" of course. Then you can mound this driver on a suspension and get 2 in 1: a dancing car and a loud "boooo"

I heard that You can’t just replace a ferrite magnet with neodymium. It’s needs to be re-engineered and the neodymium requires more steel to generate a more powerful motor vs ferrite. More steel, more weight. So it’s not AS light as an optimistic example Also ferrite is easy and cheap to magnetize. Neodymium is complicated and expensive
@iridios612710 ай бұрын
*@johnviera3884* These rumors are not true. The only difficulty is - not to pinch your fingers or break the magnets themselves during installation. Need to use spacers and shims.
