Best full range hifi homemade driver needs research and development

[monoiz15]

I've built a different version of this and the sound quality and frequency response are incredible! It's based on some very powerful new discoveries, but I'll leave it to you to do the research on the RODIN COIL and VORTEX BASED MATHEMATICS.

People need to play around with these and find out how to properly integrate them into actual loudspeakers. Not sure how you would build an enclosure for these or if they even need one.

Does that require a crossover that uses a flux capacitor?

No, just a 1.21 jiggawatt amplifier.

Re: Best full range hifi homemade driver needs research and development

That reminds of my headphones from many years ago. I took the pin out of a bicycle crank and wrapped lots of wire around it. Hooked the wire up to an amplifier and then carefully crammed the metal pin into my ear canal. Wow--pretty decent sound (really). And just as non-amazing as this contraption.

The sound was good, but after a while the heat started to get uncomfortable. Probably a good way to melt away earwax, but I never left it in long enough to find out.

Re: Best full range hifi homemade driver needs research and development

That other thread was mine from a while ago.
It doesnt require a crossover, it has a verry good response, it just doesn't project sound very much as a coil alone.
The one I made does require a good amount of power to really make some sound.
And it will heat up after a while of playing.
This is why I said it needs R&D. I believe it has incredible potential but is currently in its most primitive form. I'm building another one once I get the schematics for this version.
Definitely worth researching imo.

The rodin coil strikes again!

I watched 1 or 2 of the Rodib youtube videos once, got to admit I'd take the guy a lot more seriously if he wore pants...and a proper shirt.

You're talking to engineers here. If you want their attention, you'll need to substantiate the phrase "Very good response" with some sort of measurement.

Also, the fact that these things get hot quickly is not a good thing. Loudspeaker drivers are already incredibly inefficient. If this Rodin coil is less efficient, then I don't see how it's going to attract any attention.

He lost me at using the "Luminiferous Aether" to explain it. :(

Re: Best full range hifi homemade driver needs research and development

I've pressed some tactile transducers on my ears before and they sounded quite pleasant. The problem is getting them in the right position to achieve the nicest response, a lot harder than normal headphones. They also require more power than normal headphones, but there is a more "natural" sound to them without the harshness and fatigue of a lot of <$100 headphones. Probably not as private listening given that your ear is playing the music!

This coil is based on what I believe to be the numerical solution to the universe, and that is a big statement which I take very seriously. I have done a lot of research and conceptualize things very well, but I haven't been conventionally educated in any of these subjects past entry college level.

This coil has the potential to be much more than a speaker, it has applications in every science imaginable. The fact that it heats up may be due to the fact that there is no resistor in that circuit, but what I'm trying to say is that in order for this coil to be used as a speaker, it needs to be engineered for that purpose. Not just the coil itself but HOW you use it.

There have been experiments done with the coil and they have showed that for some purposes, it is actually much more efficient than conventional toroidal coils. They made a ceiling fan that was 600% more efficient than a regular one, its easier to use it as a motor than a speaker currently.

If you doubt the potential of this coil, take a look at this and give me an explanation:

This is just one anomaly, there are many.

I don't have the capacity to put in words how I understand all this, I'm trying to get it out there so people can play around with it because that's what needs to happen in order for anything to come out of it. But you'll have to do your own research if you want to make it happen.

It's very unfortunate that most people I show this to do not even take the time to try and understand it. I wish I were able to get it across just by telling people. Maybe one day. Either way, I'm gonna stay focused on it and see what I can make of it.

Send me one and i'll test it.I have 500 watts a measurement mic and a impedance tester.

I feel a Douglas Adams reference coming on. :rolleyes:

My god, a metal ball spun to very high RPM kept spinning on a low friction surface?!?!
