Thanks for the response which makes it clearer where you are coming from. I still cannot believe in my gut that anyone would be prepared to go as far as you claim in convincing themselves.

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

After ripping on the youtube vid originally this might not be my place but lay off the guy.

I think you may not be seeing what is there. I am responding to what he has posted and asking civil questions because I am genuinely interested in what he has to say. I am repeating an unanswered question in the hope his apparent honesty will oblige him to respond which it has in the post below.

As for reasons why most will want to believe in these things they are technically illusions IMO, people have no solid reason based on their education/experience not to believe something they want to believe in so they do. Modern times have become so complex that a very, very tiny percentage of humans are actually able to be on the cutting edge of understanding.

I agree with the thrust but would dispute that modern times are significantly more complex (if I have understood what you mean by complex) than they were a few decades ago. What has changed is primarily social. People are continually bombarded now with lies and misleading information in a way they were not when I was young. Learning is increasingly achieved by by rote, following recipes and templates and not by being taught principles and understanding. The status of rational versus irrational thought has shifted a great deal. Etc...

However I believe as a species we have a drive to understand such things and this drive is not limited to those with a very high intellect/education level.

I would partially agree but would dispute that the OP is seeking to understand. He intuitively knows that "it" is true and is seeking confirmation which is not the same thing.

Combined with fact that there are even fewer opportunities in societies as large as ours for someone to standout and I think you could see the desire to be on the forefront of something like this.

I agree with the desire but surely things like the internet give pretty much everybody the opportunity to standout to some extent?

What does it matter if what he believes doesn't jive with personal beliefs or reality :rolleyes:.

It matters mainly because the OP thinks differently to me and understanding why is interesting and partly because of the role active followers like him are increasingly having in shaping society.

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

This "discovery" is not coming from a place of science, it is science that is supposed to be able to make something of it. They won't use terminology the way your used to hearing it. I AM interested in what these obvious holes and flaws are. And to repeat myself, I don't see anything standing out that's wrong with the idea. I believe it because it illustrates ideas I have had since I was a child and have been searching for in the real world, such as numbers formatted in a way where there are no approximations or guesses at what something is. Something self-evident. It's always great to be educated, but you can educate someone for years on something incorrect and they will still understand it. That doesn't make it absolute, the people that came up with that were still just people and the reason their work has become accepted it because people go along with it because its the best they have at the moment. But I don't think a true solution or unified field theory is going to show that numbers work they way we have made them to work in our heads thus far.

After ripping on the youtube vid originally this might not be my place but lay off the guy. Those of us educated in these fields see all of the obvious flaws and holes in the reasoning (and complete lack of solid evidence, and the inherent unintelligibility of many of the claims) but people have been sold on snake oil since things have been for sale.

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

If you are really interested, you'll do what I did and find everything you can on the subject.

I am interested in why you believe in the subject. I have little interest in the subject itself beyond it's general classification and what parts you are latching onto.

I know Marko is a horrible presenter, here's his student, who might be a little better at it:

http://www.youtube.com/watch?v=7pvuTZ5u6Kg&feature=relmfu

That's part 1 of I believe, 16.

In watching these videos, you must keep in mind, they are slow paced, and if you are looking for ways to tear it apart while watching it, you are wasting your time.

Errrr...

"can model a previously unobserved invisible energy"

Invisible? What does energy taste like, what does it feel like? Unobserved using the scientific method but observable by those with faith? There is a name for this. (I have not watched more than the first few sentences so do not know who can or cannot observe it).

"Energy is referred to by many names...[list of things most of which are not energy but sound good]"

We can conclude that the author does not know what the word energy means nor, probably, the list of words that sound good.

"It is the motion driving force behind all of reality."

Energy is now a force. Surely you know that energy is not a force from your school days?

"It is the initial impulse positive force behind creation"

Still a force. Consistent for 2 sentences albeit consistently wrong.

"Energy is characterised by its linearity it moves in a straight line"

How can a single scalar quantity be linear or nonlinear? Quantities are linear or non-linear in the context of governing equations.

Some of the quotes may be slightly off but it is not worth the effort to get right. It is like those nonsensical sentences of key words that spammers sometimes post.

Can you really see none of this? Or do you see that some of it is wrong but consider it unimportant?

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

I apologize, but I really can't prove this math to you myself. If you are really interested, you'll do what I did and find everything you can on the subject.

Take whatever you can from it, I'm not saying you must believe everything said. Once you see enough "coincidences", it might start to click. I remember when it clicked for me, I've never thought about the world the same way, and I see evidence of all this in my daily life.

The answer and the question can't exist in the same universe at the same time. And sorry for the inconvenience.

BTW, The Hitchhiker's Guide to the Galaxy was a 5-book trilogy (and video game), long before it was a movie. Consider reading.

Actually I didn't watch the movie. All I know from Douglas Adams comes from Graham Chapman's book, "A Liar's Autobiography".

I first knew it as a radio program in the 70s (on the BBC in the UK). The books came afterwards.

The Rodin coil is not required for speakers. The r-coil can create a strong, linear field but it requires a large amount of wire and power. So, would it be better to justify the negatives?

A traditional circular coil creates a torriodal-shaped field, arching around the top and bottom with it straight inside of the coil. But given the small amount of movement required, even of a subwoofer of less than half-an-inch, and that the coil is within the magnetic field (unless underhung) for it's entire length of "usable" travel, for all practical purposes, the forces are approximately axially linear. The surround and spider are required with both coils to limit travel and provide restorative forces, and are more than capable of controlling the non-axially linear forces from a traditional speaker motor.

The amp side of the story may be an entirely different issue. I don't know what the reactive inductance characteristics are, or the resistance, and it may require a different output stage to drive the speaker without problems.

If I were to build a r-coil speaker, I'd use a small neo magnet mounted to the cone and the coil fixed. Either way, the mass of the cone may limit the upper frequency range. IOW, don't expect a Rodin tweeter anytime soon.

IMO, although it's possible, it's not practical. But of course, you're welcome to prove me opinion wrong.

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

Thanks for your response although you have skipped perhaps the most important question: hasn't anything this chap is saying seemed wrong to you?

I believe it because it intuitively makes sense to me with what I've gathered from my own personal research.

Thanks but the interesting question still remains why it intuitively makes sense to you? You must be aware that most people following your links do not see what you see and nobody that understands the meanings of the words used by the chap in your video will do anything but smile. Why do you appear to disregard the views of those people that know more than you do about the subject and put your faith in other sources?

> He HAS been supported by people with credibility, people from NASA,
> Microsoft, and others.

What form has this support taken? Letters, meetings, money,... (I am not wholly unfamiliar with the topic because a few decades ago my father was in charge of forward planning for a company involved in electrical power engineering. He was the contact for slightly more developed examples of the chap in the video as well as more rationally based projects.)

> It's just not easy to apply because it requires you start from scratch..

Why do you say it is not easy to apply? It would appear easy to apply both in terms of constructing prototypes and in terms of theoretical models. About the level of an engineering undergraduate project. The most difficulty would seem to rest with defining what "it" is (which is of course a clue).

If we need to start from scratch it would follow that our current knowledge is wrong or inadequate. Are you are aware of an experiment that shows that predictions based on our current understanding of electricity and magnetism are inadequate? To your satisfaction and/or the scientific method?

People would fall over themselves to get involved if even a hint of what you appear to believe had a sliver of evidence to support it. Look up cold fusion for an example. The problem would seem to be that sliver of evidence.

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

Well, I put it out there, that's all I intended to do, I'm not here to try and convince you of it's validity, that's up to you.

It's just not easy to apply because it requires you start from scratch.. No one seems to like the idea of that or seems to accept that that's what will be necessary to continue scientific progress without making up the universe as opposed to learning from nature.

Can this be used to improve the output of my Capissen 38 engine? It keeps falling right out of the sky... :(

Yay! Another Firefly fan! I really do miss that show. On a related note, I have also heard rumors that there may be a sequel movie now that Joss Whedon has really made a mega-blockbuster.

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

What I would like to see is how this coil winding compares to a simple solenoid, like that of a voice coil. A toroid is a lousy comparison, as the net winding is in a completely different orientation.
