I can, first of all, immediately tell you that it's the real short cut to Hi-Fi Heaven. What makes this project so attractive is it's low cost, extremely hi-fi quality sound, a quality of sound that would normally require at least a 10 times higher investment, coupled with the warm feeling that a home made dream brings to your ears, though as with all things in life you'll have to live with low sensitivity and high power requirements.
Secondly, at a more earthly level, I can tell you it involves the same normal principles behind normal run of the mill loudspeakers, only that instead of using a cone shaped diaphragm, you use a flat stretched out membrane on a MDF fibreboard frame; instead of having a copper coil it uses a long flat thin foil of aluminium foil cut out in a special design, all in a homogenous magnetic field generated by normal flat magnets, these magnets are upon a perforated iron plate.
Thirdly, anybody can build them, with no special skills other than patience, a few tools and aprox. 500 US$, and hard work.
Fourthly, it's a proved principle, used by many different Hi-End Loudspeakers, including the famous brands like Apogee, Magneplanar, among others.
This is more than a mere experiment, it's a proven project with a great amount of knowledge behind it, I personally learnt about this project in Denmark, where this originated. I will quote many articles from Danish magazines, where the project was called La Folia. I can in no way claim authorship of this project, I will just be the first person to put this on the Web, this will extend this collective project around the world, and give us a bigger wealth of experience to build upon.
I will include detailed information on the building of my own La Folia model, which I enjoy everyday. I put to effect a big amount of innovations, which I feel are to a certain extent original and different to the danish projects that I include. I have been out of Denmark since 1990, so I have not had access to Danish innovations, I expect some danes will contact me with more info. I will include a section on this page to deal with the comments.
