Full range planar speaker using neo magnets

Ya I saw that. I was just very intrigued on something different in their prototype.

They cost a fortune, can't see any prices a bit large as well

I will have to swap ears to find the best layout as I have 2. The A4 size design is only half finished 1 more to build.When I get my carport I will be putting 2 on the wall outside to try. Big ones 4' x 2' with acoustic insulation at the rear.Any suggestions would be appreciated.

Henry,

What made you decide to not build any more Epsilon layouts?

Regards,

Tom

Too much work involved for no return, the difference in the impedance was the driving factor. Which I completely overlooked, which is typical for me, being a right thicko.Too much work all that tape especially at my age, and my back's not getting any younger. The 3mm tape I use now is a lot easier to lay.As long as you run a roller over it which is important with the glue used by the manufacturer. I don't have to cut anymore tape in half or quarters anymore, which is a welcome bonus.I always rush things without giving much thought to important parameters, woe is me!!! Still it keeps me busy and occupied. I will get on with my next rebuild after breakfast.

Latest rebuilds only about another 15 more to go. Latest one on table to make up the small pairs on the floor. Then the 9 blue ones hanging up, will be the next rebuilds. After that a few more here and their.Then I will have to think of something else to build, perhaps an electronic piano layout and then a pair on the wall outside. Or an underfloor loaded full range planar now I have finalized my design after all these years! Should keep me busy and out of mischief.

Have stripped 3 more rebuilds, but I am waiting for some more 12um mylar C. Finally getting organised and making impedance the same within .2 of an ohm. So I get a good pair or a good 9 with the blue ones.Am playing 2 of my rebuilds and they sound great. The tightness of the diaphragm is very important. If not drummy all round you get terrible resonance, so make the diaphragm tight all round. I think finally I have arrived in Nirvana at last. No more re-designs at last.As I said I might make an electronic piano out of 3 diaphragms, should be an interesting and stimulating project.If I lived in a detached house I would build an underfloor loaded full range planar. The bass would sound awesome..I did build cone underfloor loaded speakers but the bass was too loud and shaky for the people next door, plates fell of their shelves.

For the mylar, you can use a heat pistol . I do that with succes ! Thomas Spilcker.

Here is some picture. My english is not so well.

In picture 7 and 8 ( My dog wants to come in, i am busy ) you can hardly see the mylar , but it there. Thomas Spilcker.
