Wow! Thanks for the pics. Great Pics!

Now I don't mind doing some DIY, but that's way out of my leaque. I did Rebuild one of my Maggies Ribbons with their DIY kit. Got it on the first try, but talk about stress, that foil is so thin and fragile, a steady hand is a must.

Really great work you + your Buddies have done!!
A few pics looked like some Perforated steel stators with a grid pattern on them. looked like another pic had a grid similar to Acoustat as well. So a few people running Stat's with the Ribbons.

So on your ribbons you have 3 strips are they backed by a single piece of Mylar? Will ribbons have the ability to go lower if they have a Mylar backing?

I do plan at trying my hand at some DIY Acoustat Panels in the future, already have alot of Mylar and Moray James was kind enough to make a jig up for me to wire the panels. I just got to many things on my plate right now. But I finally have a shop now to work out of, hard to do in my small apt.

I look forward to see your progress on your DIY bass panel for your Tympanies, be sure to take lots of pics!

:O)

  Reading old posts about building replacement panels for Acoustats. I have 4
  1+1 panels 3 are is perfect working order the other melted when applying a
  heat gun. Now I am interested in rebuilding the 1 pair . Do you have steps
  pics, parts list etc. to rebuild a pair to drop back into original frames.
  not looking to rebuild as original want the best sound from 80 hz to 20khz

  Sure will.
  I will probably make a transducer that has uniform piston motion.
  I already have design ready for it.
  But it all depends on how restless I will become to get the Magnepan/DIY ready.
  My piston design will take longer to make as I still have to buy the silicone surround suspension.
  And no, I will not give You the design specs on the piston planar. hehehe
  The building specs for LaFolia is free to find on the net.
  Cheers!

Thanks!

Yes, the blue panel is one of 4 panels from the Acoustat MD240 electrostats.
I am stripping them apart using the hole plate as a foundation for the magnets in my next design.
Going to make some smaller surround planars and so I am going to cut the panels half length. They will be around 60cm long that way.

My ribbons are glued to mylar and are able to play a lot lower then a single ribbon but will not reach much above 22kHz or so because of the added mass of the plastic.
That is mainly because it has larger radiating surface that are able to reproduce lower frequencies adequately.

The corrugated ones are made by a designer here in Sweden.

Here You will find a lot of info building a membrane.
But I have yet to measure the frequency exactly. I will come to that.

On one of the pictures You can see the back of a planar bass panel.
It looks a bit different as it uses thick steel lengthwise with added led filled bars.
Vibrations? No way! Hehehe
