For those interested in replacing bass ribbons with readymade ones I recently replaced a pair of 20 years old GRAZ Duetta sig bass ribbons with
Clarisys versions.They appear to be excellent quality,at least on a par with the GRAZ ribbons.The GRAZ ribbons were suffering from variable stretching in certain areas leading to the dreaded kazoo resonances.The Clarisys ribbons are performing excellently.I took the oportunity while
replacing the ribbons to impliment an idea I had about the edge damping.The edge damping supplied by Clarisys is felt which is about 50% wider
than original so the rebates have to be widened.I modified the felt by adding 1mm thick polyetheline foam underneath.On the slant clamp I made
the rebates a further 6mm wider than the tensioning clamp filling the gap with foam.I figured the asymetric damping might do a better job of suppressing resonances.

The old Clarisys site is not working anymore. Here is the new one: www.clarisysaudioglobal.com
The Apogee´s are found at the bottom of the site.

WOooow they got some nerves here a quote.
"Why settle with listening good sounding music if you can listen to the extraordinary sound of music.
Owners of these speakers have switched to the extraordinary
"Clarysis Audio Ribbon Loudspeakers"
Borrensen, Magnepan, Alsyvox, Evolution Acoustics, Apogee Acoustics, GT Audio, Bayz Audio and Focal. "
Au what a lame thing to do. and say Apogee.. they clearly copied. what a ******* basterds. (ribbon ? where, theres a tweeter the rest is clearly a planar magnetic) they hope people read it as there speakers are better then all of these. just by saying people had one and now use theres.. thats some lame method of promoting there product.
well i heard them once, to much bass and a tweeter that blow you ears out. there you go. besides that they act like the invented something while there speakers is almost a 1:1 copy of a Apogee.
there specs
So what about the non neo option ? they do not bother to mention,

Oh and please do show a measurement 🙂 we all know thats never going to happen, i mean they are so affordable only 40k , cant expect they measure such things !
speakers is marketing sale ,there is no speaker the best.
find A goeroe,and you sold it 😀😀

Because we can build it for less than what they sell it for, our opinions tend to revolve around that.
I think their prices are extreme but then again a rich doctor with more money than brains
doesn’t care about what we already know so there’s another market ready to be filled
Can’t blame them really and they at least provide decent upgrades to older Apogees
if your so inclined so good for them in keeping this arena alive once again

yeah i know i just been salty 🙁 since we know what such things cost. then again i do not like mentioning what they had before. thats in relevant ! and clearly a method to see ours are better, while hurting the others. while they copied a succesfull planar in my opinion with some changes
My first attempt and making a foil panel. @AVWERK thanks for the inspiration... found this neat double-blade that makes cutting the traces much more precise and easy. Long way to go. This is the DVC version from the earlier Scintilla. The last photo is a possible foot / leg when I rebuild the frames / covers.

Heej there narkotic 🙂 i think we had a conversation about this ! well corrugation is usually the hard part 🙁 getting a nice one. people tried printing one , but it usually does not work that well and even when they work a long/wide one is often a problem 🙁.
anyhow i wondered what do you mean by DVC? dual voice coil ? anyhow the dual blade works fine 🙂 i used back in the day sometimes just a thing 1 mm magnet and two blades, but this looks nicer!
About my corugators before you ask, the ones i use are used for rolling out dough, but the companny do not sell these anymore, and the person that pointed me to them and gave me 2 (and i bought 2) and made even couplers on his lathe (to make them 46cm wide), passed away a few years ago, "Craig Hill" me he rest in peace !

DVC on this model we’re 1 or 4 ohm connections of your choice with 4 connections to consider and it makes it
more difficult to do the layout with only 18” width of foil that are available
Great job so far Pete !

Ya man thank you for the chats and confidence! Glad we made a connection and appreciate the confidence boost - being the master of DIY planar!
I will be copying AVWERK's "corrugator" using similar parts. Lucky for me we are somewhat local to each other so when it comes time to corrugate, he will be assisting me. I do understand that is a critical process to get right and was being coy but honestly one has to have that sort of attitude to jump into such a project. Every single step is daunting and the deeper one gets the more fragile things get. So many moving parts.
1. Finding the materials
2. Figuring out a way to get the foil to lay flat on a surface to work with (WD-40 for the win)
3. Figuring out the "trace" patterns. Getting the lines / traces right. Yes, this one will be a replica of the original "1+4 Ohm" scintilla woofer foil, so DVC (2 trace patterns) so can wire it in series or parallel. Much harder to cut than the 1 Ohm version (just horizontal lines vs a combo of veritical / horizontal) and twice the traces.
4. Figuring out a "style" to cut the traces. Everyone has their own style here, different blade types, jigs, etc. It's an art form. Etching / CNC would be awesome but not really in in the cards for this DIY effort
5. Figuring out a way to carefully "lay" the kapton down without any creases / bubbles. Will use a frame and copy AVWERK's idea here (smart!)
6. Corrugating!
7. Then getting it into the frame... scary. Building an entirely new one from scratch here, too. Cost for 1" 4x8 sheet of MDF = $70.
8. TIG welding an aluminum frame / lattice / foot structure
9. Tuning
10. Going fully active 6 channels with DSP (why not)
etc.
This is more of a project to keep myself busy. If it actually sounds good I'd be surprised. lol. It does really build respect for the original Apogee designs.
I have some friends helping, i.e. someone with a CNC router to cut the frames for me, going to do it in 1 piece vs. two pieces like OEM. New clamps probably out of ply instead of MDF. Welcome suggestions on foam to use for the membranes. so many choices... kinda dig the Clarisys "piano felt" style stuff if someone has a suggestion online? Since I'm making new clamps I can cut the rabbit as much as I need to.
The knife is shown in a few pictures I posted earlier.
I think we have good news. Each voice coil measures around 1 Ohm so in series I get 2 Ohms. For some reason I recall people saying apogee wired it in parallel but not sure why, that would drop it to .5 ohms right? I am getting 20 ohms between traces so there is something shorting somewhere but that doesn't sound too critical... thoughts? Now to lay down the kapton!
