[QUOTE="Ron Kreiger, post: 16317, member: 68"] Re: Coaxial Wedge Collaboration There are several high output , high SPL Planar Ribbons available in the marketplace. The Stageacompany one comes to mind first that is readily available as a single priced unit. [URL]http://www.stageaccompany.com/en/products/ribboncd.php[/URL] It is pricey however. Also SLS has some but I'm not sure if you can buy them as individual components. [URL="http://www.nczon.com/Planar%20Ribbon%20Technology.htm"]http://www.nczon.com/Planar%20Ribbon%20Technology.htm[/URL] Alcons has them as well but again the price is fairly high and I am pretty sure you can only source them as an OEM and not by individual pieces but I am not 100% certain of that. [URL]http://www.alconsaudio.com/site/technology.html[/URL] Piega a company out of Switzerland has shown a bunch of press a few years back when they started making their own and using them and if I remember theirs came in at around 111db/2.83V/1m and they needed to seriously pad them down for their applications. Page through the .pdf and you'll find some cool reading regarding the actual development and assembly of a Planar Ribbon.Piega actually hand assembles them! [URL]http://www.piega.ch/download/Piega_Praesentation_E_2010.pdf[/URL] The trick to making a ribbon high power is being able to laminate the Kapton HN like .005'' film with thin aluminum foil around .007'' and then etch the voice coil accurately.Basically when finished it looks very similar to a flexible type circuit heater that would be used in a spacecraft or aircraft except the copper coil is replaced with an aluminum one. It's cool technology but the materials and manufacturing process keeps it rather expensive, otherwise I think a lot of manufacturers would have already been making them.(strictly speaking of the high output/high power handling types) Home stereo units are a dime a dozen.
