The Orion was designed by Segfried Linkwitz, who was also responsible for the Beethoven/Dvorak/Vivaldi line of open-baffle speakers for Audio Artistry. Currently, the Orion project is a grass roots attempt to empower the DIY'er to build a speaker system that rivals any commercially available speaker on the market. Linkwitz sells a comprehensive construction package, which includes plans for building the speaker and circuit boards for the crossover. It's quite an amazing speaker and certainly better than anything else I've ever owned. Cheers, Mike
