I was intimately familiar with DDS for a number of years before I retired from live audio about 8 years ago. Their factory was a half hour drive from my home, and I would drop in now & then to BS with Pat and Bob (the original owners). They would emerge --or, float-- from their shared office, usually followed by a billowing cloud of smoke. They even did some TEF analysis for me on a monitor I designed using one of their horns and McCauley drivers. (The McCauley brothers, also in this area, were another story....)

In reality, the designs are ambitious but the projects are not. When I'm satisfied with these loudspeaker systems on paper (there's a couple more on the drawing board), I will simply share them with the Forum in appreciation for all the help I've received here toward their development. I can't afford to build them myself, but if anyone sees any promise in my amateur doodlings, they are free to build and modify as they wish!
