You are looking at the current inside a cross section of 3 different wires at different frequencies. Before this we use to guess what the current looked inside a conductor and talk about skin effect but ignore the proximity effect because we could not model it. Read our white paper for more detail. Why do Hollow Oval cables sound better? As the frequency is raised to 4 kHz, non-uniform current distribution appears in the round conductor cable. This change alters the resistance and inductance properties of the cable, an unwanted effect. Why do Hollow Oval cables sound better? The plots at 10 kHz show increased areas of reduced current density for both the rectangular and round geometries. The effect is much more pronounced for the round conductor, which leads to greater changes in its electrical parameters. With our Hollow Oval design, note the uniform current distribution, even at 20 kHz. This is why the electrical properties of the Analysis Plus cables don't change, and why more of the music is delivered to your speakers and to your ears.

Our Big Silver Oval and Solo Crystal Oval speaker cable were the only cables which met NASA’s specs for things like rise time and low impedance, under extremely demanding loads. We are very proud to provide NASA with our cables. This is the letter we received after their initial testing. Hey Mark, Searching the speaker wire industry for an appropriate transmission line has been difficult with the rarely posted figures. I appreciate the fast response and shipping. They arrived on Friday, but only yesterday did I get to test the wire types. I unbraided the very ends and attached a stub of flat copper so that I could bolt them on our posts. Our operating condition was 250us to 1ms 120A current pulses at 80V into our laser diodes. That puts our load impedance below an ohm. I’ve attached a photo of the silver oval prepared. The wires performed very well and are a viable substitute for the stiff flat we currently use. The output of Big Silver Oval looked the best and is most similar to our flat wire. Silver Oval 2 showed a little bit of oscillation at the beginning of each pulse but was well within a stable range. These are the only two speaker cables we have tested that meet our requirements. I like that its nearly as small as our flat also (which is 10mm x 2mm). No the application is not confidential. The laser’s a high energy, narrow line-width 2um pulse. It can be used for wind profiling, CO2 measurements, and other things. If you need something official though, I’d probably need to talk with others. I can provide some (attached) but you’ll see in our final assembly that you can’t see the cable itself. We had to wrap it in a neoprene insulator for protection and requirements. We have three sets of these for our system (3 laser pump sources). The cable does work very well for our application. The clamp image is how we translate the oval cable to a high current connector. Our length is about 10 feet. Will order 100 ft of Big Silver Oval to ship to NASA, LaRC, Building 1202, Room 223, Mail Stop 488, 5 North Dryden Street, Hampton, Virgina 23681. Hope that helps, Paul Paul J.
