Below are the images illustrating how it will work at the first test-stage.


Hey, I kind if did it….

The first draft of the experiment with Vitavox S2 driver is on. The idea to use a combination of permanent magnet and electromagnet was abandoned. The filed coil was calculated and built by Bud Purvine from Seattle’s Netics Ltd. The magnet core was manufactured from 12L14 material by Erickson Machine Shop out of Boston At 20V and 2.3A it runs approximately that same magnetic force as the Vitavox S2 has with a permanent magnet. I did not listen the thing yet and probably will not for a week or so. I will keep the readers of the site informed about the final results and conclusions and the measurements that I might be conducting. I would like to point out that it will be the only one know to me methodologically clean experiment if an electromagnet driver has any advantages over a permanent magnet as no other elements of the drives were changed.

It will be fin to listen this thing…
