Right now, Eminence has built a prototype version by simply machining a place for the shorting ring, and they've added steel to the core to bring the flux up to original spec. That also means the cooling vent is now made 0.75". They intend to test the driver and see if it meets requirements, and if so, we can go into production immediately. If not, there will be another prototype built that places the shorting rings in the plates allowing for a larger vent. This second approach would require an additional eight weeks of development time, and could increase the cost. So we're keeping our fingers crossed that the first prototype meets specs.
