Blaine, those alloy diaphragms go into the Compression Drivers.
we make Compression drivers with a 1.75", 3.0" and 4.0" diameter diaphragm (the touring sound industry needs these things to project a couple hundred feet outdoors)
I leave my Credit Cards in the Truck outside otherwise our Gaussing Machine would blank em out..
We have a 10,000 KJ gausser that will gause Neo at 22,000 Kilogauss (total metal saturation) so you really have to watch out.
We purchase the Baltic Birch is standard 4.8 sheets usually a container at a time... it is then layed out on the CNC cutting table and cut for minimal waste, then routed and formed, glued, fastened, etc.
after that we either Line-x it, or paint it in black or white, depending on the application
