I remember originally the driver housings were going to be ceramic, I see that it has changed to ABS now. Can you elaborate on why you ended up making that decision and how it will impact sound. I was impressed when I saw you would be using ceramic because it is difficult to manufacture, more expensive, and potentially prone to breaking. All also reasons that I assume contributed to your decision to change. But ceramic is much more stiff and if the right composition is used, and it is well tuned noise can be pushed out of the audible range.
