SANDWICH-DOME

With CVD diamond and alpha corundum ceramics we have already two of the very best membrane materials on earth, so why search for a new one?

Let's summarize it: CVD diamond is definitely the best material available. It's stiffness to weight ratio is unsurpassed, the internal sound velocity unrivaled. However, until today, we can only make tweeter and small midrange units, cost and serious technical problems prevent the manufacturing of larger cones. It is quite similar with ceramic domes, these are second to and almost as good as diamond (still better than anything else exept diamond) but also restricted in size. The largest dome we can feasibly produce is a 160mm dome for the C220 series.
