I was looking for the source that said that Mylar was less resonant than Kapton, but couldn't find it. I did find an old post from Mart at Planar Asylum to the effect that Magnepan uses Mylar because it's less expensive.
By the way, I just saw the price of the Genesis 1.2 -- $235,000! Guess I won't be using them for surround. :-)
