I notice with the Z-Flex surround, it's very pliable and more so than any roll type I've seen. The radial oriented flutes seem to aid that, and at very high output levels and taking high frame-rate video the Z-Flex seems to allow the aluminum cone (also some more advanced Uni-Q with similar radial pattern ribs) to maintain it's parabolic profile at high excursion.
Nice engineering. I recognize the value of finite element analysis (FEA) in developing and refining these sonic features, and appreciate the result.
What isn't mentioned in the blog entry is how there has been a continuous trickle-down of technology from the top end Blade/Blade 2 down to even the Q series. As complex manufacturing techniques can be scaled-up to lower cost per unit at higher production rates, customers at every level benefit. I can't wait to see what the new upgrade to the R series will bring in Uni-Q development. Should be a show-stopper!
