Folded in to a pleated shape to create a massive radiating area, edges glued to housing, electrodes placed... equates to superior headphone?
This logic is inspired by the TakeT H2, but would give us the ability to NOT include some of the odd design choices made in that headphone (cheap housing, 3 way with asymmetric placement of drivers, headband, etc), as well as create something that does require an arm or leg for payment.
In any case, I obviously do not have much in the way of answers, but I definitely think this is an avenue of driver design that should be explored by the DIY community... mostly due to the ease of construction and cheap cost of the material. If the H2's are any indication of the possible sonic advantages of a pleated piezoelectric film, extremely high transient response being the major attractor, then this might be worth pursuing.
*edit*
It seems that the H2 does indeed use PVDF in it's drivers... it's folded in to the pleated shape, because when the film is charged it expands/contracts or decreases/increases the size of the pleat cavities ergo moving air and creating sound. It's detailed here: http://www.taket.jp/tech/tech.html Though I must say that it's incredibly hard to read... there is also mention of using multiple films but that section is so garbled that I can't understand what it's getting at. Maybe some one who knows Japanese might have a better idea?
