capacitor dielectric bias

I've seen speaker cables with dielectric bias.
Why not capacitors, too? It'd be like biasing a transistor to reduce switching noise.
is this wacky?
If it's possible I want a a piece of the action, after all it was MY idea!

Its already being done -JBL does this in their Everest - so your too late with that patent filing :-)

Vandersteen, among others, also uses a DC bias on some of his crossover filter caps.

Here's a pic of the 5A crossover with its 27V. stack of 9-Volts.

Biasing of electrolytics is even more critical than that of film. If not biased, they will distort. This has led to a bad reputation for electrolytics, one not deserved if they are actually treated properly.
