Sounds like Thunder

Conventional loudspeakers produce sound by vibrating back and forth, but new speakers made from sheets of carbon nanotubes create music the way lightning generates thunder. When an audio-frequency electric current was applied to stretchable, flexible transparent films of 10-nanometer-thick carbon nanotubes, physicists at the Tsinghua-Foxconn Nanotechnology Research Center in Beijing unexpectedly discovered they could make sounds as loud as commercial speakers. The scientists reason that the electrified nanotubes heat and expand the air near them, producing sound waves. These loudspeaker membranes can be stretched up to twice their original length without breaking and with little change to sound intensity. These sheets could be placed over paintings, windows, video screens—even in clothing, the researchers say, as a means to keep a person warm. They even put their handiwork—described online October 29 in Nano Letters—on a waving flag.

once I learned how nano tubes worked, and how they are made, one thing I always wanted to see was some speaker cone that is paper thin, yet as strong as steel many times thicker, yet light as air just about, woven like carbon fiber to be used on some insanly large speaker.

Make like a 40" flat panel woofer that has a cone as light as a 6.5" cone, and have 1 large motor behind it backing it up

Imagine the pressure, and the lowsssss

But then reality kicked in, and realized it would probably cost thousands and thousands of $$ for just the cone to be sampled... lol

would be nice though....
