That right Bobspirt eat your heart out, you wasted tons of money on
speakers and you now..... have a truly inferior system.

Thanks to the navy soon I will be living inside my speaker since my
bulkheads and hull will become my speakers. All thaks to Terfenol-D an
alloy of terbium, dysprosium, and iron metals. The name Terfenol-D
comes from terbium (TER), iron (FE), Naval Ordinance Labs (NOL), and
Dysprosium (-D).


The Naval Ordinance Labs invented and named the material and then
utilized it for higher-powered sonar equipment having greater bandwidth
and reliability. Recent declassification of Terfenol-D brings its
possibilities out of the water and into the audio world with the
introduction of the Induction Dynamics=AE SolidDrive.

All I have to do is epoxy two 2"X3" bars to my steel hull and it turns
that area of my hull into an 8 foot diameter speaker. Great digital
sound that surpassess anything you ever dreamed of. My overhead, decks,
windows, desk all alive with music!!!!!!!!!

Is that the metal the navy used to kill all those dolphins down in
the Keys last week with powerful sonar blasts?

Don't know, did you ask the Navy?

And records show schools of Dolphins and Whales have been beaching
themselfs long before the advent of sonar.

Yet I agree we need to see if there is a link, and if so the Navy
needs to change it's equipment to an all passive style, or use another
form of active pinging.

One word, Joe: resonance.

The stuff mght make a great equivalent of a voice coil, but there's far more
to a speaker than the thing that makes the vibrations happen - it's all
about the thing that vibrates, and the place it vibrates in. If you think a
steel box will make a great speaker cone, cabinet, and listening room, you
have a *lot* (read: nearly everything) to learn about sound reproduction.

Go to your nearest hifi store and ask them for high quality speakers made of
old water tanks. They'll still be lying on the floor, laughing their socks
off, when you walk out with a bemused look on your face. And order a bulk
supply of headache pills - you're gonna need 'em!
