I ran across this today while researching the demise of one of my favorite computer speaker companies Monsson Audio and couldn't resist posting it here:

"...The TRW-17, In 2006 a new type of sound reproducer, the worlds first rotary woofer was introduced. It has specifications and performance capability like no other woofer on the market. It can reproduce sound from 0Hz to 20hz and is designed to fill in below the frequency range of existing subwoofers. Eminent Technology now faces the challenge of convincing the general public and engineers that we can hear below 20Hz and content exist that can be reproduced."

Enjoy!

Someone posted a link to the TRW-17 in the Exotic Audio forum too. It's an air pump, basically a variable speed fan. A novel approach to modulating pressures under 20Hz.

The little Eminent Technology LFT-16 speakers were at the Great Plains Audiofest in 2005. I saw and heard them there.
