capable of generating greater than 120dB SPL of frequences from 20Hz down to less than 1Hz!!! Read more at http://www.eminent-t ech.com/main.html. This video is the first time this invention has been shown. You won't be able to hear the low stuff on your PC speakers, they won't go below 30-40Hz for sure! The fan self-noise is filtered out in the production enclosure.
At AES Exhibition Oct 2009 - you can see how much the TRW fan blades deflect under a loud signal from the amplifier. Watch the laser reflection elongate and shrink according to the TRW volume.
