Ok a few years ago I stumbled accross this technology and found it very interesting. A speaker powered by an eletrical motor hence elimnating distortion related to the traditional "motor" assemblys used today. They mainly use this for large PA type speakers, bass bins to be exact why hasn't this technology evolved into home subwoofer use. The specs on these things are absolutely amazing and from the looks of it, it takes alot less power to get the same results with these types of speakers. Well whats your opinion on this??? I think this would be a very good discussion to start up. For more on these amazing speakers check out. http://www.servodrive.com/ BTW how many speakers do you know of that can produce enough volume to cancel out the sound of a jet engine??
