squeak, the whole thing about "it looks like it should work" is in relation to the fact that there are numerous companies in this world out to take your money with BS "reviews" that they have, and overhyped marketing plans. *ahem*monster*ahem*. the fact that you cant believe everything the interweb tells us means you have to decide for yourself, or find proof other than what the companies website tells us.
thats all. but the basic principal of sound is the movement (vibration) of molecules... and the best way to move molecules through air is certainly not by moving the cone of a speaker in and out //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
this seems like it would work a hell of alot better than a standard loudspeaker in sub50hz range. but i cant see those fanblades moving any faster than 40 cycles per second while spinning. lol.
and is it just me, or do those fanblades look mighty fragile?
//edit
idea just popped into my head. if some of you still doubt, think about the loudness of helicoptor blades. they are just a really big fan. imagine if that was a controlled sound //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif
i think that puts it into perspective.
