[QUOTE="John Roberts, post: 83837, member: 126"] Re: New speaker tech.. *Graphene* Not to be even more pedantic, DC sound is wind. Sound is wave motion that involves air moving "back and forth", (like I said). Speakers waste a lot of energy moving a relatively heavy cone and VC back and forth, with imperfect coupling to the nearby air. Moving air at distance is the desired result. The obvious energy saving is to cut out the middle man, stick a small transducer in the outer ear, or bypass the mechanical system completely and wire electrical signals directly into the auditory nerves. ----- This parade of ways that Graphene is changing the world, seems like a creative writing contest between some PR wonks.
