Martin O’Donnell pointed out an article from New Scientist that says Nerotek has developed an integrated home theater speaker system that delivers surround sound from a single point in the room. According to the article, the Niro 1.1 Pro achieves the surround sound effect by placing five speakers in the same box and using signal processing to alter the sound so that you hear it coming from different places.
I had to Google around to find info about this company. They’re at www.niro.net.
