Say goodbye to cables and speakers all around your room - a new technology using only one speaker to produce surround sound is unveiled by Nirotek. NIRO 1.1 PRO DVD player uses 5 speakers in a single case, and an algorithm that fools the brain.
With 600 million calculations per second, it changes the signal to each speaker twisting the perception of the direction the sound is coming from.
The company says it is not required for the listener to face the speaker. The system costs $799 and can be found only online. Source
