Two new single speaker surround sound systems from Nirotek. Both the NIRO 1.1 and the NIRO 1.1 PRO only need one speaker and a subwoofer to create 5.1 channel Dolby surround sound. Pioneer has something similar; their PDSP-1 is actually a single panel with 254 small speakers that project the sound in different ways to create the effect of surround sound.
