• OPSIS II uses passive surround sound technology to create the theater surround sound like experience.

  • Passive surround sound technology beam the sound objects to surfaces by projecting audio-wave to surrounding surfaces.  

  • The result is that you can hear the moving objects coming from surround surfaces instead of speaker itself.

  • It is like you had multiple speakers in the same room. 

  • You can enjoy the theater size all around immersive sound in small room with OPSIS II.

  • In the bigger room you can connect two or more OPSIS II together to enhance the surround sound experience. 

  • There is no limit how many OPSIS you can link together only how loud you want to limit.

  • Since the OPSIS use internal Bluetooth signals to connect. You can connect them together anywhere anytime without WiFi.

  •  How effctive the passive surround sound works? This video shows how people react to our technology.
