10.2 surround sound

10.2 is the surround sound format developed by THX creator Tomlinson Holman of TMH Labs and the University of Southern California (schools of Cinematic Arts and Engineering).

Developed along with Chris Kyriakakis of the USC Viterbi School of Engineering, 10.2 refers to the format's slogan: "Twice as good as 5.1".

[3] Lack of vertical information has long been considered one of the largest obstacles to realistic sound reproduction.

The ".2" in 10.2 refers to the fact that an additional Low Frequency Effects channel is added, not just a second subwoofer, to enhance the sense of envelopment.

A 10.2 surround sound system was demonstrated at Audyssey in Los Angeles and at Bjorn's Audio Video in San Antonio, Texas.
