THX, The Standard for Theatre Sound
THX is a set of technical standards developed 15 years ago by Lucasfilm to ensure that moviegoers see and hear films as
the director intended. This comprehensive set of standards includes rigorous specifications designed to optimize
equipment, room acoustics, background noise levels, and projection and viewing angles.
The THX Sound System was developed in 1982 during the production of Return of the Jedi. Lucasfilm’s technical experts
began to consolidate existing performance standards into a new system which included theatre acoustics as well
as sound
reproduction equipment. THX (named after Lucas’ first feature film, THX 1138) is a sound system designed specifically
to reproduce film sound exactly as it was recorded by the filmmaker.
The system was created to complement advances made by Dolby Laboratories in encoding and decoding sounds in the
sound track. The THX Sound System concentrates on the playback chain from the decoder through amplification,
speakers and theatre acoustics.
A certified THX theatre carries several important advantages for the moviegoer. The audience enjoys a more naturally
balanced sound that uniformly reaches every seat in the auditorium, improved dialog intelligibility and decreased bass
distortion. Better stereo localization makes the sound appear to travel across the screen with action. The result is the
reproduction of the same clear, dynamic sound originally created by the filmmaker.
In 1985, Lucasfilm’s THX Division began researching the reproduction of movie soundtracks in the home. Testing
revealed a startling difference in sound quality and character between home theatres and THX theatres. Home THX was
created to solve this problem.
Circuitry was designed to accurately translate the sound from movie environment into the home, correcting the tonal
and spatial errors that occurred. Then refinements in designs were researched: most hi-fi equipment was designed to
reproduce only two channels of sound in home, not the four, five or more channels present in a movie soundtrack.
THX certified speakers are designed to provide accurate reproduction of the soundtrack in the home environment.
