THX is the abbreviation of Tomlinson Holman Experiment, which is not a sound standard like DTS or Dolby digital sound. It is a kind of certification, which is formulated by Lucasfilm to ensure the quality of home theater design and provide complete quality specifications for home audio-visual equipment (home theater).

THX standards are different from international standards. Most standards have a tolerance range, but THX has no tolerance, only a minimum requirement, which must be exceeded before it can be qualified, thus eliminating artificial tricks. In addition, thx is short for thanks, which means thank you. ?
