THX was developed by Tomlinson Holman at George Lucas's company Lucasfilm in 1983 to ensure that the soundtrack for the third Star Wars film, Return of the Jedi, would be accurately reproduced in the best venues. THX was named after Holman's initials, with the "X" standing for "crossover"[2] or "experiment". The name is also an homage to Lucas's first film, THX 1138 (1971). Deep Note was created by Holman's co-worker James A. Moorer.
THX is a quality assurance system, not a recording technology. All sound recording formats, whether digital (Dolby Digital, DTS, SDDS) or analog (Dolby Stereo, Ultra Stereo), can be reproduced in a THX system. THX-certified theaters provide a high-quality, predictable playback environment to ensure that any film soundtrack mixed in THX will sound as near as possible to the intentions of the mixing engineer. THX also provides certified theaters with a special crossover circuit whose use is part of the standard. Certification of an auditorium entails specific acoustic and other technical requirements; architectural requirements include a floating floor, baffled and acoustically treated walls, non-parallel walls (to reduce standing waves), a perforated screen (to allow center channel continuity), and NC30 rating for background noise ("ensures noise from air conditioning units and projection equipment does not mask the subtle effects in a movie's soundtrack").[3]
On June 12, 2002, THX was spun off as a separate company from Lucasfilm[4] and sold to sound card manufacturer Creative Technology Limited, which held a 60% share of the company.[5] Under Creative Technology, the company developed several further innovations, such as the first THX-certified audio card for computers, the Sound Blaster Audigy 2. In 2016, THX was acquired by video game hardware company Razer Inc.[1][6]
On September 12, 2024, THX announced Tuyen Pham as Chief Executive Officer.[7]
History
Tomlinson Holman, a skilled audio engineer and scientist largely responsible for the design of the theater, had become an employee of Lucasfilm in 1980. In the process of enhancing the setup for the new Sprocket Systems theater, Holman and Lucas invented a complex system that arranged speakers to best fit the architectural space within the theater. Using an intricate crossover network that integrated equipment with the room's unique acoustics, it became perhaps the best quality system anyone could remember hearing. Sprocket Systems mixed the Return of the Jedi sound in the room, the first Lucasfilm production mixed in Northern California. Visiting filmmakers and studio executives were astounded at what they heard. Jim Kessler, who hired Holman, thought of calling the system "Tomlinson Holman's Crossover", or, as originally abbreviated, "XVR". He then changed the "VR" to "TH", but he realized that was the name for George Lucas's first film, THX 1138, and found that would be a fitting name. They eventually changed the "X"'s meaning to "experiment".[8]
Four movie theaters in the United States fully installed THX sound systems, becoming the first THX-certified theaters. To introduce the new system, James A. Moorer created an ear-catching sound called the Deep Note.[9] THX was dedicated on May 20, 1983, and the first trailer and Deep Note premiered on time with the release of Return of the Jedi in theaters five days later. It was billed as the first advance in motion picture loudspeaker systems since 1948.[10]
In 1990, Lucasfilm unveiled the Home THX Audio System at the Consumer Electronics Show in Chicago.[11] That year, a demo LaserDisc dubbed Wow! was unveiled. It featured various clips from Star Wars, Indiana Jones, and Willow.[12] Three years later in 1993, the Special Edition cut of The Abyss became the first laserdisc to receive the THX certification.[13] In 1995, the Star Wars trilogy became the first THX certified VHS release.[14] In 1997, Twister became the first digitally mastered THX release on the new DVD format.[15]
In early 2002, it was announced that Lincoln became the first auto company to offer THX-certified premium car audio systems. A concept sound system for the Lincoln Blackwood showcased the potential for in-car multi-channel surround sound, demonstrated at the THX booth at the Consumer Electronics Show in Las Vegas. The license ensured that high-performance audio systems in Lincoln vehicles met the exacting sound quality and performance standards of its new THX Ultra Premium Car Audio program, beginning with the 2003 Lincoln LS, which was introduced later that year.[16]
THX separated from Lucasfilm and became an independent company in June 2002.[17] The company's headquarters continued in Marin County, California, with offices in Burbank and plan for international expansion. It expanded into gaming and car audio systems. On the professional front, THX planned to continue the expansion of its theatrical certification programs as it became more involved in digital cinema.[4]
On September 30, 2003, THX announced its seal of approval for video game audio. Electronic Arts became the first company to achieve the game certification. This helped improve game sound, measuring the credibility of games at a time when the industry became important to the entertainment market. Five games by Electronic Arts, including Need for Speed: Underground, Medal of Honor: Rising Sun and The Lord of the Rings: The Return of the King carried logos on their box and pre-game trailers.[18] In 2020, THX Certified Game Mode was introduced, with enhanced contrast and color, and reduced input lag, and greater accuracy to the producers' intentions.[19][20] It has judder and smear reduction, meaning that the picture remained crisp with a quick rise time between dark-to-light transitions.[21] On August 3, TCL Technology revealed the first television to include THX Certified Game Mode, a 6-Series TCL Roku TV.[22]
A 3D product certification called THX 3D Display premiered in 2010. The first 3D television to feature this technology is the LG Infinia PX950 Plasma HDTV series. To earn the new THX 3D Display Certification, the PX950 passed more than 400 laboratory tests evaluating left and right eye images for color accuracy, cross-talk, viewing angles, and video processing performance. The PX950 had to pass THX certification for picture quality in 2D, which is required for THX 3D certification. Viewers can select THX 2D or 3D cinema modes for 2D or 3D movie experiences from broadcast sources and Blu-ray discs.[24] Four new THX-certified 3D JVC projectors were unveiled during this time. These were the Reference Series DLA-RS60 and DLA-RS50, marketed by JVC's Professional Products Company, and the Precision Series DLA-X9 and DLA-X7.[25]
In early 2013, THX unveiled a new app called THX Tune-Up in time for the Super Bowl, available on the Apple App Store and Google Play. It was billed as the company's first mobile app.[26]
On March 14, 2013, THX filed a lawsuit against Apple Inc., alleging patent infringement, in a federal court in Northern California.[27]
THX expanded to China in 2014 with new offices in Beijing and a partnership with China Film Group Corporation to redefine the cinema experience. The first THX Certified China Giant Screen (CGS) auditoriums opened in Shanghai in September.[28]
In December 2014, THX teamed up with Warren Theatres, opening a large theater complex opened in Broken Arrow, Oklahoma on December 23. Each of the 18 auditoriums in this theater was THX certified and two new Grand Infinity Auditoriums were introduced. They were designed by Bill Warren to revolutionize the large format movie-going experience. These auditoriums featured THX Certification, patented deep curved screens, 64-channel Dolby Atmos sound and the first 4K laser projector in the United States.[29]
The company was acquired by Razer Inc. in October 2016.[1]
The first THX-certified laptop was released in 2017, the Razer Blade Pro.[30]
THX introduced Spatial Audio in 2018, a new positional audio solution for an immersive 360-degree sound experience through headphones and speakers.[31] The technology was used on the Kraken gaming headset for simulated 7.1 surround sound. These headphones were included with a Spatial Audio app. This would be later used on Windows 10 devices.[32]
On May 2, 2018, it was announced that over 200 Cinemark XD locations in the United States and Latin America would feature a THX sound system. These auditoriums featured large wall-to-wall screens, 2D and 3D digital projection, immersive, surround sound, premium seats with Luxury Lounger electric recliners, and THX Certification.[33] Both companies had first announced the partnership one year prior in 2017.[34] The first THX Ultimate Cinema debuted at Regency Westwood Village in Los Angeles in 2019. This theater provided exhibitors with a branded and differentiated PLF offering that included projection technology from Cinionic, and an immersive audio system, acoustics, and auditorium specifications that met THX certification standards.[35]
In September 2020, Walmart stores began to sell Gateway laptops and tablets, which were tuned by THX, ensuring brighter contrast with more rich vibrant screen colors. They combined style, performance, and value in a wide range of products for consumers, students, and creators. The laptops featured THX Spatial Audio that delivered an authentic 7.1 surround experience through built-in speakers and attached headphones.[36]
THX premiered its first consumer electronic product called the Onyx in 2021, a mobile headphone DAC and amplifier using THX AAA technology.[37]

THX's mascot is a robot named Tex, created by John Lasseter, the former head of Pixar Animation Studios.[44] He first appeared in the original and extended Tex trailer (simply known as Tex 1 EX), which premiered in theaters with Independence Day on July 3, 1996, in which he fixes up the THX logo.[44] A second trailer, Tex 2: Moo Can (often called just simply Tex 2 or THX Moo Can), in which he uses a moo can to perform the Deep Note, premiered in theaters on November 26, 1997, with Alien Resurrection.[44] Less than a decade later on June 9, 2006, the Tex 3: Action (often called just simply Tex 3) trailer, in which he escapes from a car, premiered with the release of Cars. These trailers were later seen on prints of early Pixar animated films on DVD including Toy Story, A Bug's Life (post-2003 only), Toy Story 2 (excluding the 2-Pack & Stand-alone DVDs, which have the Broadway trailer instead), Monsters, Inc., Finding Nemo and Cars. The Incredibles is the only exception to this, as the original DVD releases have the Cavalcade trailer instead. The Tex trailer can be spotted on the majority of Pixar titles, except for Monsters, Inc., which has Moo Can. The latter trailer can also be spotted on these Pixar titles, but it also appears on some 20th Century Studios Home Entertainment DVDs, such as Speed 2: Cruise Control and The Day the Earth Stood Still. Tex 3: Action, unlike the previous two trailers, was only spotted on two titles, those being District B13 and Brave Story. The trailers are also available on various THX demo discs. A fourth trailer featuring Tex titled Tex vs. the Robot, in which Tex and another robot named Bob try to place an orb into a socket in a spaceship, premiered on THX's YouTube channel on June 25, 2020, as a demo for the company's Spatial Audio technology.[45]
The Deep Note was partially previewed on the opening track of the 1983 album The Digital Domain: A Demonstration, where it was included among sound effects that were combined with the Deep Note itself. The Deep Note debuted later that same year at the premiere of Return of the Jedi in LA.[47]

A home cinema, also called a home theater or theater room, is a home entertainment audio-visual system that seeks to reproduce a movie theater experience and mood using consumer electronics-grade video and audio equipment and is set up in a room or backyard of a private home. Some studies show that films are rated better and generate more intense emotions when watched in a movie theater, but convenience is a major appeal for home cinemas. In the 1980s, home cinemas typically consisted of a movie pre-recorded on a LaserDisc or VHS tape; a LaserDisc Player or VCR; and a heavy, bulky large-screen cathode-ray tube TV set, although sometimes CRT projectors were used instead. In the 2000s, technological innovations in sound systems, video player equipment, TV screens and video projectors have changed the equipment used in home cinema set-ups and enabled home users to experience a higher-resolution screen image, improved sound quality and components that offer users more options. The development of Internet-based subscription services means that 2020s-era home theatre users do not have to commute to a video rental store as was common in the 1980s and 1990s.
Surround sound is a technique for enriching the fidelity and depth of sound reproduction by using multiple audio channels from speakers that surround the listener. Its first application was in movie theaters. Prior to surround sound, theater sound systems commonly had three screen channels of sound that played from three loudspeakers located in front of the audience. Surround sound adds one or more channels from loudspeakers to the side or behind the listener that are able to create the sensation of sound coming from any horizontal direction around the listener.
