THX Ltd. has spent more than four decades teaching moviegoers to expect the room to move before the film even begins. Founded by George Lucas in 1983 and developed out of Lucasfilm’s push to improve theatrical sound and presentation, THX became inseparable from Tomlinson Holman’s work, James A. Moorer’s thunderous Deep Note, and the kind of pre-movie trailer that made weak subwoofers beg for mercy.
The company’s latest Deep Note trailer, “Spark,” is not just another nostalgia play from one of cinema’s most recognizable audio brands. Now operating under Razer ownership after the 2016 acquisition, THX is using “Spark” to connect its Lucasfilm-era legacy with the next phase of immersive entertainment, including HDR10+ video and Eclipsa Audio. For a logo that once told audiences the theater was properly calibrated, this is THX trying to make the same argument in a very different format war.
Pro Tip: The first THX Deep Note trailer debuted in 1983.
THX Deep Note “Spark” Updates a Familiar Cinema Ritual
“Spark” blends the nostalgia of THX’s Lucasfilm-era origins with a more modern visual and sonic presentation. The trailer reflects the company’s long-standing mission to help audiences experience movies, music, games, and home theater content closer to the way creators intended.
It also acknowledges THX’s role in raising theatrical presentation standards during the Star Wars era, when George Lucas and Tomlinson Holman pushed for better sound and picture quality in cinemas. More than four decades later, “Spark” gives the Deep Note a fresh identity while preserving the familiar slow build and signature crescendo that made the THX trailer part of the moviegoing experience.
“As entertainment evolves, so does the role THX plays in bringing a creator’s full vision to audiences,” said Tuyen Pham, chief executive officer of THX Ltd. and veteran immersive audio innovator. “This trailer honors our legacy while embracing a future for open technology format standards for broader access for creators and deeper enjoyment by the audience. By releasing the Trailer in HDR10+ and Eclipsa Audio, we are empowering more storytellers, artists, and technologists to build extraordinary experiences that reach fans exactly as intended—faithfully, powerfully, and without compromise, with technology accessible to all via open standards of excellence and fidelity.”
The artistic approach for “Spark” is intended to symbolize imagination taking shape as an audiovisual journey, beginning with a “spark” from THX’s early innovations and media playback standards. It celebrates the creative possibilities of today’s entertainment landscape across concert venues, cinemas, home theaters, gaming rooms, and mobile devices enjoyed with headphones.
“THX was built on the idea that technical rigor and artistic ambition go hand in hand,” said Grace Qaqundah, senior vice president, THX Ltd. “Spark is a tribute to our history and a beacon for what lies ahead. We are thrilled to share it with audiences around the world as a spark of what’s possible when imagination meets high fidelity.”
The Spark also marks the first THX trailer released in the new open standards HDR10+ video and Eclipsa Audio. This is a strategic movie by THX that illustrates their commitment to open standard technology ecosystems that enable broad creator adoption and high-fidelity experiences across theaters, home entertainment, gaming platforms, and certified devices.
Who Supports HDR10+ and Eclipsa Audio?
Samsung has been one of the first major TV brands to support Eclipsa Audio, bringing the format to its 2026 TV and soundbar lineup. HDR10+ also has a much broader device footprint, with more than 22,000 certified products across categories including TVs, computer monitors, projectors, automotive displays, tablets, mobile phones, streaming devices, AVRs, and Blu-ray players. Supporting brands include Samsung, Panasonic, JVC, Xiaomi, TCL, Hisense, and Skyworth.
“Spark” is also expected to appear in THX Certified Cinemas in the second half of 2026, as well as on displays from THX brand partners and THX Certified devices.
The inclusion of both HDR10+ and Eclipsa Audio follows THX’s recent expansion of its audio/video technology laboratories in Asia. The company’s Shenzhen lab has been named an Authorized Test Center for both HDR10+ and Eclipsa Audio certifications for consumer electronics and home theater devices.

The Bottom Line
The THX Deep Note has been part of the cinema experience since 1983, when it debuted ahead of Star Wars: Episode VI — Return of the Jedi. That history matters because THX helped establish the idea that going to the movies should come with a higher standard for sound, picture, and presentation, not just a bigger screen and a sticky floor.
Since then, theater chains and studios have pushed premium formats such as IMAX, Dolby Cinema, ScreenX, RPX, and others, but the THX Deep Note still carries a very specific meaning for moviegoers. It is a signal that the room, the sound system, and the presentation are supposed to matter. “Spark” updates that ritual for today’s immersive cinema landscape while keeping the familiar build that tells audiences the outside world can wait for the next two hours.
THX says “Spark” is expected to debut in THX Certified Cinemas in the second half of 2026, along with appearances on displays from THX brand partners and THX Certified devices.
