OXS S5 Soundbar: Bring the Cinematic Dolby Atmos Experience Home

Update on July 24, 2025, 5:54 a.m.

Close your eyes. Picture the scene. The heavy, thudding footsteps that shake a glass of water on a dashboard. The tense whisper that seems to materialize directly behind your shoulder. The sudden, deafening roar of a starship jumping to hyperspace, its sound seeming to tear through the very fabric of your room. Sound, when masterfully wielded, is more than just an accompaniment to visuals; it is a primary author of emotion, a sculptor of space, and the most powerful tool for immersion in a storyteller’s arsenal.

For nearly a century, a quiet and relentless quest has been underway: the pursuit of capturing and recreating sound so realistic it could dissolve the walls of our living rooms and transport us directly into the heart of the action. This is not merely a story of more speakers or louder volumes. It is a fascinating journey through physics, human psychology, and audacious engineering. It’s a journey that began with a simple, revolutionary patent in 1931 and leads directly to the sophisticated audio technologies of today, like Dolby Atmos, which are now more accessible than ever in devices like the OXS S5 Soundbar. This is the story of how we learned to paint with sound.

The Birth of a Canvas: Inventing the Soundstage

For the first few decades of recorded audio, the world was sonically flat. Sound emanated from a single point, a mono source, lacking any sense of width or depth. The revolution began not in a grand concert hall, but in the mind of a brilliant British engineer named Alan Blumlein. While watching an early “talkie” film in 1931, he was struck by the absurdity of actors on one side of the screen having their voices project from a speaker on the other. His solution, outlined in a patent of breathtaking foresight, was what we now know as stereophonic sound.

Blumlein’s genius was rooted in a fundamental understanding of psychoacoustics—the science of how our brain interprets sound. He knew that we perceive the direction of a sound source using two primary cues. The first is the Interaural Time Difference (ITD): a sound from our right will reach our right ear fractions of a millisecond before it reaches our left. The second is the Interaural Level Difference (ILD): that same sound will be slightly louder in our right ear. By recording with two microphones and playing back through two speakers, Blumlein realized he could trick the brain. He could create a virtual “soundstage,” an auditory canvas stretching between the two speakers upon which engineers could place instruments, voices, and effects, giving music and film a newfound sense of space and realism.

Chasing the Ghost: The Awkward Adolescence of Surround Sound

Once the horizontal canvas was established, the next logical frontier was to surround the listener completely. This chase for full immersion had a few notable, if clumsy, early steps. Walt Disney’s “Fantasound” system for the 1940 film Fantasia was a pioneering, complex multi-channel setup, but it was far too unwieldy for widespread adoption. The 1970s saw a commercial push for “Quadraphonic sound,” which used four speakers. It was an ambitious idea that ultimately collapsed under the weight of competing, incompatible formats and high costs, leaving consumers confused and wary.

The true breakthrough came, once again, from the cinema. Ray Dolby’s Dolby Laboratories, founded in 1965, had already revolutionized audio with its noise-reduction technologies. In 1976, it introduced Dolby Stereo, a system that cleverly encoded four channels of audio (left, center, right, and a single surround channel) onto the same two optical tracks used for stereo. Films like Star Wars and Close Encounters of the Third Kind used this technology to create immersive soundscapes that were, for many, as awe-inspiring as their visual effects. This established the “channel-based” paradigm that would dominate audio for the next three decades, evolving into the familiar 5.1 and 7.1 digital surround sound formats of the home theater boom. The philosophy was simple: you had a fixed number of speaker channels, and you directed sounds to them.

The Digital Brain and the New Dimension

For all its success, channel-based audio had a limitation. A sound was either in one channel or panned between two. It couldn’t exist as an independent entity in the space between or above the speakers. The next great leap required not just more channels, but a revolution in processing power, delivered by the unsung hero of modern electronics: the Digital Signal Processor (DSP). These powerful, specialized microchips are the brains that allow a device to perform billions of complex mathematical calculations per second, decoding intricate audio signals and rendering them in real-time.

With the advent of powerful DSPs, a new philosophy became possible: object-based audio. This is the core innovation of Dolby Atmos. Instead of mixing sound to a fixed number of channels, sound designers can now treat an individual sound—a buzzing bee, a ricocheting bullet, a line of dialogue—as a discrete “object.” They can place this object anywhere in a three-dimensional virtual space and define its movement.

When you play Atmos content on a capable system, its DSP reads this positional data and uses all available speakers to precisely render the object in your room. This is where a modern soundbar like the OXS S5 showcases the culmination of this history. Its 3.1.2 architecture is a purpose-built engine for this new audio world. The front-firing ‘3’ channels anchor the primary action and dialogue with clarity. The built-in ‘.1’ subwoofer provides the low-frequency foundation, with a response down to a tactile 55Hz.

But the magic lies in the ‘.2’—the two upward-firing speakers. They fire sound at your ceiling, using the simple law of acoustic reflection to bounce it back down to you. This is a brilliant psychoacoustic trick. Your brain, detecting sound arriving from above, creates a convincing illusion of height. It completes the sound dome, allowing the buzzing bee to hover over your head and the rain to fall from a virtual sky. The system isn’t just making sound; it’s actively manipulating physics and your perception to build a world.

To feed this sophisticated audio engine, you need a data pipeline wide enough to carry the massive, uncompressed audio streams. This is the crucial role of HDMI eARC (Enhanced Audio Return Channel). It is the data superhighway that ensures every bit of the complex, object-based audio information reaches the soundbar’s DSP without being compressed or compromised, preserving the integrity of the original mix.

The Democratization of Immersion

From Alan Blumlein’s sketch pad to the digital rendering engines of today, the quest for immersive sound has been a breathtaking marathon of innovation. What once required custom-built cinema installations or complex, multi-component home systems can now be realized in a single, sleek device. The OXS S5 is a microcosm of this journey, integrating the principles of stereophonic imaging, surround sound envelopment, and object-based height into one accessible package.

It stands as proof that technology, at its best, serves art. It empowers creators to tell their stories more profoundly and allows us to experience them more deeply. The next time you watch a film and a subtle sound effect makes you instinctively glance over your shoulder, take a moment to appreciate it. That fleeting, visceral reaction is the product of nearly a hundred years of scientific curiosity and artistic ambition, finally delivered right to your living room.
