X2 enables immersive storytelling with localizing sound

X2 brings immersive storytelling through localized audio

Encounters at the National WWI Museum and Memorial is an immersive, LED-driven installation presenting personal, historical accounts of the The Great War through narrative-focused zones. The HOLOPLOT X2 system delivers highly localized audio to each exhibit area, enabling clear, isolated storytelling within a dense, multi-zone exhibition environment.

A walk through immersive exhibit
With LED alcoves

Encounters is set within a gallery environment defined by closely spaced, LED-driven exhibit zones and an open visitor circulation path. 

Each storytelling area is visually immersive yet physically adjacent, with minimal architectural separation between zones. This dense spatial layout creates a challenging acoustic environment, requiring sound to remain tightly contained to preserve narrative clarity and avoid interference between neighboring exhibits.

"The audio system (provided by HOLOPLOT) allows you to steer audio in a very directional way… and when you are outside of that bubble you can barely hear the audio program. When you step into the bubble, this full fidelity soundtrack is present to you..”
Chris Conte, Electrosonic

The system design
Targeted beam design for coverage zones

The system design at a glance:

  • Four 1x2 X2 Matrix Arrays mounted above LED alcoves
  • Eight X2 Audio Modules utilize PoE++ allowing for just 2 runs of cable to each Matrix Array
  • Single, precisely optimized coverage beam per array, targeting only the listener area directly in front of each exhibit
  • Frequency response tailored for spoken-word character performances, delivering natural sound while remaining tightly controlled to avoid disruption of neighboring zones
  • Additional background music and sound effects programmed to provide gentle sound masking across the exhibit space

Isolated Storytelling
In a shared acoustic environment

Mounted above the LED screens for a fully concealed integration, the system is precisely oriented to maximize acoustic isolation between exhibit zones. This placement keeps the audio experience seamless and unobtrusive, letting the visual storytelling take center stage while sound is delivered exactly where it's needed.

At the technical core, coverage beams are precisely optimized to prevent sound spill into neighboring exhibit areas, while full-range frequency response exceeds the capabilities of conventional "sound-spotlight" solutions. The result is clear, immersive storytelling with strong acoustic separation between adjacent exhibit zones, allowing each installation to tell its own story without interference from the next.

HOLOPLOT x Electrosonic
A collaboration built on trust and expertise

The collaboration between Electrosonic and HOLOPLOT reflects a strong, trusted partnership built on shared standards of excellence. 

Electrosonic, an award-winning international audiovisual and technology services company behind numerous high-profile commercial and entertainment projects, brought deep expertise in narrative-driven environments and complex exhibition spaces, and recognized the value of integrating HOLOPLOT’s technology to meet the exhibit’s acoustic and storytelling requirements.

As described by Electrosonic, the HOLOPLOT system incorporates directional audio beams that create localized “sound bubbles,” immersing visitors in each story while preserving separation between exhibit zones.
