The acoustic challenge
  • Glass atria and double-height lobbies are acoustically hostile and visually unforgiving.
  • Hybrid meetings demand consistent gain-before-feedback with open microphones on the table.
  • Facilities teams need one control layer across dozens of rooms rather than per-room islands.
The CaesarTechs engineering approach
  • Discreet installation loudspeakers for meeting rooms, steered columns where ceiling heights grow.
  • Beams aimed away from open microphones to protect gain-before-feedback.
  • One networked DSP core with presets per room configuration and remote fault reporting.

Engineering questions

We model the room in acoustic software and issue beam plots with predicted STI for every zone of the corporate space before a single bracket is ordered.

Yes. Beams are steered digitally, so re-tuning after a fit-out change is a software session — no ladders, no re-rigging.

Slim column profiles in custom finishes, flush or recessed where the architecture allows. Most clients see nothing at first glance.

The DSP core supports prioritised emergency broadcast paths and supervised monitoring alongside the everyday program audio.

CaesarTechs provides remote monitoring, firmware management and an SLA-backed response with local engineers.
