The acoustic challenge
  • Brand sound must be identical in every store, on every floor.
  • Hard retail surfaces create harsh, uneven coverage.
  • Store teams should never need to touch the system.
The CaesarTechs engineering approach
  • Compact architectural loudspeakers on a tight grid for even, low-level coverage.
  • Zoned scheduling with day-parting pushed from a central platform.
  • Level limits and locked presets at store level.

Delivery program
PHASE 01
Acoustic survey

Site measurement of RT60, noise floor and geometry against the architect's model.

PHASE 02
Coverage modelling

Beam plots per zone with predicted STI and SPL maps issued as a report.

PHASE 03
Design & BOM

Loudspeaker schedule, amplifier count, cabling and containment drawn in CAD.

PHASE 04
Supply & staging

Equipment pre-configured and load-tested in the CaesarTechs facility.

PHASE 05
Installation

Mounting details coordinated with the fit-out contractor and MEP package.

PHASE 06
Commissioning & handover

On-site tuning, as-built documentation, operator training and remote monitoring.

Engineering questions

We model the room in acoustic software and issue beam plots with predicted STI for every zone of the retail 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.
