DESCRIPTION

Optimal Audio delivers refined commercial sound with the UP4O, a compact full-range 4" ceiling speaker featuring an open-back design tailored for professional installed audio environments. Engineered for spaces where background music and clear speech reproduction are essential, this loudspeaker provides consistent, wide-dispersion coverage ideal for retail, hospitality, corporate, and leisure venues.

The open-back configuration eliminates the need for a separate backcan, simplifying installation where adequate ceiling void space is available. This makes the UP4O a time-saving solution for integrators working across large-scale distributed audio projects without compromising acoustic performance.

  • 4" full-range driver delivering articulate, balanced audio reproduction
  • Open-back design for streamlined installation in standard ceiling voids
  • Wide, uniform dispersion ensuring even coverage throughout the listening area
  • Low-profile, paintable grille for seamless integration into any ceiling aesthetic
  • 70V/100V line compatible with built-in transformer and multiple tap settings for flexible system design
  • Quick-fit dog-leg clamp system enabling fast, secure single-person installation
  • Robust build quality engineered for long-term reliability in commercial environments

Whether deployed as part of a distributed background music system or a zoned paging network, the UP4O offers installers a dependable, great-sounding solution that balances performance, aesthetics, and ease of deployment in any professional audio installation.
