Hanging Spherical Sound Projector Audac ASP20/B — 70/100V, Black

The Audac ASP20/B is a hanging spherical sound projector engineered for 70/100V line distributed audio systems. Finished in black, this ceiling-suspended loudspeaker delivers omnidirectional sound coverage suitable for background music, paging and ambient sound in commercial, retail and public environments. Its suspended form factor enables flexible placement where wall- or ceiling-mounted cabinets are impractical, while the line operation simplifies multi-speaker installations and long cable runs.

Advantages

The spherical design provides even sound dispersion in 360 degrees, reducing the need for multiple fixed-direction speakers. Operation on 70/100V lines allows easy integration into existing paging and distributed audio networks and reduces the impact of cable length on signal quality. The black finish and compact hanging profile offer discreet visual integration into modern interiors. The projector is intended for ceiling suspension, offering sound coverage from above and minimizing footprint on walls and floors.

Suitable for

• Background music systems in retail stores and shopping areas
• Paging and voice announcements in airports, stations and public buildings
• Ambient sound in restaurants, hotels and lounges
• Distributed audio in large open-plan commercial spaces

Key specifications

• Operation: 70/100V line-compatible
• Acoustic pattern: omnidirectional (spherical dispersion)
• Mounting: suspended/ceiling-hung installation
• Finish: black
• Intended use: background music, paging and ambient sound reproduction

How to use

Install the speaker using appropriate suspension hardware from a secure ceiling structure, following local building and safety regulations. Connect the unit to a 70/100V amplifier or line transformer with compatible tap settings to match the required power and coverage. Position units to achieve even coverage across the listening area, accounting for ceiling height and room geometry. Adjust amplifier output and any available attenuation to balance volume levels with other speakers in the system.

Usage recommendations

Select transformer tap settings that provide adequate SPL for the space without overdriving the speaker; in multi-speaker systems, calculate total line load to ensure the amplifier’s capacity is not exceeded. For aesthetic integration, route suspension cables and wiring through ceiling voids where possible and maintain recommended clearance from HVAC outlets and lighting fixtures to prevent interference with dispersion and mounting integrity.
