Pure Resonance Audio C5 4 Inch 70V Micro Ceiling Speaker

If you want clean audio coverage without big, bulky ceiling hardware, the Pure Resonance Audio C5 is a smart pick. It’s a compact 4 inch micro ceiling speaker designed for commercial environments where you need consistent paging intelligibility and pleasant background or foreground music.

Because the C5 is 70V and 100V compatible, it fits the way most business audio systems are actually built, multiple speakers, longer wire runs, and easy zone planning. The built-in 10W transformer makes it practical for distributed audio layouts in offices, retail stores, restaurants, hospitality spaces, classrooms, conference rooms, reception areas, and waiting rooms. It also works well in systems where you want a subtle, even sound layer for sound masking support.

The real advantage here is the low-profile approach. In many commercial installs, you want the ceiling to look clean and modern, while still getting coverage that feels “everywhere” instead of “right under the speaker.” The C5 is built for exactly that, a discreet ceiling presence that supports consistent audio across the space.

Common use cases include:
Office background music plus paging and announcements
Retail sales floor music with clear callouts when needed
Restaurants and lounges that want even sound without hot spots
Hotels, foyers, and lobbies where aesthetics matter
Classrooms and conference rooms that need voice clarity
