In-ceiling speakers for music provide high-quality, unobtrusive audio that evenly distributes sound throughout a room, enhancing the listening experience without compromising on space or aesthetics.

The in-ceiling speaker supports the SIP protocol, including SIP v1 (RFC2543) and SIP v2 (RFC3261), ensuring compatibility with a wide range of VoIP systems. It also supports the TCP Play Protocol for reliable audio streaming. With a powerful 20-watt speaker, it delivers clear and robust sound. Additionally, the speaker supports Power over Ethernet (PoE), allowing it to receive power and data through a single Ethernet cable for easy installation and reduced wiring complexity.
