Aiphone SP-2570N 4W 25V/70V Ceiling Speaker

Route paging announcements and background audio to a ceiling-mounted loudspeaker location on either 25V or 70V constant-voltage speaker wiring. The Aiphone SP-2570N is rated at 4W and includes transformer support for connection to distributed audio amplifier systems using either line voltage. It provides a defined endpoint for audible notifications where wall-mounted communications equipment is not the preferred placement. The ceiling speaker format fits installations that need sound coverage without occupying wall space. It can be considered for entrances, corridors, waiting areas, reception spaces, retail floors, and other indoor locations served by a centralized paging or audio distribution system. Select the amplifier output and speaker circuit arrangement to match the required 25V or 70V line architecture and the speaker's 4W rating. Within Aiphone ceiling-speaker options, this model is distinguished by its dual 25V and 70V transformer compatibility and 4W power rating. Those electrical characteristics matter when standardizing a speaker circuit around an existing constant-voltage amplifier rather than using a direct low-impedance speaker connection. The SP-2570N supplies the ceiling speaker and line-transformer function for that type of distributed audio run.
