15 W VoIP horn loudspeaker

The Bogen SPT15A is a 15 watt horn loudspeaker with a built-in transformer for voice-over-IP paging systems. It connects to a PoE network port and converts digital audio streams into amplified analogue output for indoor or outdoor announcements.

Transformer-coupled 15 W output

The integrated transformer matches the amplifier to the horn driver at 15 watts, so the speaker produces the rated output without an external matching unit. Installations that require a different power tap or a line-level input cannot use this model.

Questions about this item

How loud is the 15 watt output in a typical installation?

The 15 watt rating provides sufficient volume for paging and announcements in medium-sized indoor or outdoor areas such as warehouses, parking lots, or school corridors.

What network standard does the VoIP interface use and what does it limit?

The VoIP interface connects via standard Ethernet and is limited by the available network bandwidth and PoE power budget for the 15 watt amplifier.
