When every word counts in noisy, outdoor, or high-ceiling industrial spaces, the Algo 8507 IP Horn Array Speaker steps up. This rugged 7-horn array delivers powerful, clear wideband audio up to an impressive 137 dB—think jet-engine volume—while its narrow vertical and wide horizontal dispersion pattern keeps sound focused exactly where you need it. Built for real-world punishment with IPX9 weatherproofing and extreme temperature tolerance, it’s the go-to solution for airports, warehouses, manufacturing plants, and distribution centers that demand reliable paging and emergency alerts.
The Telecom Spot Expert Take: IT teams and facility managers love the Algo 8507 because it replaces finicky analog horns with modern SIP flexibility and crystal-clear wideband audio that actually gets heard. In loud, echo-filled environments, the directional pattern cuts reflections and feedback while the 170 W output ensures coverage across huge areas. Whether you’re paging shift changes, broadcasting safety alerts, or integrating with your existing VoIP system, this speaker scales easily and installs cleanly—saving time and headaches for busy tech teams.

This IP horn array speaker, the 8507, utilizes seven high-powered horn speakers to deliver exceptional audio coverage in outdoor or expansive environments. Its wideband technology ensures high intelligibility and paging clarity for voice announcements and emergency notifications at volumes up to 137 dB. For maximum coverage, place in outward-facing clusters around a central location such as a pole, providing 360-degree loud audio.
The 8507 is a fully compliant third-party SIP endpoint that can work with majority of UCaaS and mass notification platforms. Being a multicast device, it can be seamlessly integrated into existing systems and easily managed by device management platforms like ADMP.
