Horn-Array Series

Horn Array Speakers for long distances. Loud for miles, soft beside.


Experience exceptional sound precision with TOA’s Long Range Horn Array Speaker Series, engineered to deliver clear, intelligible audio over long distances while minimizing vertical sound dispersion and reducing nearby noise interference. Designed specifically for outdoor mass notification, these speakers excel in providing reliable announcements, emergency broadcasts, and warning signals in critical situations, making them an essential choice for any large-scale communication need. 


Key Features: 

  • Focused sound delivery: The innovative array configuration provides a wide horizontal dispersion angle up to 90°. Thus, directing the sound to a precisely defined area. This design minimizes noise spillover, ensuring that messages are heard clearly without disturbing nearby areas, making it ideal for settings where noise control is essential. 
  • Extended sound range:  Thanks to its innovative design, the speaker’s series provide coverage far beyond conventional models. Practical tests conducted at an airfield near Hamburg, Germany and in the desert near Dubai demonstrated the speaker's ability to transmit clear, intelligible messages over distances of more than 1 km. 
  • Reduced installation costs: Thanks to the superior sound coverage of the Horn Array Speakers, fewer units are needed to achieve optimal coverage. This not only reduces installation costs but also helps to avoid the common issue of overlapping sound, which can cause confusion and diminish the intelligibility of announcements. 
  • Versatile applications: Originally developed for disaster prevention, these EN-54-24 certified speakers can be easily integrated into existing voice alarm systems. Furthermore, their dedicated design for long distance transmission makes them suitable for a variety of environments, including: 

-Industrial Sites: Cover large areas with just a few speakers, enabling cost-effective communication in high-security zones. 

-Mosques: Reach worshippers from afar while minimizing noise disturbance to nearby residents. 

-Parks, Ski Resorts, and Amusement Parks: Ensure clear announcements over long distances, enhancing the visitor experience and safety. 

  • Durable and weatherproof: Available in four sizes, each speaker features a robust, weatherproof design with a saltwater-resistant coating. This ensures durability and reliability in various outdoor conditions, making them suitable for installations near coastal areas or in harsh environments. Their condensed design also reduces the wind catchment of the speakers minimizing the wind force applied to the mounting structures. 
  • Energy-efficient design: Designed with energy efficiency in mind, these speakers minimize power consumption without compromising performance, making them an environmentally friendly choice for mass notification.


Backed by TOA’s decades of expertise in mass notification solutions, including our outstanding role as Japan’s leading provider of disaster prevention speakers, this series builds on over 15 years of pioneering development to ensure reliable performance in the most critical situations.
