Evolving Year After Year to Deliver Sound That Reaches Further

In the world of sound systems, horn speakers have long been a trusted solution—renowned for their ability to deliver powerful, focused sound that covers wide areas with remarkable efficiency. From public spaces and houses of worship to industrial zones, horn speakers remain a go-to choice for reliable outdoor sound solutions.

 

As one of the pioneers in this field, TOA Corporation made a historic mark in 1947 by developing its very first horn speaker. This product became a milestone in the evolution of public address systems across Japan and many other countries, including Indonesia. Over time, the name “TOA” has become synonymous with horn speakers themselves—an iconic part of daily life in public sound announcements.

 

Since that early innovation, TOA has continued to advance the design, materials, and technology of its horn speakers to meet the ever-changing challenges of outdoor environments. From classic models used in terminals and schools to paging and emergency systems in stadiums and factories, TOA consistently delivers solutions that evolve with the times.

 

A notable example of this evolution is Z-DH502-AS Straight Horn Speaker—an innovation built with dual 60-watt drivers, offering consistently clear and stable sound even in acoustically demanding environments. With wider sound coverage and a modern, durable design, Z-DH502-AS is an ideal solution for outdoor areas such as: stadiums and open fields, large-scale houses of worship, industrial complexes, public address and emergency evacuation systems.

 

While staying true to the classic horn speaker concept, Z-DH502-AS introduces enhanced performance, simplified installation, and increased durability—ensuring long-term reliability in various challenging environments.

 

In Indonesia, TOA products are marketed by the exclusive agent PT TOA Galva Prima Karya. Customers can purchase them through TOA Indonesia’s authorized dealers or online via e-commerce platforms.
