H-3 Wide Dispersion Speaker






THE H-3 WIDE-DISPERSION WALL-MOUNT SPEAKER is the newest addition to the TOA Interior Design Series and continues TOA's modern, innovative approach to commercial speaker design. The H-3's unique appearance and superb sound quality provide a welcome alternative to the use of conventional speakers in Classroom Applications.

The H-3 is a two-way, sealed enclosure with high quality components including a 1 dome tweeter, dual 4" woofers, matching transformer, and removable terminal block. 



Wide Coverage Area
The H-3's wide 140 degree horizontal coverage pattern provides a solution for eliminating dead spots inherent between conventional wall-mounted speakers.

Conventional Speakers disperse sound like Flash Lights.


Wide Dispersion Speakers disperse sound like Light Bulbs.


H-3 Speakers provide 140 horizontal x 70 vertical dispersion.


Point Source Sound
The H-3 with its wide dispersion pattern makes it possible to use only one H-3 Speaker in the Classroom (to have a Single Point Sound Source) which is the best for listening to Speech, from a Clarity and Intelligibility Perspective.


Sound & Amplified Sound emanate from the Same Direction
Using the H-3 Speaker, the Sound Source (the Teacher's Voice) and the Amplified Voice emanate from the same direction (the front of the classroom) to deliver the best Audio Clarity & Intelligibility to the Students.


Flush - Wall Mounting Speaker - Minimum Reflection Design
The H-3 is a Flush - Wall Mounting Speaker which significantly reduces sound wave reflections and the resulting sound coloration that occurs with conventional bracket-mounted "box" type speakers which do not mount flush with the surface of the wall.
