TOA
H-3 Wall Mount Speaker
has a wide 140 degree horizontal coverage pattern and
its Minimum Reflection design significantly reduces sound wave
reflections and the resulting sound coloration that occurs
with
conventional bracket-mounted “box” type speakers. |
|
 |
TOA
F-121C Ceiling Mount Speaker
is significantly better than Conventional Speakers in its ability to
disperse the High Frequencies throughout the Classroom and provide
an extremely Wide Quality Sound Coverage. The F121C Speaker is your
best choice for large classrooms with its Dedicated Equalization
Module, which delivers Superb
Sound Quality that has become the standard for University
Classrooms. |

Dispersion Pattern
Wide Dispersion Speakers versus Normal Speakers, in a 65' x 65' Room. |
Uniform - Dispersion & Coverage
The picture above shows how well the TOA F-121C Speaker uniformly
disperses the High Frequency Sound as compared to Standard Ceiling
Speakers.
Also, this picture shows four speakers being used in a 65' x 65'
Room
however, only One F-121C Speaker is required in a 32' x 32' Classroom.
The wide dispersion characteristics of the TOA F-121C Speaker provide a
Uniform Sound Level, throughout the Classroom, for all the Students. |
Dispersion Characteristics
 | Standard Speakers - Direct Sound Projection
- Speaker Cone Sound projected directly into the Classroom. |
| Wide Dispersion Speakers - Indirect Sound Projection
- Speaker Cone Sound projected via a Sound Diffuser
into the Classroom. |
| F-121C Speaker - Diffuser
 | Ball Type of Diffuser Built-In Speaker Grill |
| Diffuses Both, the Bass and the Treble. |
|
| H-3 Speaker - Diffuser
| Treble is projected upward into a Plastic Diffuser. |
| Diffuses the Treble Only. |

Wide Dispersion Speakers -
Minimize the Potential for
Feedback
|
| Wide
Dispersion Speakers disperse the high frequencies throughout the classroom
and deliver a more uniform audio level throughout the classroom thereby
minimizing the potential for feedback as the teacher walks under the
Ceiling Speaker or in front of Wall Mount Speaker. Standard Speakers have
a high frequency hot spot, directly in front of them, and are more prone
to cause feedback. |
