 | Sound Engineers, long ago, have recognized the importance of
using one Point Source Sound Speaker, in the Classroom, for
Speech. |
 | Many Classrooms, in Alberta, have this type of speaker as part of
their Public Address System. |
 | The use of more than one speaker, in the classroom, for speech
is contrary to what has been proven to be the best long ago. |
|

The Speaker, shown above, is:
 |
a Point Source Sound Speaker. |
 |
a Flush Mounting Speaker. |
 |
a Conventional Speaker.
( It is not a Wide Dispersion Speaker ) |
