In-wall Speakers

Installing the speaker inside a wall is unobtrusive and deters theft. However, installation can be
costly and proper aiming and positioning are often problematic. The TOA H-1 in-wall speaker
overcomes this obstacle by using rotating speaker elements to aim sound where it is needed.
Proper spacing is important, especially for speech intelligibility.

Paging Horns

Paging horns can achieve a higher SPL than ceiling or wall speakers, but have limited frequency
response, lower sound quality, and higher distortion levels. They are seldom used for music ap-
plications but are commonly used outdoors where long sound projection distances are needed.
They are also used in noisy environments where high sound levels are required for intelligible
messages (i.e., large public spaces, warehouses, and factories). When properly aimed and in-
stalled, their controlled coverage and reduced low frequency output increases the direct sound
level and reduces low-frequency masking, which are significant advantages in large rooms. The
TOA SC Series wide-range paging horns offer a compromise between high output levels and
sound quality that is preferred for outdoor music applications.
