DESCRIPTION
TOA's CS-154 and CS-304 speakers are for outdoor-use, they use
wide-range horns that can provide background music or paging
announcements which have high quality sound. They are designed to
produce high output with an increase of the speaker acoustic
conversion efficiency, by the use of a horn in combination with a cone
speaker. The CS-154 and CS-304 use constant directivity horns (90°
horizontal) to control sound directivity, realizing uniform and clear
sound dispersion over a wide area. These wide-range speakers are
also designed to stand up to the rigorous weather conditions when
installed outdoors.* The speakers' ABS resin enclosure is light in
weight, structurally strong and resistant to impacts. Since the
enclosures are also treated with weatherproof polyurethane resin
paint, they are extremely resistant to the effects of ultraviolet light. The
speakers also comply with IP65 Standard requirements for dust proof
and waterproof capabilities. In addition, the internal speaker parts
feature a special weatherproof treatment to enhance the waterproof
properties of the entire speaker. Stainless-steel brackets and screws
further protect the unit from rust and corrosion. Speaker impedance
can be easily changed externally with a rotary switch, facilitating
changes in impedance during and after speaker installation.

FEATURES
• Wide-range paging speaker for voice paging, background music and tone signaling distribution.
• Constant directivity horn improves directivity characteristics and ensure uniform and clear sound dispersion.
• High sensitivity: up to 98 dB (1W/1m)
• Weatherproof polyurethane resin paint permits the speaker to withstand demanding environmental conditions.*
• IP65 standard compliant.
• Lightweight ABS resin enclosure that is mechanically strong and resistant to impact.
• Stainless steel hardware protects the speaker from corrosion.
• Stainless steel mounting bracket for easy installation and aiming in wall, pole or ceiling-mount applications.
• Ideal for schools, parking facilities, boats, industrial, parks, swimming pools, and so on.
* Do not install the speaker face-up from a horizontal plane nor in such a way that the paper cone is exposed to direct sunlight.
If water accumulates on the paper cone, or ultraviolet rays are radiated on it, this may cause the paper cone to deteriorate, leading to speaker malfunction.
