Wide Range Speaker

CS-304U

The CS-304 outdoor speaker features stainless steel hardware for all-weather durability. It is designed to offer the high intelligibility of weather-resistant horns combined with the high sound quality of dynamic speakers. The CS-304 employs the rotary switch that facilitates impedance changes. It also employs a constant directivity horn for clear sound output over its horizontal range of 90°operation.

Ensure long-lasting outdoor performance with a rust-resistant stainless steel and resin construction.
Deliver uniform sound coverage across your space through the 90-degree constant directivity horn.
Maintain reliable operation in harsh weather conditions with certified IP65 dust and water protection.
Save time during setup by easily adjusting power levels with the built-in rotary switch.
Meet strict safety and professional standards with the UL 1480 listed design.
Enhance facility safety using fire-retardant materials that meet UL94 V-0 standards.
Enjoy flexible installation options on walls or ceilings with the included stainless steel bracket.
