TOA / CM-1830A Ceiling Speaker

The TOA CM-1830A is a ceiling-mounted speaker. You can choose the speaker panel (sold separately) that best suits your installation environment. The spring-catch system allows for easy installation by simply hooking the panel. The plug-in connector allows for one-touch wiring, and relay terminals are included as standard, reducing the amount of construction required when using a three-wire system with an attenuator (sold separately).
