TOA / CM-2330A Ceiling Speaker

The TOA CM-2330A is a ceiling-mounted speaker that allows you to select 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).
