Loa hộp 6W TOA BS-680FC
-Constructed with metal cabinet, the speaker is ideal for use in a voice alarm system.Can be surface- or flush- mounted to the wall.
-Either concealed in-wall wiring or exposedwiring can be used for speaker cable connection.
-The speaker structure of direct wall-mountingwith screws prevents the speaker from falling easily even if an outward force is applied to.The input impedance can be easily changed by changing the tap position of the transformer.
-The built-in 16 cm double cone speaker unit delivers high quality sound. Two steatite screw terminal blocks (1 cable to 1 connection type) make bridge connection easier.
