The APart CM20T 2-way built-in loudspeaker can be used as a 16 Ohm or 100 Volt loudspeaker. In 16 Ohm use, you can connect up to 4 loudspeakers in parallel on each channel of a standard 4 Ohm amplifier. For 100 use, the CM20T is equipped with a highquality 20 Watt 100 Volt transformer with several power tappings. Therefore it can be used with high ceilings or places where more back ground noise is present. The loudspeaker has a 6 ½” enforced Polypropylen woofer what results in a very low distortion. To complete the sound a 1″ tweeter has been integrated. It makes the CM20T very suitable for the distribution of microphone calls and back ground music. The housing is made of high quality ABS. The woofer is made out of enforced polypropylen, what makes it moistureproof. The standard colour is white. From 12 pieces on, the loudspeakers can be painted optionally in any other RAL colour

Cutout Ø : 183 MM Remove the grill before mounting. You can see four Philips head screws. Use these screws to thigthen the dog-ears.
