The Commercial CM20T loudspeaker is a two-way built-in, ceiling mount that can be used as a 16 ohms or 100 volt loudspeaker. In 16 ohms use, you can connect up to 4 loudspeakers in parallel on each channel of a standard 4 ohms amplifier. For 100 volt use, the CM20T is equipped with a high-quality 20 watts 100 volt transformer with several power tappings (20 – 10 – 5 – 2.5 watts). Therefore it can be used in projects with high ceilings or places with background noise where a little more power is needed.
The loudspeaker has a 6.5-inch enforced polypropylene woofer that results in very low distortion. To complete the sound, a 1-inch tweeter has been integrated. It makes the CM20T very suitable for the distribution of microphone calls and background music.
The housing is made of high-quality ABS. The woofer is made from enforced polypropylene, what makes it moisture-proof. The aluminum grill makes CM20T humidity proof and ideal to be used in bathrooms, kitchens, etc. The loudspeaker is easy to install due to its simple, quick-mounting system with only 3 screws. These screws are hidden behind the loudspeaker grill.
This loudspeaker is now updated with a new Quick Fix connector and transformer tapping sticker for an even faster and easier installation.
Versatile for almost every market around the globe due to the addition of the 70/100V connection, the CM series is bound to stay the standard installer’s choice in the fixed install market.
The CM20T loudspeakers can be painted in any color.
