The Apart CM4 is a small 4" loudspeaker ideal for speech and comfortable background music. The discreet ceiling speaker features a back can that gives constant full, rich sound. The back can also makes the CM4 perfect for strip metal or perforated tile ceilings. 

CM4 can be used with a maximum of 4 speakers in parallel on one 4 ohms amplifier channel. In situations where you want to give more punch to the music, you can use the CM4 in combination with a CMSUB8 ceiling mount subwoofer or SUBLIME cabinet subwoofer.
