CCM 618

See nothing, hear everything

CCM 618 is a 2-way ceiling speaker featuring a 200mm (8 in) woven glass fibre

cone bass/midrange driver and an offset, adjustable tilt Ultra-12 tweeter in a chassis

incorporating simple and effective swing-out dog fixings. The larger bass/midrange

driver of the CCM 618 provides improved low frequency performance and increased

sound level capability. The tilting tweeter and three-way EQ switch of the CCM 618

offer directional adjustment and high frequency tonal options allowing the sound to

be more tailored to the installation.
