The CM4 is a small 4” low impedance ceiling mount
speaker. It is so stylish and discrete that it fits into any
interior style or decoration, private or public. This speaker
is small but offers good musical and speech quality.

The acoustical metal back can improves the sound
response and protects against falling debris. This design
makes CM4 speaker ideal for use in strip metal or
perforated tile ceilings. Those ceilings allow the air that
displaced by the loudspeaker cone to escape, resulting in
a sound that lacks ‘body’. The back can of CM4 prevents
this and guarantees a full, rich sound. Thanks to the
strong spring clamps, the CM4 can be used in very thin
ceiling material.

It has only 100 mm mounting depth, which guarantees it
can be used in a wide variety of applications.

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.

The redesigned CM4 ceiling mount speaker now comes with
an elegant and stylish Apart removable logo.

The CM4 loudspeakers can be painted in any colour.
