CCM663

See nothing, hear everything

The CCM663 is a true high performance ceiling-mount speaker. The tweeter
has a 25mm (1in) aluminium dome and its housing pivots for adjustable off­axis treble response. The bass/midrange driver’s die-cast chassis provides
extra rigidity which results in a cleaner, faster bass, and a three-position EQ
switch for a better off-axis response. The blue Kevlar® cone means that the
unit is well hidden behind the grille but still produces a remarkably clear and
dynamic sound. Incorporating QuickDogs™ and plug-and-play functionality it
is quick and easy to install.
