The CCM663 is a true high performance ceiling-mount speaker. The tweeter
has a 25mm (1in) aluminium dome and its housing pivots for adjustable off-
axis 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 blueAramid Fibrecone means
that the unit is well hidden behind the grille but still produces a remarkably
clear and dynamic sound. Incorporating QuickDogsand plug-and-play
functionality it is quick and easy to install.
