CCM663RD
RD stands for Reduced Depth – so this speaker will fit into tighter
spaces than the standard CCM663. A shallower cone and a redesign of
the easy-fit QuickDogs™frame reduce depth to a more usable 92mm,
while retaining everything that makes the CCM663 such a great in-
ceiling speaker.
The familiar, yet discreet, dark blue Aramid Fibrecone of the bass/
midrange driver delivers a stunningly clean, detailed response. This,
combined with the pivoting aluminium dome tweeter for adjustable off-
axis treble response and three-position EQ, make this one of the most
versatile custom speakers around.
If preferred, the supplied round grille can be replaced with an optional,
square CCM663 grille.
