CCM 663RD In Ceiling Speaker (Pair)

CCM663RD is a high-performance 6-inch in-ceiling speaker with a difference. The ‘RD’ in the name stands for Reduced Depth, and this incredibly shallow speaker is perfect when you need to deliver great sound from a tight space.

A shallower cone and a redesign of the easy-fit QuickDogs™ frame reduce this speaker’s depth to a very slim 92mm, while retaining everything that makes the CCM663 such a great in-ceiling speaker.

The dark Kevlar® cone of the bass/mid driver delivers a clean, detailed response, and combines with the pivoting aluminium tweeter for adjustable off-axis treble and three-position EQ, to make an incredibly versatile custom speaker.

If preferred, the supplied round grille can be replaced with an optional square CCM663 grille.
