Performance two-way in-ceiling speaker with adjustable tweeter
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.
