Bowers & Wilkins CCM663 Ceiling Speakers Pair With the CCM663 it gives high performance ceiling mount speakers. The Tweeter has a 25 mm aluminium dome and its housing pivots for an adjustable off-axis treble response. The Bass/Midrange driver’s die cast chassis provides extra rigidity which results in cleaner, faster bass and three position EQ switch for a better off-axis response. The Blue Aramid Fibre cone means that the unit is well hidden behind the grille but still produces remarkably clear and dynamic sound.
