The CCM664 is a ceiling speaker distinguished by its adjustable tilt offset 25mm (1in) soft dome tweeter. It brings both a smoother and more detailed high frequency performance to a package that also includes a woven glass fibre150mm (6in) bass/midrange driver and three-position EQ switch for a better off-axis response. CCM664 is a classically simple and cost effective route to high quality ceiling mount sound and is simple and quick to install. See nothing, hear everything
