CCM 636

See nothing, hear everything

The CCM 636 is a ceiling speaker distinguished by its adjustable tilt offset 25mm (1 in) soft dome tweeter. It brings both smoother and more detailed high frequency performance to a package that also includes a woven glass fibre 165mm (6½ in) bass/midrange driver and three-positionswitchable high frequency equalisation. Installation simplicity is catered for by a simple and effective integrated swing out dog fixing chassis. CCM 636 is a classically simple and cost effective route to high quality ceiling mount sound.
