Martin Audio C4.8T 4" Ceiling Mounted Speaker
The C4.8T is an extremely compact, two-way flush mount loudspeaker designed to deliver high performance and high intelligibility in a wide range of applications. The unit consists of a 4" (100mm) bass driver with a UL rated, carbon fibre loaded polypropylene cone and a 0.8" (19mm) dome tweeter mounted side by side on the baffle. This configuration easily outperforms coaxial stalk-mounted tweeter or single driver arrangements in terms of wide dispersion and smooth off-axis frequency response. The exceptionally wide dispersion of the C4.8T makes it particularly suitable for installation in low ceilings where significantly fewer units will be required to cover a particular area.
