The QSC AD-C4T-LP is the low-profile version of the AcousticDesign 4.5-inch two-way in-ceiling loudspeaker, engineered for shallow plenum spaces where mounting depth is limited. At roughly 100 mm deep it fits tight ceilings while still delivering the wide, even DMT (Directivity Matched Transition) coverage and clear sound of the AD-C series. An integrated 70/100V transformer with 16-ohm bypass supports flexible distributed or low-impedance systems. It ships in a paintable white finish.
