CP-WT380IDC is incorporating Monitor Audio’s innovative, pivoting inverted dual concentric mid range/tweeter module and 8" RST C-CAM bass driver, the three-way CP-WT380IDC represents the highest level of new CP performance. Our innovative Tri-Grip fixing system is easier to install than conventional clamping schemes but provides three times the surface area and a better surface seal, maximizing bass response and mid-range clarity.
