    Wavecor Speaker Driver - PR223BD02 8¾" Die Cast Alu Cone Passive Radiator

    Description
    The 8¾" passive radiator PR223BD02 was designed for high performance compact subwoofer applications. Optimized for working with the active 8¾" subwoofers SW223BD02 and SW223BD03 but will function well with any suitable active subwoofer transducers.

     

    Features

    • Very rigid black aluminium cone to ensure piston motion at high levels
    • Rigid die cast alu chassis with extensive venting for lower air flow speed reducing audible distortion
    • Low-loss suspension (high Qm) for better reproduction of details and dynamics
    • Conex spider for better durability under extreme conditions
    • Custom tunable by adding one or more of the three extra weights (included)
