      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)
