The 10½" passive radiator PR270WA01 was designed for high performance compact subwoofer applications. Optimized for working with the active 10½" subwoofer SW270WA01 but will function well with any suitable active subwoofer transducers.
Very rigid air dried paper cone to ensure piston motion at high levels
Rigid steel 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
