The 7" passive radiator PR182BD02 was designed for high performance compact subwoofer applications. Optimized for working with the active 7" subwoofers SW182BD03 and SW182BD04 but will function well with any suitable active subwoofer transducers.
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)
