Passive Radiators are another option to the port tube for tuning. They enable a tuning frequency lower than a port by adding mass to the diaphragm. All passive radiators from Pro-Driva enable mass to be added. They also improve power handling by limiting excursion of the active driver, while the passive provides maximum excursion. In general a passive radiator should be twice the diaphragm area of the woofer. However modern passive radiators often these day have twice the excursion of the woofer enabling you to use the same size as the driver.
