The P173 is a high-tech 6.5" passive radiator with aluminum dome. Extra mass can easily be added to tune the resonance frequency. A simple screw mount provides fixing of stainless steel discs (not included) in the desired quantity. The values of Vas and Cms allow for extensive tuning and various box sizes. The stated resonance frequency of the passive radiator is taken at 3mm excursion to give a realistic value. It can be calculated by the following equations:
