Accuton P220. 8 inch passive radiator with aluminium dome.
The P220 is an 8 inch passive radiator with aluminium dome. Extra mass can easily be added to tune the resonance frequency. A simple screw mount provides fixing of stainless steel discs 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:
Fres= sqrt[1/(Cms corr.) x Mms x 4 pi^2)] with Cms corr.= 1/[(1/Cms) + 1/((Vb/Vas) x Cms)]
