Back to Overview
The P173 ist a 6,5 inch Passive Radiator with an Aluminium Sandwich Dome. Extra mass can easily be added to tune the resonance frequency. A simple but robust 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, offering a realistic value.
It can be calculated as follows:
Fres= sqrt[1/(Cms corr.) x Mms x 4 pi^2)] with Cms corr.= 1/[(1/Cms) + 1/((Vb/Vas) x Cms)]
