Product information "Accuton P280"
The P280 is an 11 inch passive radiator with sandwich dome. Extra mass can easily be added on a robust mounting body to tune the resonance frequency. 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 calculatd 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)]
- resonance frequency fs = 21 Hz
- effective piston radiating area Sd = 408 cm2
- effective mechanical mass incl. air load mms = 63 g
- equivalent volume of compliance Vas = 226 l
- mounting diameter d = 251,2 mm
- overall diameter d = 280 mm
- mounting depth (not countersunk) t = 131,95 mm
