P280
Passive radiator


The P280 is an 11 inch passive radiator with 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. A new basket design provides for perfect airflow without compression effects or turbulences. Please note, that the resulting resonance frequency is NOT a constant with all spiders used today. This is why we use graph areas in the diagramm. It depends on the excursion of the dome, because all spiders have a progressive characteristic. The Cms value rises by a factor of approximately 2 at 6mm excursion. Therefor, the excursion should be kept low by applying enough piston area. The stated resonance frequency of the passive radiator is taken at 3mm excursion, offering a realistic value.
