Dayton Audio\'s DMA90-PR 3-1/2 aluminum cone passive Radiator allows you to tune small enclosures lower than possible using conventional ports.
Tip: As a general rule, the passive radiator(s) should have at least double the displacement of air (Vd) as the active woofer(s)/subwoofer(s) in the system.
To calculate Vd: Sd x Xmax = Vd.
