Specifications: • Fs: 34.5 Hz • Vas: 0.046 ft³ (1.32 liters) • Qms: 3.86 • Cms: 1.77 mm/N • Mms: 12.0 g • Rms: 1.49 kg/s • Sd: 22.9 cm² • Xmech: 7 mm • Dimensions: Overall diameter: 2.75" x 2.75", Cutout diameter: 2.52", Depth: 1.73". 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
