Cosmetically And Mechanically, The Passives Match The Shielded Dvc Line Of Subwoofers, With A Poly Coated Paper Cone And Medium-Roll Rubber Surround For Clean Excursion And Long Life. The Possibilities With These Passives Are Endless, From Floor Standing Two-Ways To Small Active/Passive Subwoofer Systems. Specifications: Fs: 23.3 Hz Vas: 43.1 Liters Qms: 7.34 Cms: 0.68 Mm/N Rms: 1.4 Kg/S Mms: 68.8G Sd: 211.2 Sq. Cm. Xmax: 10 Mm Dimensions: Overall Diameter: 216 Mm, Cutout Diameter: 180 Mm, Depth: 58 Mm. Note: Adding Mass To The Passive Radiator Will Decrease Fs And Increase Qms. Tip: As A General Rule The Passive Radiator(S) Should Be Able To Move Double The Volume Of Air As The Active Woofer(S)/Subwoofer(S) In The System. For Example: A Passive Radiator System For A 8'' Woofer/Subwoofer That Has 9Mm Of X-Max Would Require 2-8'' Passive Radiators With 9Mm Of X-Max. For Single Passive Radiator Systems, It Is Common To Use A Passive That Is Larger Than The Active Woofer(S)/Subwoofer(S).
