The Dayton Audio Passive Radiators are excellent general-purpose passives suitable for replacement or for new construction. A built-in mass disc offers a good starting point for most designs, and a convenient M5 threaded hole (screw included) allows different types of weights to be added if desired. 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.
• Fs : 17 Hz
• Vas : 5.20 cu. ft.
• Qms : 3.00
• Cms : 0.45 mm/N
• Mms : 200 g
• Rms : 7.03 kg/s
• Sd : 480 sq. cm.
• Xmax : 10 mm
• Dimensions: Overall diameter: 12.36", Cutout diameter: 10.71", Depth: 3.50".
Adding mass to the passive radiator will decrease Fs and increase Qms.
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 12" woofer/subwoofer that has 10mm of X-max would require 2-12" passive radiators with 10mm 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).
