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.
Nominal Diameter :8"
Fs : 23.3 Hz
Vas : 1.52 cu. ft.
Qms : 7.34
Cms : 0.68 mm/N
Rms : 1.4 kg/s
Mms : 68.8 g
Sd : 211.2 sq. cm.
Xmax : 11 mm
Dimensions: Overall diameter : 8.50", Cutout diameter: 7.125", Depth: 2.28".
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).
