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.

Specifications: • Fs: 21.9 Hz • Vas: 105.8 liters • Qms: 3.98 • Cms: 0.6 mm/N • Mms: 88.4g • Rms: 3.1 kg/s • Sd: 353 sq. cm. • Xmax: 11 mm • Dimensions: Overall diameter: 270 mm, Cutout diameter: 227 mm, Depth: 71.4 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 10" woofer/subwoofer that has 10mm of X-max would require 2-10" 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).
