Dayton Audio DS215-PR 8 Designer Series Passive Radiator

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: 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).
