Dayton Audio – SD215-PR 8″ Passive Radiator

Dayton Audio – SD215-PR 8″ Passive Radiator

Overview:

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 Hz • Vas: 1.40 cu. ft. • Qms: 2 • Cms: 0.75 mm/N • Mms: 75 g • Sd: 194 sq. cm. • Xmax: 9 mm • Dimensions: Overall diameter: 8.50″, Cutout diameter: 7.09″, 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).
