Dayton Audio DS90-PR 3" Designer Series Passive Radiator

The Dayton Audio Designer Series 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, these passives match Dayton Audio's Designer Series drives, 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 portable battery powered speaker systems.

Specifications: • Fs: 42.4 Hz • Vas: 0.124 cu. ft. • Qms: 5.9 • Cms: 2.55 mm/N • Rms: 0.3 kg/s • Mms: 5.5 g • Sd: 31.2 sq. cm. • Xmax: 4 mm • Dimensions: Overall diameter: 3.63", Cutout diameter: 2.76", Depth: 0.86".

Note: Adding mass to the passive radiator will decrease Fs and increase Qms.

Tip: As a general rule, the passive radiator(s) should have at least double the displacement of air (Vd) as the active woofer(s)/subwoofer(s) in the system.
To calculate Vd: Sd x Xmax = Vd
