Dayton Audio DSA90-PR 3″ Designer Series Aluminum Cone 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 black anodized aluminum cone and medium-roll rubber surround for clean excursion and long life. The possibilities with these passives are endless, from desktop two ways to portable battery powered speaker systems.
Specifications: • Fs: 43.7 Hz • Vas: 0.124 cu. ft. • Qms: 5.72 • Cms: 2.55 mm/N • Rms: 0.2 kg/s • Mms: 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
