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 Audios 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 stand mount two-ways to compact subwoofer systems.
Specifications: • Fs: 25.6 Hz • Vas: 36.7 liters • Qms: 7.66 • Cms: 0.58 mm/N • Rms: 1.4 kg/s • Mms: 67 g • Sd: 211.2 sq. cm. • Xmax: 11 mm • Dimensions: Overall diameter: 175.51 mm, Cutout diameter: 144.02 mm, Depth: 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 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
