Dayton Audio DSA315-PR Specification Sheet

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 large tower designs to compact subwoofer systems.

Specifications: • Fs: 17.5 Hz • Vas: 190.8 liters • Qms: 6.23 • Cms: 0.58 mm/N • Rms: 2.5 kg/s • Mms: 142.6 g • Sd: 480 sq. cm. • Xmax: 13 mm • Dimensions: Overall diameter: 313.94 mm, Cutout diameter: 272.03 mm, Depth: 88.9 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
