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 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: 46.99 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 Product Details Speaker Series Designer Series Model Number DSA215-PR List Price $24.99 Color Black Unit of Measure Each UPC 848791005060 Warranty - Parts 5 Years Warranty - Labor 5 Years Product Shipping Weight (lbs.) 1.15 Speaker Type Passive Radiator Nominal Diameter 8" Power Handling (max) -- Continuous Program Power -- Sensitivity -- Frequency Response -- Voice Coil Diameter -- Magnet Weight -- DC Resistance (Re) -- Voice Coil Inductance (Le) -- Resonant Frequency (Fs) 25.6 Hz Mechanical Q (Qms) 7.66 Electromagnetic Q (Qes) -- Total Q (Qts) -- Diaphragm Mass Inc.
