Built to be a perfect match for the Designer Series drivers, these passive radiators feature the same steel frame, rubber surround, and treated paper cone making them visually identical.
Key Features
• Perfect match for Dayton Audio's paper cone Designer Series drivers
• Allows tuning small enclosures lower than using conventional ports
• Rear mounted screw allows easy mass adjustment for custom tuning
• Cosmetic frame edge looks great even when surface mounted
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
