general-purpose passives suitable for replacement or for new construction. Built
to be a perfect match for the Designer Series drivers, these passive radiators
feature the same steel frame, rubber surround, and anodized aluminum cone making
them visually identical.

Perfect match for Dayton Audio's aluminum 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 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 portable battery
powered speaker systems.
Specifications:
• Fs: 27.9 Hz
• Vas: 0.43 ft³
• Qms: 3.7
• Cms: 1.51 mm/N
•
Rms: 1.0 kg/s
• Mms: 21.5 g
• Sd: 75.4 sq. cm.
• Xmax: 8 mm
• Dimensions:
Overall diameter: 5.31", Cutout diameter: 4.40", Depth: 1.5".
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
