Description
The Dayton Audio Designer Series passive radiators are excellent 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 anodised aluminium cone making them visually identical.
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 anodised aluminium 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.
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
Features
- Perfect match for Dayton Audio's aluminium 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
