Dayton Audio is proud to offer our customers a complete line of Reference Series Passive Radiators. These high quality, well-engineered passive radiators are carefully constructed using the same rigid anodized aluminum cone and cast frame as our world renowned Reference Series subwoofers, making them visually identical and a perfect match to the very popular line of drivers.
Each passive radiator employs the unique SMS (Sandwiched Mass Structure) design which keeps the majority of the mass centered between the surround and spider providing greater linearity by minimizing angular torque. These passives are also tunable using the included weights with the bolt-on mass adjustment assembly making them easily integrated into virtually any subwoofer design.
The RSS390-PR 15" passive radiator includes: 1 – Passive radiator 7 – 75 gram disk weights 1 – wing nut (for tuning) 1 – lock nut (for final assembly)
Note: Parameters above are for the passive only with no additional mass added. Parameters with additional mass added are listed in the table below.
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.
• Durable yet compliant suspension provides substantial linear travel and mechanical stability
• Rigid cast aluminum frame with thick black anodized aluminum cone
• Threaded rod with lock nut for easy adjustment of tuning frequency
• Includes 7-75 gram weighted disks for simple tuning adjustment
• Cosmetically identical to our popular Reference Series Subwoofer lines
