Key Features

• SMS™ (Sandwich Mass System) permits greater linearity by minimizing angular torque
• 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

We are proud to offer our customers a complete line of Dayton Audio 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 Dayton Audio's 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.
