Dayton Audio Passive Radiators are excellent general-purpose passives suitable for replacement or for new construction.

Dayton Audio 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, the passives match the Shielded DVC line of subwoofers, 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 small active/passive subwoofer systems.


• Smooth, low-distortion bass performance
• Robust construction with high-excursion design
• Elegant appearance adds class to any project
• Cosmetic match for Designer Series woofers
