Dayton Audio DSA135-PR, 135mm (5in) Designer Series Aluminum Cone Passive Radiator

Dayton Audio DSA135-PR 5" Designer Series Aluminum Cone Passive Radiator 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.
