Description
Dayton Audio's 18" Reference Series passive radiator, for tuning small enclosures lower than a conventional port allows. It has a thick black anodised aluminium cone, a cast aluminium frame and a rubber surround, and its long travel suits today's high-excursion subwoofers. Eight 75 g weight discs are included for tuning.
Features
- SMS (Sandwich Mass System) permits greater linearity by minimising angular torque
- Durable yet compliant suspension provides substantial linear travel and mechanical stability
- Rigid cast aluminium frame with thick black anodised aluminium cone
- Threaded rod with lock nut for easy adjustment of tuning frequency
- Includes eight 75 g weight discs for simple tuning adjustment
- Cosmetically identical to Dayton Audio's Reference Series subwoofers
