Description
A 6½" woofer from Dayton Audio's Signature Series, with a one-piece concave black anodised aluminium cone, a polyimide former and an open cast aluminium frame. Dayton developed the series with Klippel testing for low distortion, and the vented former and elevated spider help it run cool.
Features
- Extensive Klippel LPM and LSI testing to optimise Bl symmetry and parameters
- Indexed cone/surround junction for a smooth transition and frequency response
- Polyimide formers for improved mechanical damping and a smooth frequency response
- One-piece concave black anodised aluminium cone
- Vented former and elevated spider for improved airflow
- Open cast aluminium frame for improved heat dissipation
- Countersunk stainless steel magnet badging for long-lasting looks
