- 12-Inch (305mm) woofer with die-cast aluminium basket for solid sounds under all conditions
- Slipstream port eliminates port noise and provides distortion-free bass at high output levels
- System optimisation: amplifier is precisely matched with woofer, enclosure and Slipstream port to ensure best performance and value
- Signal-sensing turn-on automatically turns the subwoofer on and off when the head unit sends an audio signal; can be defeated for use with aftermarket radios that include a remote turn-on lead
