Features:
- Kenwood's flagship subwoofer, the KFC-WPS1000F, delivers unbelievable performance as it boasts a peak power output of 1000W
- Reassuring durability even during long hours of high-output operation can also be enjoyed as the speaker unit is designed to dissipate heat effectively away from the motor system
- A die-cast Aluminum basket is employed to further reduce heat and improve power-handling characteristics while multiple fins enhance ventilation and rigidity for supporting the large motor
- Four vents are positioned around the basket to ensure that the entire subwoofer is always properly cooled
- Compared to existing models, the new flat subwoofers in the 2007 lineup are approximately 40% slimmer in height
- This makes them ideal for installation in the tightest of spaces such as behind or under the seats
- The subwoofer also uses highquality materials such as a carbon-fiber cone and Aluminum-cast basket for long-lasting reliability
