Kenwood KFC-WPS1200F 300mm Component Subwoofer
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 high quality materials such as a carbon-fibre cone and aluminum-cast basket for long-lasting reliability
