The Kenwood Excelon XM1041BL is a premium 10-inch marine and motorsports subwoofer built for boats, UTVs, motorcycles, Jeeps, and off-road vehicles. The “BL” version features a black grille and basket finish while offering the same rugged all-weather performance and RGB lighting system as the white XM1041WL model. One of the biggest advantages of the XM1041BL is its free-air/infinite-baffle capability, making it ideal for installs where a traditional enclosure is difficult or impossible. It can also be used in sealed enclosures for tighter bass response.
