Additional Information
Many vehicles today have limited space. Having a large enclosure to get the bass you want may not fit your lifestyle. Limited space has traditionally meant limited options for those who wants loud, clear music. Not anymore! FP Series subwoofers are the next incarnation in the MTX shallow subwoofer family. Measuring only 3.325" deep these subwoofers will fit just about anywhere. Utilizing a patent pending "Flat Piston" design, the FP Series subwoofers achieve excursion levels that are unparalleled in the "thin" subwoofer market. What does this all mean? It means that if you want to get an extreme amount of bass from a very small space (such as you car door), FP Series subwoofers are the solution for you. They are available in 10" and 12" sizes and are available in single 4Ω or single 2Ω configurations.
