FPR series subwoofers set the standard for shallow mount subwoofer performance.  

Putting a huge enclosure in your trunk may not be practical for your lifestyle or maybe you drive a truck and don't have any room for an enclosure but you still want to upgrade your sound system with some extra bass.  FPR subwoofers are the ideal solution.  Designed with less than 3.5" of mounting depth these subwoofers can perform in extremely small enclosures, as small as 0.6 cubic feet.

The FPR use a patent pending design in which the spider is attached to the front plate rather than the basket.  This allows the subwoofer to achieve greater excursion resulting in more volume displacement.  The subwoofer also employs mechanical cooling with MTX's Spider Plateau Venting which continuously targets cool air at the voice coil.  Finally the cone utilizes a bubble shape that increases the cone strength as well as an aluminum dust cap which  dissipates heat away from the voice coil.

Additionally, FPR series subwoofers overcome the problems that other shallow mount subwoofers face in that they are able to play extremely low frequencies.  This is important especially for Rap and Hip-Hop listeners that have a certain expectation for what they are going to hear.  The 12" version can play as low as 22Hz and the 10" version can play down to 25Hz.  All in all the MTX FPR series is the ideal choice for anyone that wants an awesome bass experience with the convenience and benefits of a shallow mount design.
