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 want loud, clear music. Not anymore!

Engineered for Better Sound

The FPR Series shallow mount subwoofers are designed to deliver true subwoofer sound in a form that has a mounting depth of 3.325". MTX engineers recognized that there are scenarios where you just can't fit a full size subwoofer like behind the seat in a pickup truck, in convertibles, in the trunk with golf bags, strollers, or whatever other assorted goodies we drive around with. Other shallow mount subwoofers in the market are not able to deliver true subwoofer performance, they are more like midbass drivers, unable to play those truly low notes that make owning a subwoofer fun. The result of this research is the patented One Piece Spider Cone Assembly design that delivers true subwoofer performance in an ultra compact design.

The Design

The FPR is a patented and unique in that the cone is attached directly to the spider. This design allows the spider to better control the cone movement especially its one way motion, Xmax. The angled design of the basket allows the cone to travel farther than a conventional subwoofer which would be limited by the spider's connection to the basket. Additionally, the cone utilizes a curved design where it connects to the surround. This not only advantageous as it more easily connects to the spider but it also increases the surface diameter of the cone. The increased Xmax and surface diameter gained as a result of the design allow the subwoofer to move more air and generate higher SPL.

Thermal Management

The FPR subwoofer uses two design elements to regulate the high temperatures generated at the voice coil. Like other MTX subwoofers the FPR series uses the mechanical cooling process, Spider Plateau Venting, to continually circulate air to the voice coil eliminating distortion resulting from excessive temperatures. Additionally, the aluminum dustcap in the cone connects directly to the voice coil and transfers heat away from the voice coil further ensuring reliability and sound quality.
