MTX FPR Shallow Car Audio Subwoofer

FPR Sub In Shallow Enclosure
(Enclosure not included)

Engineered for Better Sound

The FPR Series shallow mount subwoofers are designed to deliver true, hard-rocking subwoofer bass 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 behind the seat in a pickup truck, in convertibles, in the trunk with golf bags, strollers, or whatever other assorted goodies we grab for the drive.

Or maybe you want to custom mount your subs into some odd-shaped console. The FPR shallow depth often makes the difference.

Other shallow mount subwoofers in the market are not able to deliver full, rich subwoofer performance.They are often made more like midbass drivers, unable to play those powerful 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.


"i will admit i was leery at first but what the heck i could send the sub back if i did not like it.......well its not going back i'm keeping it plus working on getting one more.........it blew my mind the sound that can come from something as compact as this i have a single cab Z71 fits perfect and i'm 6ft i still have ALL my leg room.....a new be leaver"

Not all shallow subwoofers are created equal. MTX FPR subwoofers play as low in frequency and produce similar SPL output to regular subwoofers
in the same power class.

MTX FPR Car Audio Subwoofer Spider Venting

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.

FPR Series: Why Its The Best

  • Patented Shallow Design
    • Increased excursion
    • Superior volume displacement
  • Optimized for Sealed Enclosures
  • 0.60 cu ft Air Space Required
  • 300W-400W RMS Power

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.

  • Patented Flat Piston Design
  • True Subwoofer Low Frequency Performance
  • Spider Plateau Venting Mechanical Cooling Process Targets Cool Air at the Voice Coil
  • Extended Xmax for Increased Volume Displacement
  • High Roll Surround Increases Surface Diameter for Greater Volume Displacement
