MTX FPR Slimline sub


Available in 300WRMS 10inch or 400WRMS 12inch. FPR series subs.

MTX engineers have recognised 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.

Other shallow mount subwoofers in the market are not able to deliver full, rich subwoofer performance.They are often made more like mid-bass 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.

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.
