JL 10TW3 Profile Gauge

With the popularity of under-seat truck subwoofer enclosures and other small profile or down-facing subwoofer applications such as consoles and up under the dash, the necessity to check subwoofer fit and clearance easily is important.


Use this lightweight Mobile Solutions Subwoofer Profile Gauge designed specifically for the JL Audio 10TW3 subwoofer to do trial fitting in the enclosure construction process. Doing so avoids removing the heavy subwoofer from its packaging, which exposes an open magnet structure to unnecessary microscopic sawdust and fiberglass dust, as well as exposing the cone, surround and dust cap areas of the JL Audio subwoofer to oils and solvents on the hands of the fabricator. 


The 10TW3 JL Audio Subwoofer Profile Gauge is silkscreened with the exact dimensional CAD profile of the 10TW3, including its specifications of power handling, multiple diameter measurements and mounting depth. 



  • Made from light and durable 1/4” Expanded PVC Plastic
  • Silkscreened with subwoofer CAD drawing, dimension and power handling specs
  • Eliminates need to remove subwoofer from packaging during fabrication
  • Reduces technician fatigue from lifting/moving subwoofers during fabrication process
  • Use as a sales tool in visualization of a customer’s potential subwoofer location(s)
  • Fabricate custom enclosures accurately even if the product is not yet in stock
  • Made in USA




  • Verify fitment in under-seat and rear cab wall truck subwoofer enclosures
