Triad Subwoofer Silver FlexSub

Triad’s new FlexSubs allow you to add bass to an audio system with the very least amount of visual impact. We named them “FlexSub” because of their installation flexibility. The Silver FlexSub is a version of Triad’s powerful Silver Sub that has been configured to install behind a ceiling, cabinet toekick, baseboard, wall, or crawl space. The bass is channeled through a damped, coiled, expandable, flexible tube that terminates with one of two grills; a very small standard Triad grill, or a vent outlet.


  • Flexible installation with remote mounting.
  • Triad AcoustiPerf metal grill (size S) available in three designs:
  • Narrow, Wide, and Frameless or Vent Register (7-1/2″ x 12-1/2″)
  • Custom paint available.
