Superjay Posted January 21, 2011 Report Share Posted January 21, 2011 to do it correctly you mold the port into the enclosure. make a ring like you would to mount the sub and mount the tube to it (aero or straight) or, I've used pantyhose to make the port tube...you can get some pretty cool shapes and eliminate turbulence by making the port opening smoothed into the face of the enclosure. reinforcing the vent is a little difficult, but it's only an access issue Quote Principal JTech Consulting - Leader in 12-Volt Training and Product PlanningIt's not about how much power you have, but how well you use it Link to comment Share on other sites More sharing options...
