Joe X Posted November 30, 2013 Report Posted November 30, 2013 Now a 15.5H 8.5D1 5.5D2 57W will get you to 2 cubes @35.2Hz using 3 3" ports 20" long to the side. 3 3" ports is better port area than one 5" so I would take that approach.
Joe X Posted November 30, 2013 Report Posted November 30, 2013 ^^^ Yeah you could make the O.D. progressively larger and do some good router work to flare it out. I have thought about it as a project and may do it for shits and giggles. My lungs will hate me Here's how this guy did it: http://www.stevemeadedesigns.com/board/topic/91230-home-made-port-flares/
Greasemonkey2014 Posted December 2, 2013 Author Report Posted December 2, 2013 I cant find any ports online longer than 17"
Greasemonkey2014 Posted December 2, 2013 Author Report Posted December 2, 2013 http://www.the12volt.com/caraudio/boxcalcs.asp#por Is 1 3 inch port ok? I found this on Ebay http://www.ebay.com/itm/141119159254?_trksid=p2048036
CleanSierra Posted December 2, 2013 Report Posted December 2, 2013 That doesn't surprise me. Most companies only make 17" ports like PSP. That usually still extensions add well though, with a coupler. I did PVC pipe and where the pipe meet my box I used body filler to hide the seam. I also used a router to flare my edge. I need to do one on the Inside of the box as well, but I don't get port noise so it allows me to be lazy. I'll find a pic of what mine looks like Im not the one you want to try to troll. Just a fyi for you.

I found this on Ebay http://www.ebay.com/itm/141119159254?_trksid=p2048036 That eBay port looks like junk, plus it's only 12" long. Joe already figured out that of you're going to run 3" ports, that need to be all 20" in length Im not the one you want to try to troll. Just a fyi for you.

Im not the one you want to try to troll. Just a fyi for you.
