nocturnalrites101 Posted August 3, 2015 Report Posted August 3, 2015 I was playing around with a sub box designs while waiting for my 24 to ship. I came up with this when bored12 cu ft Net Both sealed and Ported. 1:1 ratio. Ported Side Tuned to 26.5 Hz, 227.78 sq of Port. Double layers of 3/4 inch all the way around with a sheet of 1 inch thick plexi to view the sub when you fold down the rear seats. port fires into the rear doors of the Suburban.Thoughts?
Joe X Posted August 3, 2015 Report Posted August 3, 2015 If you tune that bandpass enclosure to 26.5 Hz then you will play very little above that frequency,
CleanSierra Posted August 3, 2015 Report Posted August 3, 2015 Was 26.5Hz a typo? Im not the one you want to try to troll. Just a fyi for you.
nocturnalrites101 Posted August 4, 2015 Author Report Posted August 4, 2015 Played with designs alittle more10.5 cu ft sealed 16 ported tuned to 40hz 455. sq in of portgetting more dialed in
nocturnalrites101 Posted August 4, 2015 Author Report Posted August 4, 2015 gives you a feel of the massive portall done for now thoughts?
db_speakerbox Posted August 4, 2015 Report Posted August 4, 2015 #2 is a way better design. Not sure why you are doing the port that way tho. I would raise tuning to 42hz and shrink down the port area to around 300 sqin. That much port area you are going to lose a lot of port velocity. Keep in mind the first pic is no port installed.
db_speakerbox Posted August 4, 2015 Report Posted August 4, 2015 double post. also sorry about the poster size pics.
nocturnalrites101 Posted August 4, 2015 Author Report Posted August 4, 2015 double post. also sorry about the poster size pics. I dont want the sub to load off the port in anyway shape or from. Im want it to center load off the rear door as the truck seems to like that the most in terms of port placement, im attempting to have no obstructions between the sub and the port for nice smooth airflow. this is why the port is so goofy. I may play with it more later. But as of now 40hz is tough. those 2hz more is going to be extremely tough while shirking the port 150 sq in's

So what port velocity do you consider to be ideal?
