Tuning is determined by NET Volume, Cross-sectional AREA of the port, and Length of the port.I had someone set me up with ports for THIS box that would tune my port(s) to 28 hz.
He told me to make three 2.75" x 2.75" ports that were 20" long.
I made one 18.75" x 1.8" port that was 20" long.
Same volume.
I'm still proud, if it whistles then I can be special.
"You need at least 35 square inches of port area in a 1:8 ratio or smaller."
How do I go about making 35 SQUARE inches of port area?
If you are interested, send me a PM with the max Dimensions you can fit in your vehicle. Also what type of vehicle.
I'll design you a perfect ported enclosure, with the needed volume, port area, and tuning. I include all specs, a detailed cut-sheet listing the exact size of all pieces needed to build the box, and a sketch. It's $10 via paypal, I've got plenty of references as well. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
