Bills Posted July 12, 2008 Report Posted July 12, 2008 I know this question comes up about once a week it seams. But since I'm bored at work right now, I thought I would post this and ask what are the following formulas for diff ports: Slot port..... Square Port..... Aero or round port..... Help would be awsome to get all of this cleared up and if a Mod or Admin could make this a "pinned" or "sticky" thread, that would be sweet so this could help alot of people. I know I would use it alot. thanks!!! Bills KwB Team DC Audio Midwest captain

Derrick824 Posted July 13, 2008 Report Posted July 13, 2008 Straight from Precision Ports website. 1. Calculate length of port needed: 2. Determine proper speaker & port placement before cutting any holes. The Precision Port™ should be placed at least one port diameter away from any inside walls, if possible. 3. Trim center tube to 5" shorter than Lv from step one. 4. The Precision Port™ should be 1" longer than Lv when assembled. 5. Once placement has been determined cut the proper size hole. (Cut hole to the diameter of the flare side of the inside flare) 6. When the length has been achieved the Precision Port™ can be glued together using ordinary ABS adhesive or similar type glue. Once pieces are assembled with ABS adhesive, pieces can not be taken apart. I use electrical tape so they can be easily disassembled for tuning changes. Assemble the Precision Port™ in the following manner. 1. Attach connecting rings to flared ends. 2. Slide flared ends, with connecting rings attached, over tube section. 7. Insert the Precision Port™ into enclosure and secure with screws, holes are drilled for #6 drywall screws for a flush appearance.
Derrick824 Posted July 13, 2008 Report Posted July 13, 2008 or you could just use the port calculator on PSP's website http://www.psp-inc.com/ or you could download WinISD and let it do the work for you http://www.linearteam.dk/
