[QUOTE="emilimo701, post: 6842858, member: 622834"] Okay; I think I get it. If the wall is flush with the port opening, some air along the wall and close to the port will move along with air in the port due to friction (is friction the right term?) between air molecules in and around the port? I suspect this same thing happens with isolated ports but to a much lesser extent. It's funny, even my brother who was a physics major in college couldn't wrap his head around this. Sometimes, you just need to think outside the box (no pun intended... ha) WildBill: I was mainly using the bottom half of this page [URL="http://www.carstereo.com/help/Articles.cfm?id=31"]PORT Size Calculations and Formulas for WOOFER and Subwoofer BOXES[/URL] I guess I could reverse engineer to figure out the equation... unless anybody knows a place I could find it. But I'd still like to know... what effect does a corner have on a slot-port? Since ports are all about air-volume displacement, wouldn't you just (assuming 3" wide port) add 3 inches to the effective length of the port? (for example, in the RF diagram in my post above, the port would act the same as a 25.5 inch flat port) [/QUOTE]
