[QUOTE="Mongo12, post: 7791989, member: 642084"] ok so not to sound dumb.. but is the port 18.5 inches or 39 inches in your graph? or would i have to add 20.5" to the 18.5 inch port to get 30Hz? 30hz sounds good to me since the probox is (i was told) tuned to around 45.. [IMG]http://img62.imageshack.us/img62/5391/scaledbox1.jpg[/IMG] the redline is scaled to 18.5 inches and the yellow shows where it would be at 39 inches .. unless i misunderstood your dimensions.
