[QUOTE="Immacomputer, post: 2779566, member: 570419"] Are the internal dimensions of 14.5x10x25.75 including or excluding the port? You need to be specific as it will have a huge effect on the actual volume of the enclosure. If that is NOT including the port, you're looking at 2.16 cubic feet. That puts your tuning at a little over 50hz. A 1.75" wide port that is 10" tall and 12" long will bring the tuning to 36hz and I would not make it any smaller than that. I really doubt the enclosure will sound decent like that. Well, I screwed around in sketchup and this might work for you: [IMG]http://i11.tinypic.com/42ne3rs.png[/IMG] You need to add three panels to the port. Do NOT put them on the outside wall of the enclosure because that will not get you the length you need.
