Thanks to all of you who helped with my cabinet building (from a previous post). I built it over the weekend (4 hours each, on Saturday and Sunday). The only thing that is left is routing out the edges, sanding the crap out of it, and... I either need a port of 6" X 7.5" long, or two 3" X 3.75" long ports. Which would you go with, and why? Also, when given the length of the port, is that measured from the inside or outside of the speaker baffle? I put in a hefty 1.25" thick baffle. So, do I add 1.25" to the length of the port? Any suggestions?
