[QUOTE="Phoenix Risen, post: 7116436, member: 623425"] as far as tuning i would say go as low as possible, best thing to do is get the box designed, figure out what the internal dimensions and gross volume is (LxWxH/1728) once you have the gross volume subtract the displacement of you woofers. to give you a rough net volume then figure out where you want to run your port, and what the distance is to the opposite wall, the length you can make your port is that distance minus the diameter of the port. then use the calculator to figure out what you can tune it too with that port length, by the way the usable length of the port when whole is 17" when you measure the port with the flares on you have to subtract 1" to give you the usable space. also the flares mount to the outside of the box with 1 flare and they run inside the box. how you put them together is up to you, anything from super glue to duct tape works [/QUOTE]
