[QUOTE="skylineTT, post: 7616365, member: 576995"] Well I built a box using RE box calc as always (they usually turn out sounding alright) and to achieve the tune I wanted, it called for a 28" port length in the back.. well the box wasnt wide enough for that so I took length off of the end of the port and glued it to the wall with the port width being the distance from the port to the wall.. you can see from the pics.. anyways, I figured that the port length would still be the same but just in a diff configuration and area was the same so tuning shouldnt suffer. well it did! seems to be tuned much higher than I aimed. I also used an FI X in the box which needs about .5 cubes more than what the box offers (didn't know at the time). anybody see any design flaws in the box or is it just that the sub wants a higher freq? thanks Calculated box. you can see the port is too long so i cut the end and placed it forward [IMG]http://i69.photobucket.com/albums/i57/all-names-were-taken/FIX.jpg[/IMG] built box [IMG]http://i69.photobucket.com/albums/i57/all-names-were-taken/IMAG0426.jpg[/IMG] 18" of port area btw [/QUOTE]
