i have the dimensions and everything

45" wide, 12" deep and 21" tall. 4.4 cubes of airspace tuned to 35 hz. Has a 3" wide port with 58.5 sq. inches of port area

and i want to build it myself while my brothers in the hospital


question is can someone draw up the dimesions of the port or if your feeling very generous the whole box itself?

don't 4-get when you figure air space for tuning subtract sub displacement ant any displacement caused by the port or supports (gussets,etc...) should bring you total cubes down so chk and re chk

yea. http://www.reaudio.com/speaker_box/LPort_Box_Calc.html

go there. its easy to use. it configures all your displacement and all that jaz. only thing i would do is if possible make it 13" deep rather than 12" deep. add a little more space when you subtract all the displacement. Port board should be 8.5" long(back) . then another port board at the end of the 1st port that is 6" long. should make an L ....
