    1.56 ft^3. the port determines the frequency that your box is tuned to. you shouldn't just slice a port into the box. download WinISD and it will help you alot. www.linearteam.org

    what do u do to figure out the volume of a box i know its height*width*depth ok i have a box with a slanted front the bottom depth is 14in the top is 10in ok i think that u add those together and then divide that would be 12in then u take that and 12d*16w*14h is that how u get the volume

    you fid the area of the triangle and then add it to the area of your box. (L*W*H)/1728.

    Since the box is already built I wouldent suggest cutting a slot vent in unless your a good carpenter. Id go with a port 3-4" Diameter, then use a program to find the port depth, for the tuning freq your looking for. ill tell you if I get around to doing it. New computer gotta get the program:p

    What freq are yo looking to tune too.

    For 35hz tuning which is where I would go its good daily driver tuning is 14.8" of 4"diameter port
