Box Build for (2) 10" L7's (2.9 @ 38 each) for ARMY-KILLA!

okay so wednesday, im not drivin my truck all the way there, me and a buddy are drivin to ames, im droppin my truck off at Cyclone Stereo to get an alarm, and he is drivin my moms car behind me,then we'll take my moms car to albert lea. id like to meet earlier in the day, so i can be back to pick up my truck with the new alarm on it. idk let me know whats the earliest you could be there.

 
sounds great, i think i could be there around 6, unless you need to meet earlier. i can get off work whenever i want just let me know as soon as you can, so i can tell my boss. if i just don't go to work at all after lunch i'd make it by 2, but i'd rather work till 4 and get some decent hours in, but i'll work with whatever you need. if the shop closes at whatever time and you need to meet early afternoon, just let me know asap and i'll make it work.

 
strait from the manual

S10L7

VENTED COMPACT (MINIMAL ENCLOSURE VOLUME)

1.25^3ft (35.4L) + port displacement

2.5x11.25" port, 19.75" long

power handling=450 rms

**** the bigger box is onluy 2.25^3 ft, 2.9 woulda been too big. i think shes okay. the tuning is under investigation...

how much Port area...I guestimated ~36 sq in. 12in tall and 3 in wide. With a box that is 1.4 cubes with 36sq in of port and 25 in of port length I got right at 47 hz.

If you were responding to me, I suppose I didn't pose the question very clearly. When the port is in the middle, as it is here, and the lengths have to make a turn, does that change the figure for port displacement? Because the lengths had to turn, does it displace more, less, or the same than if the box were long enough for the sides of the port to be straight?
