5-6cu.ft. is too big imo, especially with that little amount of space. try 4cu.ft instead with a monster port.

with those dimensions it comes out to 11.67 cubes just for a box, cant tell me the port is going to be 5-6 cubes in displacement

Please explain this reasoning. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Well, depending on the power he may (or may not have available) the net volume could change. 5-6 cubes is 2.5-3 cubes per sub which isn't all that crazy for some 12's. Assuming he might be low on power (since those SPL's can take an ***-load), a bigger box will be a little more efficient on the lower power he might have available.

If marco has you taken care then nevermind. But if you're still in need of a cutsheet, hit me up.

another pm coming your way. with a few ?'s

its probably over braced ( 3 sdies are doubled. if thats too much wood i can tell you how to make it work without extra 2 walls)

port walls:

13.25x16.75 (one side cut at 45* angle)

3.1x16.75(also 1 side cut at 45*) (will show up as 4.6 in the sketches... i forgot about the baffle adding to the length of port ftl haha

6.625x16.75 (45 cut on both sides)

45's:

1 8.5x16.75 inside port corner.

2 4x16.75 opposite port. on top and bottom.

Top and bottom:

Top (2x) 36x19.75 ( sub cutout and port through both. port .75 from side and 1.5 from front and back 16.75x5.25, subs centered front to back and 7 inches from side/port opening. 11" cutout) can also flush mount if you'd like. willing to help you work that out.

bottom 36x19.75

left and right:

both 16.75x21.75

front and back:

both: inside(smaller) 34.5x21.75

outside(longer) 36x21.75

yeah i forgot to resize them... pmed back.. with a list of some bandpass designers... im not comfortable with them and would rather not supply you a bad design.
