Posted February 26, 201015 yr ok, so i have the dimensions for everything, but i want to make sure if its all good, also if someone could do a sketch of it? 2 - 15" nightshades1 saz-3500D99 s10 ext cabsubs forward, port in the middle firing up but along the back wall of the box.box height - 27 depth - 14.5 Length - 46.5Port height - 6 width - 16 length - 26.25net air space 6.68ft3. port area 96.00 in2. @32.19
February 26, 201015 yr Is your net without driver displacement and end correction? Assuming a maximum of three inches in the method.I get 1.46ft3 of port volume and a gross of 8.63ft3. Is this what you started with?

Is this what you started with?yes the calc. i used counts for end correction, and thats after all displacement. i used (exposports) calc. i believe he is on ssa forums aswell.
February 27, 201015 yr Author could i also get these numbers checked out to make sure that this is correct, this is after all displacement, and port correction. the port cut (piece of wood) would be 17.5" long, and use the side of the box for the port to bend.. subs up, port up (on the end)box height - 16 depth - 24.75 Length - 47Port height - 6.5 width - 14.5 length - 24?net air space 7.11ft3. port area 94.25 in2. @31.83im debating on the two box's as subs up port up is louder...
February 28, 201015 yr Author What are your displacements?ok, well i think im going to go with that 2nd desgin, sub up, port up, i fixed my current box like that, but its tuned to 36, and it gets loud, but is not hitting the lows i want it to, its 6.7 cubes at 36hz. so bigger box, lower tuning. and all my calculations i gave you, is including all displacement and port correcting, i just want to see if they are right, and maybe if someone can do a visual of it and if the port is right, but my displacement is .42
February 28, 201015 yr Every thing looks fine, I got a little bit different numbers but they are close enough. I got 7.04ft^3 @ 31.64hz
