calculation help????????

[UMGixxer]

these dimensions are supposed to give 4.5ft^3 @ 33Hz, can someone please explain to me how to arrive at this from the following dimensions

dimensions are:
bottom 35x23
top 35x23
left 22.25x13.5
right 21.5x13.5
back 35x13.5
front 29.75x13.5
port 17x13.5

anyone???

[ABSOLUTEAUDIO]

how long is the port?

[cj407]

who designed that? and how wide is the port?

[cj407]

port would obviously be 17"

i come up with a box thats 4.196 ft^3 @ 33 hz....not 4.5

[schrummy]

Learn how to do it yourself :fyi:

[cj407]

yea buck...learn how to do it urself and not get PWK to design ur box....jk :D

those are external dimensions, and a guy did that for me on another forum, i know how to calculate the volume of a sealed box just not sure about port and how it affects the volume

the two side pieces, the front, and back pieces sit in between the top and bottom piece
