what do you use to figure ported box volume?

ive used 3 different box calculators and got 3 different answers

14" H x 32" W x 14" D i got 3.1^ , 2.7^, and 2.1^

as you can see, all are vastly different.

for port size i have 12.5" H x 2.25" W, w/ a length of 26.75"
while on another program i got 24.125.

which is correct?

what do you use or do to find the correct box volume?

nvm what was stated

can someone tell me if my port length is correct for the stated box size tho?

14H x 32W x 14D

port size i have 12.5" H x 2.25" W, w/ a length of 26.75"

check for any problems in my dimensions, and port length. im only 16, and just got into car audio about 2 months ago. im trying to learn quickly so i dont have to ask any questions.

whats not stated:

Not To Scale.

Port Size: 13" H x 2" W

inner port wall that is not stated: wall length should be 12.54"

comes out to be 2.8ish^ not 2.7 (not that it will make a big difference)

see any mistakes or anything? my 1st time drawing up plans and figuring out port length. so there will probably be a mistake or two (hopefully not tho :) )

any errors? i just drew this up

I dont remember you saying how many drivers and their displacement either, but from the info given its 2.7 cubes tuned at 29-30hz

1 12" driver

really about 2.6-2.7^3 after sub displacement

tuned to 30hz

dimensions are given
