H4.5 W16.5 L16 with this i get port area of 74.25.

now if i do another port the same size will i get 148.5 port area right???

and have a tune of ~32hz?

thanks

[is this right?]

You would have to calculate that as if it were 2 separate boxes...

can i have an example. please?

thanks

here what im lookin to do.

ghetto paint again

[is this right?]

sorry double post

http://www.carstereo.com/help/Articles.cfm?id=31

at the bottom of the page do i use this?

Quantity of ports 2

Enter Enclosure Volume 9.17

Enter Desired Tuning Frequency 32hz

sloted port -yes

Enter Height 4.5"

Enter Width 16"

Vent Length 26.32"

is this the correct port length?

[is this right?]

Big no.

hahaha

what would be the way?

THANKS

CHRIS

[is this right?]

bump again. sorry/

i didnt want to make a new thread so ill post my qestion here.

ok here it is.

i have a port that is W 4.5" H 32.5" L 20" with this i have a tune of 34.4hz

box is H30 W46 D14

Question

- can i do half of each height nd width nd length and with that make two slot ports and have the same tune or will it be different?

example

Height 32.5" = 16.25"

width 4.5" = 2.25

length 20" = 10"

thanks

To get the best sound & avoid mounting depth problems, locate the sub as far away away from the port opening...otherwise, like you said, just add a spacer...

this how it should look like

sorry ghetto paint..

THANKS ALL TO HELP ME! LEARN ALOT.

[is this right?]

yea, you'd be ok, as long as it's tuned @34hz....

at the bottom of the carstereo page , you could calculate port length...

34.85hz seems ok, although it's leaning more towards 35hz, especially if you're gonna brace the box & add corner fills...

sound good.

yea i understand.

now all that done with i think the sub gonna run into the port since it gonna be L.

but im going to add another baffle over it so it should space it out more.

[is this right?]

Ya a negative port length would kinda be impossible. at the bottom of the page in the background you can calculate ideal port length.

ok i done that i come up with 27in

but i still have - number on torres cal.?

[is this right?]

make your port longer til it hits 34hz or make your port area bigger for 36hz...

146.25 is ok, 146.03 is just your minimum @34hz...

not sure what the negative number could mean...???

just keep playing with it, til it all falls into place...

so if i go bigger then 146.25 im ok right?

yeah im kind of confused abt the negative...anyone else can help with this?

ok i change the length number to 27in cames out the 34.85hz

thanks.

-CHRIS

[is this right?]

first jst wanna say big thanks to the people who are helping me out!!!

got some qestions.

what in blue. tune i want 34hz but torres cal. say 36hz?

what is in red. very close to port size cal. (146.03) nd torres cal. is (146.25) with this number it is tune to 34hz correct?

one more question i see a ( - negitive number) could this mean bad??? what circle in yellow.

thanks so much!!!

-Chris

ps i change the height of box so the port can clear the top part of the sits.

[is this right?]

since you're not doing a round or square port, you can ignore the diameter & length for a square vent...

right, you would have to come up with at least 137.44sq.in.(@32hz) of port area to avoid port noise....

ok sound good.

im play around more with torres cal. nd if i come up with something good ill post it up again. to verify if it correct.

thanks so much guys.

-CHRIS

[is this right?]

not to thread jack but why's everyone elses version of this calc have the port bends button? was there an updated version i have to download? anyway back on topic, new design looks much better

i beleve there was an update.

port area is still way too small, use this site to help you figure out your minimum port area for that sub:

http://www.carstereo.com/help/Articles.cfm?id=31

ok i done that..

i get Minimum Diameter 13.23in

Minimum Area =137.44in

Length of a side

for a square vent =11.72in

i am think i have to come up with 137.44ish for the box port area. right??

sorry for so much questions. im learing nd every help will appratade.

[is this right?]

Says the depth of the box is only 14, then the port length is 20...you need to click "Check if Port Bends"

ok i done it.

[is this right?]

sorry for double post.

jst mess around abit more. hope this one look better then the first.

re box cal. if this good port for the sub i will be going this one.

PS box is going chevy s10 ext cab.

thanks

-chris

[is this right?]

sorry. im still not using to makin port with torres Box cal.

im use to doing it by RE cal. i just wanted to try something different.

well i figure go big or go home. as from the site (fi audio) saying 5-10cuft. ported box.

im running rockford fosgate t2000.1bd

let me ask again.

can anyone give me a design that is best with the sub.

hw much room i got to play with. H34 W46 D14

nothing over that.

thanks

chris

[is this right?]

[Fi Audio question]

just email scott or nick @ficaraudio.com and see if they still have youre invoice, they probally do

dont mean to sound dumb but what the emails?

is it [email protected]?

[Fi Audio question]

I'd say it's woth a shot atleast. If not I'd do what was mentioned earlier and just get two new ones and sell that one.

im trying to remember. what i order. i knw it not full loaded.

but it was close to be.

[Fi Audio question]

if you bought it straight from Fi get ahold of them and see if they still got your purchase on record.

never thought they keep them.

to be excacted i found a pic that has the date of the sub when i got it. 2/19/09
