My current box has a slot port with 36sq in of port area. Im thinking about building a new box with a single 6" aero port or 2 4" aero's. Should i benefit in anyway with the aero?

i wonder the same thing myself. im just out for the street bass though..

i've never been able to hear a difference between aero's and a slot port, but i work with less power also. i find aero's easier to use, especially if i'm not working with a square box.

My setup is for street bass too no comps. I have no complaints about slot ports i was just curious becuase they seem pretty popular.

they're gaining popularity because they are so much easier to use. you can switch out daily or comp tuning easier with aeros then making an interchangeable slot port. also saves you some space too.

u also have to sacrifice port area if u want a lower tuning......

The big benefits to round ports is they take up less displacement and are easier to adjust tuning. The downside is the added cost. You might gain a few tenths switching from a slot to round port but there are many variables. If you're not competing and looking for every last tenth then IMO its not worth the change.

so if someone suggested i make a 2.3 cube slot port with 36 inches of port area tuned to 34 hz, could i get away with making an aero port box smaller and get the same results?

if so, what would all that translate too in an aero box?

Space (install dependent).
Ability to change tuning easily.
Can go above 10% mach on vent velocity and not experience much port noise.

Haha...i'm trying to take the topic seriously, but the whole Farva thing just cracks me up!

Its like a retarded midget trying to tell you his name...i can't stop laughing!

Interesting! Glad to have been able to provide a laugh, I think I choose a good handle for this board. Now give me my cola.

i am running an aero and they are nice since they take up less space and no port noise and some say they are slightly louder

what is the common rule when judging port area for subs with aeros

i have 2 12" small fi x series 400 watts subs im going to modify my 2.0 gross interior 15" box's i have for my oz 15's and make baffle for a 12. but i dont no what size aero i need for 1 12 in probably 1.9 net. im adding exterior ports. and will vent to rear deck probably. but i have 2 individual 15" boxs

For aeroport setups I calculate port area off of cone area. There was a formula floating around this board a while back but I'm too lazy to search for it. For a single 12 w/ low power I would use a single 4" port. For higher power spl oriented setups use two 4" ports or a single 6" port per 12" sub.

and how would u figure that and prove it

well first off u have half the port area u need and two ur dumb. so i win:fyi:

well mobeious designed the box so if it needed more port area wouldnt he of put another aero in it or wat

and if i want to i can always go and add another port in it if i really need it

and i will loose .16cuft of airspace and will i gain anything with another 6" aero how much louder would it be or would i not notice it

I'm just guessing, but maybe it has to do with air movement, why are straws round instead of squared??

yea i couldnt of really went with 2 6" aeros since the aeros would of been around 23.5 long and the box is only 26.5 long inside so only would of gave around 3 inches between the box and the port doubt that would work that good

the box dimensions are 32 tall 28 deep and 13.5 wide thats external and the subs are facing the roof and port is firing back

so one 6 inch aero would of been the only possible way i think


so being around 5.2net tuned at 33-34hz on 1500rms in a f150 truck wat should i be doing on the TL

extended cab i assume? i saw a guy yest. do a 145 at the headrest with 4 8's and 1200 watts. i saw a guy do a 145 with 1500 watts and 1 15. so idk man get it done at the headrest and tell us.

its in a f150 king ranch with the bucket seats and console in the back i removed the console and have a box back there that sits between the rear seats with subs towards the roof and port firing towards the back wall

if i turned the box around where the port firward forward i bet it would be louder or no it wouldnt?

are you familar with the kind of truck and the way the box is in the truck or do i need pics to help explain better

u wont' know anything for sure until you get in there and start testing. every car does different stuff when it comes to sound pressure

yea i am aware of that but not sure where i can get it tested at i have one audio shop locally but i am sure he would charge me alot to test it

so its like a big single cab? sub up port toward the driver side on the side of the box would prob be the loudest. i dont understand how u got the port firing toward the back tho:wow:

EDIT: nvm i looked it up and it is an ext. cab unless i saw the wrong pic.

why are tubes/hoses/pipes/etc round instead of square? Makes no sense:confused:

lmao bad arguement. Why would they be square? Comfort, probably easier to manufacture, more flexibility, etc, etc

My next box I'm switching to aeros just to see if I can tell a difference. The box is for a single 15 BTL in a ex-cab dakota. Sub up ports up behind the driver and 2 4in aero's tuned to 35hz.

try sub up or sub forward. port to the driver side with 1 8" pvc tuned to 35. should be LOUD.

one thing to note with though. While aeroports may make your box louder, it doesn't mean you'll pressurize your cabin any more than before (which is what results in a higher SPL score). For example I had a 15 crystal sub in a slot ported box, did 150db at the port. I also had a kicker L7 12 with aeroports doing 156db at the port. The crystal was louder on the mic by 0.6db even though the 12" box with aeros was louder at the port. you have to pressurize that cabin!

I've heard that sub toward drivers side was loudest on the meter but I really dont hit any comps. its just for daily. You think it would still work better than port up? Also why 1 8" aero?

all of the loud trucks i have seen at the headrest either do sub up or sub forward port side. one guy with one xxx 12 did a 145 at the headrest in a NICE sounding box sub forward port driver side. idk the watts tho. i mean 4 8's 1200 watts, 145 is a good score to me in a daily box. so it must work. i 8" is enough area for a 4 cube box and its easier to put in and brace one port than two to me. plus two 4 inchers isnt enough IMO.

i think u might have got higher at the port because of the smaller ports. i am pretty sure in port wars the port is almost like a straw.

i know the box is huge and may not look the best but i couldnt afford a fiberglassed box to fit better between the seats and match and blend better in the future i plan to do that or do a blow through since i have a bed cover

but everyone in the car can still see one another and talk to each other with no problem and i have the amps mounted behind the rear seats and still need to hide those wires somehow comming from the back battery to the amps and the wires in the port will hook them to the box terminal once i get bigger speaker wire

its bolted down haha and i dont think its going anywhere anyway it would hit the roof before comming over through to the front

but i mean only way i can get loud as i wanted and it does get loud i wanted to glass up the backk wall and make it unique where it wouldnt be as tall but i didnt have the funds

Wow man, for a truck that nice I would really look into making a better designed or a better placed box. Any room under the seats?

king ranch
08-25-2008, 01:38 AM
under the seats impossible because it has the stadium seating the floor in the back rises up to mount the seats i have about 3 inches from the floor to seat and maybe 6 inches long if that, only way to get subs in the truck is like i have it however to look better i could of not went with as many subs or as big subs but i didnt want just a little bass lol

and no room behind seat i have problems getting a amp behind the seat that is only 2 inches thick i have to push the seat back against the amp and push the lever down to lok the seat in place its that tight

only way possible is remove bucket seats get a bench seat and possibly put 2 12's under or like the seats i have now i would have to raise the seats 2 inches and move them forward 3 inches to get subs behind the back seats and i would have to go sealed and have very small airspace and make the truck not as comfortable because the moving of the seats

but in the future i plan on removing that box putting the console back and putting a blow through in the truck with 4 15's or 6 15's or 8 12's w/e i can fit and will be the loudest

this truck is my project truck soon will have 26's and 4.56 gears or bigger and a supercharger its 2001 and only 80k miles on it so only around 10k a year not bad and plan to restain all the seats and put new carpet in it so it will be basically brand new
