Aero Port guide?

[MCarmer 10+ year member]

Hello all I have a few questions but first some information for you.

This is for my daily driving car, no competition use just music daily. Id love to get a little more out of the box and subs i currently have by porting it.

I got a dual 15 sealed enclosure, its approx 3.22 cubes per side after driver displacement.

I'm going to port both sides of the enclosure and Im aiming for around 38hz tuning since i listen to a good bit of music.

I am going to EITHER USE 2 3 inch(ID) ports or a single 6 inch(ID) port for each side of the enclosure.

ACCORDING TO:

http://www.psp-inc.com/psp-inc.com/cgi-bin/port_length_calculator.cgi

Volume of Box in Cubic Feet: 3.22

Tuning frequency: 38

Port diameter: 3

Number of Ports: 2

Straight Length Port required 6.0

Flare Length Port required 7.0

=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-

So would it be best to use 2 3 inch(ID) tubes 7 inches long each total including the flared end.

OR

Should i pony up the extra bit of cash and just use 1 6 inch(ID) that's 13 inches long including the flared end.

So my questions to those who have experience in this or knowledge of using these ports are:

1. 2 3 inch ports per side are cheaper than 1 6 inch port per side, BUT would they both sound and work the same as far as tuning the box? IF not then why?

2. Should i put the ports on the face of the enclosure? OR on the sides of the enclosure?(IF ON THE SIDES, THEY SHOULD GO ON THE BACK OR FRONT?)

Go with a single 6, because for larger future setups the 3 in ports will be useless.

What kind of car do you have? That will determine the box design.

Unless using the ports externally you need to calculate for port displacement.

the box takes up pretty much 3/4 of the trunk, its in my daily driver accord.

I wont do a upgrade with this box and car, this is for my daily driver accord, i dont want to upgrade electrical, add batteries or anything else, its used for trips and back and forth a-b driving.

If i go with more power & bigger sub or subs in this car i will build a new box for it as this one is a pre-fabed sealed box, Im going to convert to ported.

If i do (1)6 inch port off each side of the box i can stick them outta the box about 4 in each it will come close to the sides of the trunk, if i use (2)3 inch ports on the face for each chamber i can stick them out as far as i want because i can just move the box back a little.

If i do a single 6 inch port on each chamber i will have to do it on the side of the box because the face of the box doesnt have a 6 inch spot free to put it there.

Which would be better using a single 6 inch port on each chamber, aiming up or out the side?
