HELP: Stuck Between Ports...

[DeepBassAddiction]

Ok my question is... which of the 2 ports do you (in your opinion) think would be better...

CLASS: TRUNK

BOX: H 18", W 40", D 17", ⁴ft 5.69813...

SUBS: 2 15"s Soundstream Or DC...

Hz: 32

PORT 1: "L" Shaped Slot Port, W 8", H 16.5", L 51.48"...

PORT 2: Aero Port, D 8", L 17"...

Keep in mind ill be competing Amateur/Rookie... I'm not sure if that effects what kind of port I can have...

I have 5 tubes of 8" PVC pipe... I also have 6" but I want to go 8"...

Let me know what you guys think...

With the Pvc as a port you should flare each end. I would use a torch or heatgun and a stainless bowl thats the right size.

Your l-port doesn't have any air space left for subs and is tuned to 92 Hz before displacements and .68 cu ft after port displacement. Your Aeroport design is better but a little small on port area and with estimated displacement of just subs you are sitting at about 35 Hz. Net air space in the Aeroport box is a little under 5 cubes. Not enough air space IMO.

Yet again... rookie/amature/noob... idk what ur talking about wit the "l" port... I used the12volt.com's box/port calculators... so what did I do wrong?

I know buddy, I was actually thinking about makein Aero ports to sell them...

Nowhere near enough net volume for 2 15s. Would be good for 2 12s though.

If you are using a metal bowl, you are doing it wrong. If you want to flare PVC try this method:

Soundstream t-5 = 3⁴ft apeice...

DC lvl3 = 3⁴ft apeice...

So ill see if I can bring it up to 6-7⁴ft

If I add 1" to my depth ill bring it up to 6⁴... if I bring it up by 3" it will be 6.9⁴... would that work?

AFTER bracing, subwoofer, AND port displacements. A big L port eats into your net displacement in a big way. So shoot for like 9 cubes before any displacements. I'd seriously go with a couple nice 12's tuned around 34-35 and call it done in the space we know you have.

Port W 8"

Port H 16.5"

Box volume 6.801⁴ft

Hz 32

=

Port L 41.58"

Correct?
