hey guys i'm going to try a different stlye port than my slot port that ive always done and i'm wondering if anyone knows where to find some aero ports and whitch would sound better 2 6" ports or 3 4" ? its going to be for my 12" btl d2 daily. on my saz2000d amp box will be 2.5ft3 i'm looking for a low bass my current box is 32-33hz but my port area is too big and the sub tends to bottom out at high volume. and does anyone have any views if it would make a bigger difference going to a 30hz tuning ?

Whats the goal?

Louder or lower?

1) it's more than loud lol but I'm just curious if dropping it to 30 would sacrifice allot of that loudness or by ear would i notice?

2) would going from 2-6" aero ports to 3-4" ports change the sound at all

With Aero ports you can use roughly 50% less port area than a standard slot port.

As far any audible SQ or SPL increases/decreases, I don't think you will be able to notice unless you meter it.

I just built a box for my IA DR 18" using 4 4" Aeros and I like the result so far.

A tuning of 30hz will give you a flatter response with a nice gradual roll off at tuning. Tuning higher will give you louder bump and sharper roll off at tuning.

ok so i listen to alot of hard rock like metlica and rap do you have any thoughts on the tuneing that would sound good for both ? i think mine is close to 32hz and it's good for both but havent heard other tunings do you suggest i keep it at 32 ?

and does anyone know a good site to order some ports from ?

My personal preference has always been 35-38hz. I listen to mainly metal, rock and very little rap/hip hop.

Pasrts Express has the Precision Ports (Aeros)

BTL's aren't able to bottom out because of the huge bumped back plate

so would that be a clipped signal i'm hearing then?

bc my port is 4" by 13.5" by 41"long and internal volume with sub subtraction is 2.5ft 3 port area would be 54"2
