Aero Port Qustion

[ShortWide1994]

I'm building a box for a DD9512 in a 2000 Z/28 Camaro and cant come up with a good slot port design. The dimensions are 13 x 14 x 34 and comes out to be around 2.7 cubes. So what aero port can be used to tune it around 34 hz? Thanks for any input

Here is a slot ported design that will tune about 34Hz on your dims port and subs are in the same face:

Enclosure Specifications:

Fb = 34,023 Hz

Vb = 1,929 ft^3

Subwoofer Mounting = Front Mounted

External Height = 13 in

External Width = 34 in

External Depth = 14 in

Port Width = 2 1/2 in

Cut List:

* All Dimensions in Inches.

* Wood Thickness is 3/4 for all Parts.

External Enclosure Parts:

Front & Back = 34 x 13

Left & Right Sides = 12 1/2 x 11 1/2

Top & Bottom = 34 x 12 1/2

L Port Internal Assembly Parts:

Front to Back = 10 x 11 1/2

Extension = 15 x 11 1/2

Let me know if you have any comments.

Forgot to mention, driver displacement used is 0.18 cubic feet.

The problem with that is that the front of the box has to be angled to clear the rear wheel wells, so there really is no way to put slot port.

I see but dims for an angled box should include H,W,D1,D2

The lenght of an aero can be calculated whith this:

But the minimum port area has to be observed.
