Sub Box Design

Recommended Posts

Can someone make me a design for 2 12" Alpine Type R subwoofers. I need it to be 4 cubes, and want to have it tuned to 33hz. My trunk dimensions are 40 W, 21.5 H and 23 D. Any help or suggestions would be appreciated too.

Here is a suggestion:

Enclosure Specifications:

Fb = 33 Hz

Vb = 4 ft^3

External Height = 16 in

External Width = 37 in

External Depth = 19.5 in

Port Width = 3 3/4 in

Cut Sheet List:

* All Dimensions in Inches.

* Wood Thickness is 3/4 for all Parts.

External Enclosure Parts:

2x Front = 16 5/8 x 14 1/2

Back = 37 x 14 1/2

Left & Right Sides: 18 x 14 1/2

Top & Bottom = 37 x 19 1/2

Shared Port Internal Assembly Parts:

2 x Front to Back = 16 1/8 x 14 1/2

2 x Extension = 4 9/16 x 14 1/2

Assembly guide (generic dimensions):

- The 45s if you want to do them are 2 1/2" wide except the ones inside the port, if you want to do those let me know.

- All trunk boxes built outside the car need to fit in their way in not just have the right dimensions.

- The port needs 3 3/4" of free airspace in front of it for proper operation.

- Setting your amp's subsonic filter to 28Hz is suggested.

Would be louder to have them firing backwards.
