15" sub with port compression vs 12" without compression

[Joe X]

Here's a couple more normal ported options for you to consider, the second one fully complies with your available space but if possible I would do the first one. Figures are just assembly guides.

 

Enclosure Specifications:

Fb = 34 Hz
Vb = 3.5 ft^3

External Height = 19.625 in
External Width = 49.625 in
External Depth = 10.5 in

Port Width = 2 3/4 in

Cut Sheet List:

* All Dimensions in Inches.
* Wood Thickness is  3/4 for all Parts.

External Enclosure Parts:

Front = 46 1/8 x 18 1/8
Back = 49 5/8 x 18 1/8

Left & Right Sides:
Side 1 = 9 x 18 1/8
Side 2 = 9 3/4 x 18 1/8

Top & Bottom = 49 5/8 x 10 1/2

L Port Internal Assembly Parts:

Front to Back = 6 1/4 x 18 1/8
Extension = 15 3/4 x 18 1/8

 

Enclosure Specifications:

Fb = 34 Hz
Vb = 3.2 ft^3

External Height = 19.5 in
External Width = 49.5 in
External Depth = 10 in

Port Width = 2 5/8 in

Cut Sheet List:

* All Dimensions in Inches.
* Wood Thickness is  3/4 for all Parts.

External Enclosure Parts:

Front = 46 1/8 x 18
Back = 49 1/2 x 18

Left & Right Sides:
Side 1 = 8 1/2 x 18
Side 2 = 9 1/4 x 18

Top & Bottom = 49 1/2 x 10

L Port Internal Assembly Parts:

Front to Back = 5 7/8 x 18
Extension = 17 x 18

Triticum and Joe X,

 

You guys have given me some great options to consider. I was all set on the PR, but now might try one of Joe X's designs. Either way you guys have given me more information than I had before, thank you.
