That is definitely not going to work. WIth that box design your box is tuned to about 77Hz and will sound like complete crap.

huh? how did you get a tuning when he just posted external dimensions?

OP, you dont want to tune a DD woofer that low. stick with around like 35-37hz.

Can you explain how you got that with just his max dimensions?

Welcome to the forums.Here is a suggestion for a box:

Enclosure Specifications:

Fb = 37 Hz

Vb = 0.88 ft^3

External Height = 12 in

External Width = 20 in

External Depth = 14 in

Port Width = 1 5/8 in

Cut Sheet List:

* All Dimensions in Inches.

* Wood Thickness is 3/4 for all Parts.

External Enclosure Parts:

Front = 17 5/8 x 10 1/2

Back = 20 x 10 1/2

Left & Right Sides:

Side 1 = 12 1/2 x 10 1/2

Side 2 = 13 1/4 x 10 1/2

Top & Bottom = 20 x 14

L Port Internal Assembly Parts:

Front to Back = 10 7/8 x 10 1/2

Extension = 14 1/2 x 10 1/2

Extension 2 = 3 1/16 x 10 1/2

Let me know any questions.

Its a simple algebra equation.
