Box design help

[NLMax]

I need help to design a box because i know nothing about "Torres Box Tuning Calculator"

And it's all pretty difficult for me because English is not my best language.

Max dimensions are 60H x 75W x 45D. all in centimeters.

Subwoofer: Sundown SA-15

amplifier: Sundown SAZ-2000D

So, Who can help me to design a box?

Kind of difficult to come up with a spec in metric units, also that is a powerful amp, I gave you tight volume on the box to help protect the sub but you should engage the subsonic filter of the amp and set it to around 30Hz:

Enclosure Specifications:

Fb = 35.017 Hz

Vb = 3 ft^3

External Height = 45 cm

External Width = 69 cm

External Depth = 45 cm

Port Width = 7 cm

Cut Sheet List:

* All Dimensions in Centimeters.

* Wood Thickness is 18mm for all Parts.

External Enclosure Parts:

Front & Back = 69 x 45

Left & Right Sides = 41.45 x 41.45

Top & Bottom = 69 x 41.45

L Port Internal Assembly Parts:

Front to Back = 34.45 x 41.45

Extension = 21.15 x 41.45

This is how parts assemble:

Wood thickness is set to the nearest metric equivalent of 3/4" normally used in boxes which is 18 mm.

Let me know if you can't find 18mm wood, if you have the D4 version also let me know.
