15" subwoofer build

I am planning to build a pair of sealed subs using the new sql-15 driver.

With the help of a friend I was able to draw up a box.



These boxes will be CNCed some day in january and before that I thought id post and ask if anyone could see problems with the design.
Mainly if the bracing is adequate or not. As you can see bracing has been designed for a easy build process.

I would add L-shaped bracing center-to-sides from the top and bottom as well.

Sub builds: Yet another Infinity 1260 build | Twins! | Modified V.B.S.S. build | UM12-22 builds | AV stand and sealed UM18s

Speaker builds: DIYSG HTM-10 build | DIYSG Volt-6 build | DIYSG Fusion-8 builds

I'd add a plane between baffle and rear and one between the sides vertically to tie all the panels together.

Thanks for the replies guys,
would it be possible to use a couple dowels to do the additional reinforcing?
Are they hard to work with?

I used the concepts outlined in the NCM Cabinet Handbook.

A bit more bracing than most but rock solid.
