Best Methods For Internal Bracing ? My Box Pic Inside

[Joker]

Box is 6ft3 net * 32hz , 77.5sq inch port for a loaded 18" btl , sub up / port back , power is going to be a sundown 3500d * 1ohm .

I was thinking of furthering the 45's to the top and bottom running horizontially{ very small peices not huge 45's like you see ) , not in the port though . More to get rid of as many 90 degree angles as I can . Do you guys think I should make the 45 on the port side bigger/wider ?

Also thinking of putting a peice horizontally of sanded and rounded edged 3/4" mdf peice about 4" in length inside the middle of the 5" width port . Thought of making an extended peice that continues horizontially almost to the 45 since the area is wide open there .

The top I have 2 peices cut so it is getting double baffled , sub will mount on second .

Thinking 1/2" All thread making almost a cross inside the box mounted as close to middle as possible dodging the subs massive magnet . Maybe 2 peices of wooden dowel rod's running vertically on side of sub edge to help support the middle baffle area . I am going to try to mount the sub as far away from the internal port opening as possible .

Here's some picture's of my box so far .

Only my 2nd box I designed and built myself and I dont have a table saw or router , so take it easy .

2x4s is wat i use for bracing. always works for me

I didn't want to use 2x4 , they eat to much space and block the airflow. You have a wall , how about for just the common box .

allthread or dowel rods, like shown in the last 2 boxes. I prefer all thread, but dowels are cheaper
