I followed a 1:4 Sealed to ported ratio and it worked out well.

Custom Mild steel Bracing for the enclosure

Forgot to Mention , The enclosure was fibreglassed and resin from the inside... Pics

But as i mentioned before since the plan got changed in the end, i Had to rip apart the enclosure and make changes in the Subwoofer baffle to accommodate 4 12's instead of 2 15's . Also had to reduce the sealed chamber volume from 5.6 Cu ft to 4 Cu ft.... Here are some pics

New Baffle added and notice extra 2 layers of 1" MDF used in the right to reduce the total volume of the sealed chamber

Looks awesome man! Keep staring at the pic but is that brace a solid piece? Or is it 2 pieces?

It was in 2 pieces welded together..

That MDF is 2 pieces of 1" MDF sandwiched together using adhesive and then resined
