This was suppose to be a raw box because it's a temp setup, but I decided to cover it anyway. The subs were so cheap I wanted to experiment with them. This box is 12cu ft tuned around 30hz after all displacements. It has 6 4" pvc ports. This is a simple build with no fancy bracing, but my box does not flex. This box has been installed for about 3 months so far. Subs are being pushed by a Brz2400.1d.
Ports are held in by Liquid Nails, no screws
