i'm about to start a build for 2 dd9512's....that will be powered by a sundown 3500 in a scion xb....before i begin the build i would like for yall to tell me if you see anything wrong with this design...its a slot port but i'm used to using L-shaped ports and this doesnt have the L-shape so i'm not sure if it will have the same output....but here's the design it's 5.3cubes after all displacements, at 36.5hz, with 18sq" of port area per cube

Looks good.

In my experience you are better off without needing to L the port off to obtain port length anyway..

Makes no difference, I'm assuming you're tuned in the upper 30s/low 40s so the L shaped port is not needed to achieve your desired tuning.

yeah its tuned right around 36-37hz
