Ok I worked out my box dimensions. Please verify they are correct, so I can get started.
Resonant Engineering XXX 12" Sub.
Wood 0.75 or 3/4" MDF.
Sealed - 16w-13.5d-13.5h = 1.21 After displacement 1.02ft^3
Ported - 35.5w-15d-15h = 3.59 After displacement 2.49ft^3
Slot Port 13.5h-2.5w-36d = 0.91
Tuned to 30.47 hz
Can any one verify these dimensions for me to make sure I got them accurate.
Measure twice cut once as it goes.
