Ok so I emailed KICKER again with my concerns and this was the reply:
The tuning of 12's between 37 and 40 is a great range. Most music has
the main amount of bass between 40 and 50 hertz. The woofers in those
enclosures will still play down to 25 hertz and up to 100 hertz. Our
favorite box for the CVR12's is the street bass box. We still recommend you
build each chamber (the woofers should be in separate chambers) to 2.82
cubic feet with a port opening of 33 square inches and a port length of
16.5" for each chamber.
