Alright so ive been messing around with RE Enclosure Calculator...
RE Enclosure Calculator (http://www.reaudio.com/speaker_box/LPort_Box_Calc.html)
The Red is my inputs to hopefully make it faster for anyone who can help off that site or just general knowledge i guess.
Box width - 60"
Box height - 24"
Box top depth - 4"
Box bottom depth - 10"
Wood thickness - 3/4"
Square port height - 22.5"
Square port width - 1.5"
Square port length #1 - 4.75"
square port length #2 - 14"
Total port length - 21.75"
Square port diameter - 6.55529058355247
Square port area - 33.75
Square port volume internal - 734.0625
Square port volume displaced - 747.5625
Box Volume(Ft3) - 3.757
Box Volume(In3) - 6491.8125
Tuned Frequency(Fb) - 30.191278937147

This is Sundowns Req's
Mounting Depth = 6.5"
Cut-Out = 10 15/16"
Displacement = 0.14 ft^3
Overall OD with Gasket = 12.5"

Enclosure Suggestions:

1.75 ft^3 ported tuned to 30 Hz -- F3 of 26 Hz
* Tune higher and use a smaller box for more SPL oriented setup (Use 1 - 1.5 cubes)
* Enclosure can be as big as 2.25 ft^3 with lower power levels

1.00 ft^3 sealed -- F3 of 44 Hz
* For SQ and space limited applications

Just looking at the volume and tuning I would say yes.

Your port is Fvcked. Do you need it to be slanted?

It could be closer to 4 cuft.
You may have to mount them near the bottom depth wise.
