Can someone please double check my box design for RE SX 18

This is my first box so I have no idea what I'm doing!

7.573 cubes @ 34.21Hz

I may reduce the port width from 8 inches to 6 inches which will bring the box to 8.574 cubes @ 28.54Hz. Input?

(Will change a little with sub displacement)

Bottom: 48" x 22"

Top: 48" x 22"

Left Side: 21.25" x 20.5"

Right Side: 20.5" x 20.5"

Back: 48" x 20.5"

Front: 41.25" x 20.5"

Port L1: 14.5" x 20.5"

Port L2: 13.25" x 20.5"

What would sound the best? Any suggestions?

I haven't doudle checked your math, but the indicated volume and tuning will be fine. Sub will be pretty efficient in a box that size, too...

Thanks for the input! I just wasn't sure if there was a rule of thumb as to how long you should try to make the port walls in a L shaped box.
