in wall speaker backing?

I have purchased a pair of 265 RT speakers to use in my basement for a small movie setup. These will be front left and right and no center (phantom center).
I will also be using a subwoofer.

What I read is that the speakers will sound better by not building a backing enclosure, just leave them open in the stud wall. It also said if you must build an enclosure, it should be 1.2 cubic feet including the speaker.

I am asking which way to go as the wall I am using is not a standard wall. This wall is in the middle of the basement, about 7.25 feet wide and 9inches deep. The wall actually has two stud frames inside, each made of 2x4 and neither touches the other, there is almost 2 inches of space between them. No insulation, just a few fireblocks. Then there is drywall on both faces of the wall. Both speakers will be in this wall as far to the edges as possible.

For such a large space, should I enclose the speakers? And if I should enclose them, why does polk recommend such a small enclosure if they are designed to be used infinite baffle or free air?

THank you

    Infinite baffle works by simply separating the front and back wave. You shouldn't have any issues.
