It means, that in accordance to REW ideology you may turn your sub by 180 degrees from main angle position (face to listener). See mark 'invert' when simulate by control interface of code. At inverse position distance between sub PP (cone) and wall equals 0.

subwoofer is facing my seat. so 0?

Look at this picture, please. I've tried to show how to evaluate distances for front wall.

thanks a ton i would go with 30 cms but still i need that calculation again like my pb 2000 pro depth is 23 inches so what would you do?

You have to shift your sub forward from front wall to 11 inches to get 23" from front wall.

its not inverted it is facing my listening position now how do u consider it from wall if back of subwoofer is touching the wall. means 0 inches

To achieve an according between measurements and calculations you, the first, have to determine the Power Point for your sub (with relating to LF range, because your sub may have more, than one PP), i.e. to find the coordinates set of PP inside your sub, the second, place your sub the same position at calculations like for measurements and to compare results. To realize the first step, it's strongly recommended to close the aperture of the phase invertor by soft material due to measurements, because the REW simulation method doesn't use such a feature. Only in case you subject to these conditions, hope to use REW correctly. It's important to achieve a match between calculation and measurement results within at least 75%.
