My Rel Storm 3 has its crossover set at about 28 hertz, and it sits in a corner. I am generally not finding that the deep bass localized to that corner. Instead, it seems to emanate from between the mains, possibly sometimes just off the midline towards the sub-bass unit, but usually not.
On the other hand, I had a passive subwoofer in the back of my van, and it was clearly localizable to.....the back of the van. I don't know what frequency the crossover was set at on the amp feeding the subwoofer in the van, however.
