It's not the dipole operation of the sub itself I'm concerned with losing---of course it will retain that no matter it's orientation. However, because a Dipole sub exhibits a null to each side, it doesn't excite room modes from both the length and width of the room that an omnipole does, but rather only modes produced by the dimension of the room the Dipole sub is firing towards (front and back). That is a distinct benefit of Dipole operation, one very valued by Dipole sub owners such as myself. If I rotate the H-frames away from being parallel to the walls they are near, the side of the subs (and therefore the nulls) will no longer be facing the side walls, and the subs will then be very able to excite the modes of both dimensions of the room's floor plan, losing the Dipole null benefit. Or am I mistaken?
