Geoffgarcia,
The Rogue66 inverts phase. So, this is 1 phase inversion.
Does the Rogue 88 invert phase?
If yes, this is the 2nd phase inversion. Hence, no need to cross speaker connections as 2 phase inversions of 180 degree brings you to 360 degrees, which is the same as zero phase inversion.
If the Rogue88 does *not* invert phase, then you have to cross speaker connections.
