Baffle step correction isn't wanted or needed for these speakers. They're designed for uniform power response over a wide area, and baffle step is really specific to on-axis response. Even if considering just the forward axis, speakers with baffles smaller than about 18" might benefit from BSC, but I think larger speakers make it inappropriate. Any baffle step would be near the room's Schroeder frequency, so baffle step has little meaning. Sound progagation is transitioning from modal to reverberent in this range and the relatively small EQ provided by a BSC circuit would be overwhelmed by room influence.
What I would suggest is setting up the speakers as shown in the links below. If you add subwoofers, you'll not only increase bass extension but also smooth room modes. That's the best way to provide smooth balanced response in the modal region.
