In his video discussion of Perlisten in-wall speakers, Mathew Poes mentions that the Perlisten in-wall speakers have a different crossover design in part because there is no baffle step when the in-wall speakers are installed in-wall.
Perlisten sells on-wall frame kits:

The question is how much of a baffle step does the on wall frame kit create? In other words, should the crossovers be tweaked to account for the on-wall mount vs in-wall mount?
The reason I ask is that I'm considering replacing the in-wall speakers in my living room system:

The upright structures on either side of the fireplace and TV are about 18 inches wide, which creates a baffle step, at least to some extent.
The upright structures have a layer of drywall on several layers of plywood (probably 4 inches of plywood). Thus, the upright structures appear to be structural and I'm reluctant to cut large openings for large in-wall speakers (e.g. Perlisten S7i-LR).
On-walls will not look great, but I can live with it if the sound is good enough.
Worst case scenario I can cut openings and reinforce the upright structures, so in-walls are not out of the question.
Personally, I think a pair of Perlisten S7t towers look great in front of the upright structures, but I doubt I can talk the wife into it (that was tongue-in-cheek, I'm not wild about the appearance of towers in this location)
And, if anyone is wondering, I've tested the temperature in the cabinet by the TV when using the fireplace and it's never gone above 93 degrees. Not ideal, but so far all of my TVs have become obsolete before they failed.
