Benefits of a Shallower Rack

I’ve got a relatively small listening space to work with. Also limited adjustment toward the center of the room as I’m not the only one using the space (yet it is largely dedicated to the stereo). Although I’ve managed to arrange things so my speakers are at least three feet from the sidewalls, I really can’t go past 19” from the front wall - measured from the rear of the speakers. Being that the room is only 11x12’, I’ve noticed that even minor adjustments and wall treatments can render serious results. Even moving my Pangea (a cheap and monolithic four tier) audio stand slightly from left to right when experimenting with sub placement can majorly affect the center image.

So I wanted to ask here how many of you may have gone to a wider/lower rack to good effect? Or did it present yet another problem that became more of a trade off than a benefit? The idea being that I would remove some spurious reflections via bringing my gear closer to the floor and out from between the immediate field between the speakers.

Ultimately looking to diy a decent wood rack that would sit far lower than what I’m currently using.

Thanks to everyone in advance!
