Depending on your equipment there could be spikes and nulls all over the place, so I’d look at multiple subs, room correction and listening position first.
If it’s a dedicated listening room and aesthetics aren’t an issue you could experiment with resonators.
If memory serves correctly, resonators perform better when ‘floating’. Suspended by cables.
A few control rooms I’ve been in had huge resonators installed in a notched out section of ceiling. Without doing any calcs, the ones you specify sound small, particularly in thickness.
If you’re planning on installing behind the listening position they’re also going to affect the upper mids and highs.
If you’re committed then I suppose the best way to move forward would be to get some dense foam and experiment with positioning before building anything permanent.
I’m no expert, but I did a module in acoustics when I studied sound engineering.
Bass management is the hardest part of acoustics.
