Interesting.
Here's some simple math :
speed of sound / ceiling height = frequency
1125 ft/s divided by 9.58 ft = 117.4 hz
You're vertically about in the middle of the room so you're right in the center
of a 117 hz wave which is null.
The room's resonant frequency (mode), vertically, is half that at about 59 hz.
I think you'll have to do something either on the ceiling or on the floor.
