So I have a room shaped a little like this

The floor plane is 6x7m
Ceiling plane is 2.4m h

Continuously variable waveguide(r) QRD (prime 7) that is based on research by UTS (Sydney) and the bandwidth advantages to be used >100hz

How is it calculated?

Additionally I am thinking of using infinite baffle subwoofer in the ceiling/centre as mentioned in another post…but here is a pic of intended install on a cement face plinth, elastomeric decouple to structure; hence my wanting to model/precalc a little to get an idea of possibilities.
