Speaker Level adjustment shoud compensate.
You room is fairly long at 22.6 feet. You should be able to receive the sound fine after level calibration. I would asthetically , as possible, place the speakers then adjust the sound levels, first automatically with a microphone and then with your own ear preference or with an SLM.
You need to figure out where you are cofortable with your sub and adjust the levels accordingly.
Have you determined what speakers you will be using? What is your speaker budget?
