So with that in mind, we know that the first reflection off the front wall is going to be a low frequency bounce.
Not really. You can measure the influence of placing an absorber behind the monitors at least up to 500 Hz, I tried so, in several rooms with different speakers (Adam A7, Neumann 310, Dynaudio BM6A, Genelec 8050 to name a few). If it was only up to 150 Hz, no problem, the discussion here wouldn't even exist. I did so using Basotect with a width of 15 cm and about 10-20 cm air gap. cheers
