The model would show more peaks in the response if he had calculated response radiating into 4π or 2π space. But each horn mirrors the other and they are very near the floor and other room boundaries. With bass wavelengths being so long, and the room comparitively small, I think using a highly constrained space in the model is probably pretty accurate. For example, the wavelength of 30Hz is nearly 40 feet long, so boundaries closer than about 10 feet are launch boundaries. It might actually be more accurate to see it as more tightly constrained than π/2.
