Both the four Pi and the seven Pi loudspeakers are slightly overdamped, giving gradual rolloff at LF. In freespace, output at 50Hz is 6dB less than 100Hz. But small to medium sized rooms tend to boost bass. This is even more pronounced when the speaker is placed in a corner. Every room is different, so you cannot say exactly how much boost you'll get but in general, this response curve ensures smoother bass indoors than a max flat alignment.
