Each reflection of sound within a room can be modeled using the equation:
S' = A*S
where S is the input sound, A is a frequency response representing the attenuation caused by energy loss during reflection, and S' is the output sound. This is a LINEAR system (in most cases), so if we make everything twice as loud:
S'' = A*(2*S) = 2*A*S = 2*S'
we get double the output volume. The sound that you hear in a room is caused by millions of these interactions summed together. The other major factor in modeling room acoustics is the distance attenuation that sound experiences as it travels through air:
S' = 1/(1+D^2)*S
This is still a linear system and will behave accordingly if you increase the input volume. However, you can lessen the effects of room acoustics by increasing the size of the room: increasing the average D in the previous equation will net a lower ratio of room to direct sound. It will also push room modes to lower frequencies. A room that is bigger than around 55 feet in all directions will have all room modes below 20Hz.
Oh, and if we're going to play that game, this is a mix I did last night in my untreated room:
