Robo (what's your name?),I'm not sure what I'm supposed to be seeing there. I can't discern any difference between the Before and After graphs other than it looks like the volume control was turned down 6 dB. Everything else - the response shape, the ringing decay times, etc is exactly the same. Usually, even minimally effective acoustic treatment has at least some affect at the higher bass frequencies. But even at the 200 Hz right side edge the two peak shapes are identical.
What am I missing?
For reference, the graph pair below shows a typical domestic size room with and without bass traps.
