It would appear that the bass in the 40 - 50hz region is some 25dB louder than the rest of the frequency range, making bass in this region appear to be over 4 times louder. (an increase of 10 dB sounds twice loud to the human ear) Can this be true? It does not actually sound like the low bass is 4 times louder than it should be?
I wondered about that when you posted your results. Was the microphone close to a rear wall, by any chance? I understand that would tend to boost bass frequencies (there's a helpful article about this effect here).
Anyway, I think the key words in your question are "louder than it should be". I suppose it depends what you regard as the expected loudness - what you're already used to, or flat response, or something else? For example, when I installed my Anti-Mode, the instructions (yes, I actually read them!) were at pains to point out that having a flat in-room bass response often sounds a bit "bass light" since people are generally used to hearing bass augmented by room effects. After a while one's ears and/or brain do tend to recalibrate a bit so the flatter response now sounds "normal" to me.
I hope you have a fun week-end - and look forward to hearing how you get on...
