Jerry,
Now it gets interesting

To manually adjust, simply open mconfig room correction tab - open your profile and for each speaker ADD new filters focussing around those bass peaks - you'll probably want two filters each centred on the peaks you can see - you will see a box appear which you can drag to adjust the width and amplitude of the adjustment. You can even make adjustments while displaying the low frequency curves - just open the profile twice - then you can see in real time what your adjustments do to the curves. But note, that the adjustments you see are unlikely to match precisely what you really hear, the only way to be certain is to use a real time analyser such as TruRTA. But for now I'd aim to bring the lumps down to within 5dB of the average curve - a small lump in the bass can actually be a good thing to most ears...
Have fun!
