Mayor: Glade you figured out the calibration. I usually view the graphs at 1/12 octave. I'm told your ear doesn't hear fast transient spikes or ringing below 100 Hz. I would focus on extended (time domain) peaks and valleys. DSP can cut down those peaks in the low frequencies but there can be trade offs. I chose not to use DSP but that was my preference. I think you would notice an improvement if you could correct the valleys.
The only treatment I have is a wall diffuser. (Arqen lean diffuser). So I can't recommend any treatment for bass mgt. although at those frequencies it will be thick.
