I had help from acoustic frontiers in sub/speaker relocation to smooth out bass. I have at least a hundred REW measurement from this misadventure. The subs ended up near opposite corners of the room, which flattened all but the 60Hz. Elevating them half way up the wall helped partially, and the crossover eliminated it. With the fathoms, I now have a 20 Hz issue, below what DARO controls. I pulled one sub out in the room as far as resonable to flatten it, but created a massive 34Hz issue that daro amazingly corrected. I did waterfall overlay between the two radically different positions, and there was not much difference even in decay time. I could not really hear a difference either. I may try moving one sub to the corner, so the pair are symmetric to see what happens.
Like you suggest, I also EQ’d it then adjusted levels, which is easy. The LF trim control’s bandwidth is too broad, so of course volume has to be adjusted. Unfortunately I do not know how to use stereo with separate phase controls and use DARO at the same time. Are you using master/salve configuration?
