I found that to get results that are even remotely close to what they used to be, I've had to go through loads of settings and controls to try to get it back to where it was before. Before, I had extreme low end impact (10-30hz range used to be much more audible). Although I have much more headroom and a much more even frequency response, I think that the corner with the much improved settings and modifications will yield even lower frequency response and possibly better frequency response in the corner. I will try this. Will I need to make any settings modifications like phase if I move the sub to the corner?
You will definitely need to adjust each sub separately. If you have an SPL meter, adjust the amp level of each sub first by turning off the other one so that each subwoofer gives you approximately the same level. You don't want one subwoofer to overpower the other one.

Next, you need to adjust the phase of either subwoofer to get the maximum output at your listening pposition.

After that, run Audyssey for multiple positions and tweak a little with an SPL meter.
