First off, thanks for all the responses, suggestions and advice.
I really like the way the bass sounds with the two subs as opposed to just one.
I also like how the bass sounds with the subs mid-way up the side walls as opposed to the corner placement. It feels more balanced, louder and less strained(?). So, yes to rc22 . I think the tonal balance is better with the subs out of the corners. And, as I said, although I’m actually sitting closer to the subs I’m not aware of them at all. I had to make sure they were "on" and working.
I was just more concerned with the perceived drop in overall volume since the relocation of the subs.
I’m hoping that my hearing hasn’t all of a sudden just dropped off and I lucked into" smoothed out the bass so it is less prominent and more blended. It only sounds lower because it is smoother." as kota 1 suggested.
I’m also going to try what musicaddict suggested.
Looking forward to further experimenting today.
rc22, I like your analogy of driving 85 in a smooth quiet car as opposed to a noisy one when I went from my old pickup to a Lexus ES350. I had to watch my speed as it didn’t feel like I was going fast. In the truck, I knew how fast I was going without looking at the speedometer.
