Al, just curious if you ever tried your subwoofers pulled out into the room, out by the mains?
I'm doing so with mine right now and am actually getting slightly better results, though I know all rooms and systems react totally different.
Thanks for reminding me, Chops. That was a thing that I wanted to try at some point, but then the pandemic hit and I didn't want to go to Home Depot to buy some concrete plates (like I have under my monitors) to put the subs on next to my speakers. However, coherence of bass timing is not an issue in my system (even though theoretically it might), so I wanted to do this out of curiosity rather than need. Now that the pandemic is under control in Massachusetts I might make the trip to Home Depot after all...
