Well I have made quite a bit of headway. Surprisingly.
As it turns out, having the sub on the couch (for listening position) is not equal to having the sub position on the floor in the listening position. Having done the sub-crawl this way, was very different.
Long story short, I found a position that actually blends quite well. It was about three feet out from the corner, and about a foot out from the wall. The LFE signals are the best sounding they've ever been. Though, I am still thinking about putting the other sub under the couch. We'll see.
