No matter how big you get the speaker, its not going to take the place of a sub(s).

With the QSC, it does room correction as well as does equilibration for 80 hz and below.

When I used MRC on the 861, I was not able to achieve the sound quality I was able to get with the QSC.

By the way, If you ever get a chance to look into the control room of a movie theater, you will see QSC.

I'm well aware of what you're talking about. If it were so simple your 861v6 would have worked just fine.

I have no urge to add more bass. It's not a large room. Only thing I may consider is an LFE sub for more accurate bass.

You have a "QSC System" (as far as I'm concerned) just like the movie theaters.

I also understand perfectly why MRC would fall flat on it's face. You tried to make it do what it was never designed to do.

You talk about "luck" I think it's just plain luck the ADA is working better for you.

If you think listening to music is fun, try learning an instrument.
