What is this 50%, 75%?
So at the main listening position if it's 100dB, it will be 50dB 1ft further from that, and 25dB a few feet further?
Where are you getting your "physics"?
And how do you apply your so-called "physics" to corner placement where a sub can be 8-15' away?
I suggest you at least TRY a subwoofer, not even the MBM, nearfield behind your couch before you make assumptions. Dr. Hsu has always been an advocate of nearfield placement. I assume he knows what he's talking about. Mid-bass impact is greater at nearfield as well, whether it be to the side or behind the listening position. Which is the concept behind the MBM.
And I myself have tried a subwoofer behind the couch with great results (aside from integration with the mains, which was due to bad speakers and a fixed 100hz crossover at the time - I have since upgraded all of my equipment). The SPL wasn't any different across the three seats as it is when the sub is put in the corner.
With the sub in the corner, I have measured the response in the three seating positions on my couch. Bass traps help keep it more uniform, but there is still a big difference moving to either side of the center position.
