But I do see your point.
You are flat out wrong. I hate to be blunt, but your argument is so false that you have no idea. Let me try yet one more attempt to help you to understand. I don't blame you, it is our fault for not explaining it in a clear way for you.
I've already said this before, but let me break it down a little better.
I have 2 rows of 4 seats. Lets just say seats 1-8 for simplicity.
I can sit in my seat (seat 3) and the bass sounds great. It should, because that is where I sit so I've taken steps to ensure that. The bass sounds equally good in seat #2 right next to it. However, seats 1, 4, 5, 8 (outside of the two rows) have louder, more "pronounced" bass. That is due to the long frequency waves of the bass. In the seats 6 & 7 in the middle of the back row, there is almost no bass to be heard. That is because the sound waves dip down right at those locations, just like they are higher where the bass is "too loud".
Adding a second subwoofer adds more sound wave sources, meaning that the sound waves overlap each other and the 2nd sub starts to add bass to where there wasn't enough (its peaks fall where the nulls of the other sub do) and its nulls fall where the first sub's peaks are. These help to give the same bass/LFE effect levels at each seat.
Now, can I hear that I have, as you call it, "stereo" subwoofers in my seat? Heck no. But I can now go to each of the seats and have a more consistent bass/LFE experience due to the second sub. Hopefully that helps explain it a little.
Yes, you can crank things more, but again, that isn't the point. No, you can't hear the difference between a single and "stereo" subwoofers like you said. The idea is to make each listing position have the same bass experience and using the multiple subs help to reduce the peaks, increase from the nulls, and make the bass sound great in the whole room.
