The Ultimate Subwoofer (BD-Design)

what does high SPL generated in a small room from all of those woofers do
to another speaker cabinet?

I have no idea and this is not the idea behind the subwoofer - just generating high SPL's...

The idea is to genreate the needed SPL asked with normal playback levels but then without any distortion (no moving diaphragms as a result when using many drivers giving a huge total diaphragm surface - Sd will be 1,728m^2!!)

Am I right in thinking it will "pump" the Swing and force the driver to
move from the air pressure and cause distortion? It would be interesting
to put an oscilloscope on your main speakers in the room and see what
microphone effects can be measured.

It will not affect the Swings performance when the sub is integrated and EQ-ed properly (phase, time and SPL). The sub will do what the Swings don't do... and work together in their overlapping frequency range.

Using two of these in a room you could make some spooky party tricks with
a balloon sitting on the floor. Expand balloon, contract balloon, move a
little bit to the left, expand, contract, move a little to the left.

That balloon will surely be presurised and moved around in the room (you won't need a balloon to visualize things, you will sense this with your body).
