You'll always need to short the positive/negative leads of the pair which is not playing.
From my own experience, even if both pairs are 5 meters apart from each other at each end of the room, the un-shorted pair not playing will cause the pair that is playing to have smaller, collapsed soundstage.
Being connected to an amplifier doesn't count.
You will need to remove the speaker cable from the speakers, and then short the positive and negative terminals with a short length of cable.

Wow, I've heard of "out there" but this is the most "out there" I've ever read.
You just won the Darwin award.
Do a search for Jerome's posts in the archives. This is pretty much par for the course. A very advanced thinker!
*LMAO* Thanks for the chuckle. :)
Sorry but at eight feet magnet strength, (unless a Goto or TAD 4001 type) is a non-issue.
But if the (non-playing) speaker is ported, better to just plug the port. If not the speaker will bounce at driver/enclosure resonant frequency. Putting a resistor across the terminals of a speaker, will change its Q of tunning frequency, but not eliminate it in same way as plugging the port.
If sealed, minor benefits at best.
Sorry, I'm not sure I understand how to short the speaker terminals. Would you mind explaining further? Thanks.
Never, ever, never short the output of an amp.
Shorting an "unused" speaker is done by bridging the positive to the negative terminals with a short piece of wire. Similar concept to biwire adapters that come with speakers to bridge positive to positive / negative to negative except you're going positive to negative which stops the voice coils from reacting to sound pressure from other speakers that are playing.

Do not do this with an active pair connected to an amp!
I assume no liability if someone does not follow directions.
And yes, I've had multiple speakers in rotation in one system all in one room. I've also had two systems in one room like you asked about but I had the luxury of using both short wall and long wall simultaneously. One solid state and one tubed. I did have to move speakers that where in close proximity depending on which system was in use.
...and tune the room with resistors!
