HOW TO POSITION 2 PAIRS OF SPEAKER FOR ALTERNATE LISTENING

According to Jim smith, you never want more than 1 pair of speakers in a room. The driven pair will start to move the cones of the standby pair

@rbstehno  +1  The effect will be a slight "smearing" of the sound of the speakers that are playing.

@rbstehno @hifiman5 Have you heard an audible impact?  It makes sense and functioning as resonators, but many showrooms have multiple sets.  I think the effect has to be slight...at least I hope so.

I have seen the mids/woofers moving a little so I just moved them out. I can’t remember if I heard a difference or not, it’s been years

The biggest problem is that you may want each pair of speakers in the same location in the room when being listened to. Better to put the unused pair in another location in the house. If the unused pair must be in the room, short the speakers by running jumpers from positive to negative terminals, and cover them with a blanket.
