I did not understand this to be a air vibration transmission back into the signal. Think about where bass is strongest. Usually at the back wall and corners. Sure you could get some, especially through vinyl. My understanding is you have a large reflection in between your speakers messing with imaging and maybe smearing the timing.
My gear is between my equipment but I keep my rack sides open, not solid.
Friends of mine keep the amps real low to the ground, then a slender open rack between and as far back as possible.
I have other friend saying 30 foot single ended interconnects may shave a little top end, but the staging and clarity outweigh the loss. As long as you don't get RF interference. If the long interconnect picks up radio, well? ????
