Hi Casey01 and all,

Interesting discussion, but the applications are rather different. For performers in a band on a stage, you certainly do not want the mechanical vibrations in the floor from bass cabinets to travel to floor-stand supported microphones used for other instruments or vocals.

In a domestic hi-fi playback, the situation is quite different. There is a persuasive argument that floor-borne deep bass vibration is part of the experience, if you are trying to replicate live concerts. The vibration of a church pew and floor in a pipe-organ recital is certainly part of "hearing" ultra-deep pedal notes, and you can certainly sense some of the vibration of concert-hall orchestral bass drum reverberating through halls in good concert halls or small clubs for jazz.

Some of the worst concert hall acoustics of halls built in the 1960s and '70s partly resulted from concrete floors that didn't conduct any sense of mechanical feedback of orchestral power. Those halls are often acoustically refurbished by putting in wooden floors over the concrete, so audience members will get some sensory mechancial feedback.
