Could you imagine a scenario where isolating loudspeakers could be really beneficial to SQ.
Say a suspended floor which audibly resonates because of the structural borne vibration propagated from the loudspeakers.
How would the airborne vibration compare to the structural , any links to research would be useful.
A few years back a very nice chap from Speirs&Robertson came to measure my ( suspended) floor with a three plane accelerometer, even with the speakers playing bass heavy music, very loudly there wasn’t that much vibration .
Interested as always to hear your thoughts.

Concrete slab floors and no seismic activity here..

You want a sandbox for isolation?

My whole house sits on one.

My third floor music room really shakes around 31hz. It's the floor, not a typical acoustic room bump. Not louder, just shakes. It does wonders...
31 Hz is oddly specific. Maybe it could be fixed with a high Q notch filter.

It can be fixed by moving the sub, or changing it from down firing to front firing. I kind of like it because it doesn't get louder, the floor just vibrates with it. In one scene an actress was pounding on a piece of glass. I thought the TV was going to crack. It's that cool.

There’s no right or wrong if you simply like it!:)
