Loudspeaker isolation ...

[Purité Audio]

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.

FWIW,

The National Research Council of Canada measures isolation products:

Concrete slab floors and no seismic activity here..

You want a sandbox for isolation?

My whole house sits on one.

imagine it's violin/viola/cello/bass
strings are your loudspeaker
feet are sound post

why the same set of strings never sound the same?

just a quick analogy i could think of, please enlighten me if I'm wrong

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!

Perhaps we can refer to Dr. Toole and his fondness for full body bass.

I think "isolation products," inasmuch as they do anything, primarily benefit rooms other than the listening room. Particularly rooms above and below it.

Wait a minute - this is a glorified sales brochure. How about what the NRCC actually said?
