What you need is a nice thick sheet of neoprene rubber instead. Then the
sound will come from your speakers and not from whichever bits of your

What's the "speaker"? The drive unit? That plus the box it's in?
That plus the room it's in?

The box, obviously.

Point proved, I think!

One person thinks spikes couple. Another thinks they decouple.
Someone else wants to consider the box containing the drivers (the
"speaker") separately from the room it's heard in.

Some would put a record deck on an absorbent mat. Some on wooden
cones then on a glass shelf then on more cones, or maybe spikes. But
I think they'd all leave the deck's suspended sub-chassis alone?

Audiophle logic.

In the context of the thread, in which the speaker was the thing being
put on spikes or a neoprene mat, clearly "speaker" referred to the box.

Clearly room acoustics and interaction between the room and the speaker
are important, but that doesn't justify conflating the terminology so
that "speaker" is defined as including the room.

Garrard 301, etc, had no suspension and some mounted them in concrete. ;-)
