Default Isolating speakers from the floor

Has anyone got any experience and suggestions of DIY methods of isolating
speakers from the floor? I'm looking to do it to reduce the amount of noise
transferred through the floor to downstairs, rather than as a method of
altering sound quality.

This is not easy; if you make an isolation system that works down to an
adequately low frequency, it is likely that the speakers will be
unstable and wobbly. You could always hang them from the ceiling. Anyone
living above?

** That is 100% IDIOT advice.

The cabinets are NOT responsible for shaking the floor.

Well, you answer the question then - do you need me to repeat it?

Agreed.

The mass of the enclosure is usually very large compared to the mass of the
speaker cone. Newton's Law about actions and reactions is relevant. Bottom
line, the cabinet does not transmit much sound through its feet.

Problems with transmission of sound, whether laterally or vertically, are
overwhelmingly based on response to the acoustical output of the speakers.

I've seen situations where speakers have been hung on fishing line just
strong enough to not break. and they sounded and transmitted sound into
adjacent rooms identically the same as they had been situated in the same
location and orientation by more conventional means.

** Totally impossible.

The low frequency sound pressure in the room is what shakes the floor.

** Just pour several tonnes of concrete over the whole upper floor of your
place.
