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.


If I have understood the question correctly...

....have you considered a good boarding school?

His parents won't pay for it. ;-)

I'm not sure what they'd think of me as a pupil at my age...

If the problem really is transmission of vibrations then decoupling the
speakers from the floor with a layer or two of carpet and a bit of mass
like a paving stoneon top would help. Assuming, of course that you can't
fix them to the wall.
Cutting the low frequencies might be a better approach.
At the end of this road of course lie headphones.....

Makes little difference - the sound waves produced by the speaker will
still go through the floor.

It'll make a fair bit of difference. Solids are rather better conductors of
acoustic energy than air is. So if the speakers are mechanically coupled to
the floor a lot more acoustic energy will be transferred to it that if the
only coupling is via the air inside the room.

** Shame how the damn cabinet is NOT the source of the sound pressure in
the room.

That pressure, distributed all over the floor area IS the cause of floor
vibrations.

So if the speakers are mechanically coupled to the floor

Only in our dreams.

True, but... There's a lot more air in play. Lots.

Not really.

I have a friend who hangs his speakers from the ceiling with the thinnest
possible fishing line. Very stable in its way, and also about as flexible as
one could hope for. Makes virtually no change in the amount of bass that is
transmitted.

Bah. I was of the impression that most speaker stands deliberately attempt
to couple the speaker to the floor to alter sound quality / quantity. My
first thought was to stick the speakers / stands on something heavy, and
stick the stack of speakers and heavy thing on a rubber mat, with the hope
that the weight of the heavy thing would absorb some of the energy.

P'raps I should get some of eggbox foam - some of the lads did survey work
in some anechoic chambers and apparently you could bearly hear each other
unless you were face to face.

That's a different argument.

something heavy, and stick the stack of speakers and heavy thing on a

A thick and heavy mat covering the whole floor would be more like it.
Although mainly for higher frequencies.

That was to treat the acoustics of the room and will have little effect
on sound transmission in/out of it, especially at LF. For that you need
mass - lots of it.
